What Is The Bermuda Triangle History Essay

What Is The Bermuda Triangle History Essay The Bermuda Triangle is also known as the Devils Triangle. It is an area located on the north western Atlantic, in the country of International waters, The Bahamas. The Bermuda Triangle is an extremely dangerous area for one to enter. Aircrafts and surface vessels are believed to have vanished in weird ways which are considered human error, piracy, equipment failure, or natural disasters. Important things in society have shown some of these disappearances could have been the laws of physics, paranormal, or actions performed by aliens. I. The Triangle is located between the cities of Fort Lauderdale, Bermuda, and Puerto Rico. A. The Bermuda Triangle is nicknamed the Devils Triangle. B. In this triangle, it is said that a lot of things in weird ways happen. II. One of the most famous disappearances is the Naval Air Flight 19. A. 13 Avenger bombers handled by Lt. Charles Taylor left the Naval Air Station in Fort Lauderdale on routine mission to practice bombing. B. As they all were trying to go back home, Lt. Robert Cox overheard them trying to communicate over the radio. 1. Lt. Taylor informed Lt. Cox that they were in the Florida Keys, but didnt know how to get back to Fort Lauderdale. 2. Lt. Taylor was actually over the Bahamas not the keys and only kept going to go further out into the sea. III. Rescue teams were sent out to find Flight 19. A. A Martin Mariner did not make its schedule and did not answer calls. B. Flight 19 was never found, neither was the Mariner. Conclusion: For years there has been an unsolved mystery of disappearances of boats and planes with no trace of evidence left behind. Could it be human error? Equipment failure? There are a lot of different things that could have happened with every disappearance within this dangerous area, the Bermuda Triangle. Many believe these disappearances are laws of physics, paranormal, or actions performed by aliens. But, nobody knows. All in all, the Bermuda Triangle is left open for everyones own belief. Since there was no proof of piracy, hurricanes, UFOs or any wreckage found, this is a case of mysterious incidents that will forever be unknown. The Bermuda triangle The Bermuda Triangle is also known as the Devils Triangle. It is an area located on the north western Atlantic, in the country of International waters, The Bahamas. The Bermuda Triangle is an extremely dangerous area for one to enter. Aircrafts and surface vessels are believed to have vanished in weird ways which are considered human error, piracy, equipment failure, or natural disasters. Important things in society have shown some of these disappearances could have been the laws of physics, paranormal, or actions performed by aliens. The Bermuda Triangle is at a status of an Urban Legend. Many events that have been reported or witnessed by people, and many administration agencies have put on record as addressing that the amount and nature of vanishes is very much alike to any other part of the ocean, but people that support paranormal phenomena suggest that many events stay unexplained regardless of any huge investigation. The border of the Triangle depends on who found it; some say its shape is like a trapezoid covering the straits of Florida, the Bahamas, and the whole area of the Caribbean Island and the Atlantic east to the Azores; others add it to the Gulf of Mexico. The more well known triangular area in a lot of documents has its parts somewhere on the Atlantic coast of Florida, San Juan, Puerto Rico, and the mid-Atlantic Island of Bermuda, with a lot of the accidents not happening as much along the southern border around the Bahamas and Florida straits. The area is one of the biggest sailing lanes in the world, with ships crossing through it every day for traveling in the Americas, Europe, and the Caribbean Islands. Cruise ships are so big, and comfortable made to go back and forth between Florida and the Islands. It is also a huge flown route for commercial and private aircraft going towards Florida, the Caribbean, and South America from points north. When the Legend of the Triangle showed up in newspapers by E.V.W. Jones on September 16, 1950 through the Associated Press, it was the first article of any kind. Two years after that, Fate Magazine published Sea Mystery At Our Back Door, a small article by George X. Sand that covered a lot of things from the loss of a few planes and ships, the loss of Flight 19, and a group of five U.S. Navy TBM Avenger bombers on a training mission. The familiar triangular area was where the losses happened and Sands article was the first to tell all about it. American Legion Magazine would cover Flight 19 in the April 1962 issue. The issue stated that the flight leader was heard saying, We are entering white water, nothing seems right. We dont know where we are, the water is green, no white. Also, the officials at the Navy board said that the planes flew off to mars. This was the first article to have people curious about Flight 19, but it would take another author, Vincent Gaddis, to write about i t in the February 1964 Argosy Magazine to take Flight 19 and put it together with other disappearances and put it under a new different name, The Deadly Bermuda Triangle, he would write more on that article with a better detailed book, Invisible Horizons, the next year. Others would go on with their own books, like, John Wallace Spencer (Limbo of the Lost, 1969-1973), Charles Berlitz (The Bermuda Triangle, 1974), Richard Winer (The Devils Triangle, 1974), and a lot of others, which they were all staying on the same topics made by Eckert. A research librarian, Lawrence David Kusche, from Arizona State University and author of The Bermuda Triangle Mystery: Solved (1975) has learned a lot more about how he has been writing. His research gave out a lot of errors and disagreements between statements from eyewitnesses and Berlitzs stories, victims, and other people involved in incidents. He stated cases where very important information did not get reported, like the disappearance of round-the-world yachtsman Donald Crowhurst, which Berlitz had showed it as a mystery, besides the good evidence he had. Another example was the story that Berlitz told as lost without a trace three days out of an Atlantic port when it had been lost three days out of port with the same name in the Pacific Ocean. There has also been a lot of incidents far outside of the area, which makes this area a lot more mysterious. The research that he would do was simple and easy. He would read newspapers and reports talking about the weather that was not m entioned in the stories. Kusche came up with some endings of what he had been researching. One, was that with all the ships and aircrafts that had gone missing was not much higher than in any other part of the ocean. Second, tropical storms that had happened in that area were not unlikely or mysterious, which Berlitz and other writers would usually not be able to talk about those storms. Last, was that some disappearances really did not happen. One plane crash was said to be seen by hundreds of witnesses off Daytona Beach, Florida. But, checking the local newspaper, nothing was said about it. Kusche believes that the Legend of the Bermuda Triangle is surely, a mystery. Other people have their own opinions and have done research as much as Kusche has. While the UK Channel 4 television program The Bermuda Triangle was being made by John Simmons of Geofilms for the Equinox Programme, the marine insurer Lloyds of London was asked if a lot of ships had sunk in the Bermuda Triangle area. Lloyds of London replied that the information he had received was not true and no ships had sunk there. The United Coast Guard have found their ending. The disappearances that have happened are close to as many ships and aircrafts that pass through and make it through the Triangle. The Coast Guard is still unsure about the Triangle, even though they get information and publish it, a lot of documents are filed with a lot of the events written by Triangle authors. One event involving the 1972 explosion and sinking of the tanker V.A. Fogg in the Gulf of Mexico, the Coast Guard took pictures of the wreck and found a few bodies. One of the Triangle authors stated that all the bodies had vanished, with the captains permission, who was found sitting in his cabin at his desk, holding a coffee cup. Curious researchers, like Ernest Taves and Barry Singer, have stated how mysteries and the paranormal are very popular and make good money. It started getting a lot of material on topics like the Bermuda Triangle. They were able to show that some of the pro-paranormal material is usually wrong or will not work, but its makers keep marketing it. They have claimed that the market is loaded with books, TV specials, etc. that help the Triangle mystery, and good researched material if people are curious about it. Finally, if the Triangle is thought of to cross land, like parts of Puerto Rico, the Bahamas, or Bermuda itself, there is no evidence for the disappearance of any land-based vehicles or people. The city of Freeport, found inside the Triangle, works a big shipyard and an airport which usually handles 50,000 flights, and is visited by over a million tourists a year. There are mysterious explanations of the incidents that have happened. Triangle writers have used a lot of weird ways to explain the incidents. One explanation blames it on leftover technology from the mythical lost continent of Atlantis. Sometimes put together with the Atlantis story is the deep rock composition known as the Bimini Road off the island of Bimini in the Bahamas, which is in the Triangle in some areas. Followers of the physic Edgar Cayce believe his prediction that evidence of Atlantis would had been found in 1968 which leads to the discovery of the Bimini Road. Believers describe the composition as a road, wall, or some other structure, even though geologists think it was already part of the land. Other writers think of the incidents as UFOs. The idea came from Steven Spielberg for his science fiction film Close Encounters of the Third Kind, which shows the lost Flight 19 as alien abductions. Then there is Charles Berlitz, the grandson of an amazing specialist in language and author of a lot of information on abnormal experience, has stayed with the same huge description, and thought of the losses in the Triangle to be abnormal or unexplained forces. There are also normal explanations of the events that have happened. Boundary problems are one of the big issues in a lot of Triangle incidents. Even though some people have guessed that unusual local magnetic abnormals can be in that area, like abnormals that have not been shown to even exist. Also boundaries have natural magnetic differences that are like Magnetic poles. For instance, in the United States the only places where magnetic north and geographic north are exactly the same on a line going from Wisconsin to the Gulf of Mexico. Navigators have known this for centuries. But the public is not as informed about it, and think there is something mysterious about a magnetic changing across an area as big as the Triangle, which it will eventually on its own. There are actions of destruction that happen on purpose. Actions of destruction that happen on purpose can be put into two types: acts of war, and acts of piracy. Records in enemy files have been checked for a lot of losses. While a lot of sinkings have been put to surface raiders or submarines during the World Wars and documented in a lot of the command log books, a lot of others that have happened in that type have not been proven. It might not be true that the loss of USS Cyclops in 1918, as well as her sister ships Proteus and Nereus in World War II, were put to submarines, but that information has not been found in the German records. Piracy is the act of taking a ship or small boat on the high seas, which is still happening today. In the western Pacific and Indian oceans, piracy for cargo theft is a lot more common, drug smugglers steal nice boats for smuggling actions, and could have been apart of crew and yacht disappearances in the Caribbean. Piracy in the Caribbean was common from about 1560 to the 1760s, and famous pirates like, Edward Teach (Blackbeard) and Jean Lafitte. Lafitte is sometimes said to be a Triangle victim himself. The Gulf Stream is almost connected to Bermuda itself. The Gulf Stream is an ocean current that is in the Gulf of Mexico, and then through the Straits of Florida, into the North Atlantic. It is a river within an ocean, and like a river, it can and does carry floating objects. It has a surface speed of up to about 5.6 mph. A small plane making water landing or a boat having an engine problem will be carried away from where its at by the current, just like it happened to the cabin cruiser Witchcraft on December 22, 1972, when it reported engine problems by the Miami buoy marker one mile from shore, but was not there when a Coast Guard got there. One of the biggest problems of explanations to the loss of any aircraft or vessel is human error. Whether on purpose or accidental, humans have been known to make mistakes making catastrophe, and losses in the Bermuda Triangle are not acceptable. For instance, the Coast Guard did not see very good training for the cleaning of volatile benzene residue as a reason for the loss of the tanker V.A. Fogg in 1972. Human stubbornness can have caused businessman Harvey Conover to lose his sailing yacht, the Revonoc, as he sailed into the beginning of the storm south of Florida on January 1, 1958. A lot of losses stay uninformed because there is not that much wreckage which could be studied, it has been talked about on a lot of important reports. Many people believe that hurricanes are the reason to every incident that deals with the Triangle. Hurricanes are powerful storms that are made in tropical waters, and have been responsible for thousands of lives lost and billions of dollars in damage. The sinking of Francisco de Bobadillas Spanish fleet in 1502 was the first recorded incident of a destructive hurricane. These storms have in the caused a lot of incidents like the Triangle. An explanation for some of the disappearances has studied on some of the big fields of methane hydrates on the continental borders. Laboratory experiments that have happened in Australia have proven that bubbles can, honestly, sink a scale model ship by lowering the density of the water; any wreckage consistently coming up to the surface would be highly taken away by the Gulf Stream. It has been proven wrong that periodic methane eruptions (sometimes called mud volcanoes) can make spaces of frothy water that can not give adequate buoyancy for ships. If that was true, an area like that making around a ship could cause it to sink very fast and without giving a warning. A white paper was published in 1981 by the United States Geological Survey about the appearance of hydrates in the Blake Ridge area, off the south eastern United States coast. Although, according to a USGS web page, no big releases of gas hydrates are believed to have happened in the Bermuda Triangle for the past 15,000 years. In many oceans around the world, rogue waves have caused ships to sink and oil platforms to go down. Those waves are believed to be a mystery and until just recently were believed to be a myth. Although, rogue waves do not account for the missing aircraft. A lot of incidents have happened throughout years in the Bermuda Triangle. Flight 19 was a training flight of TBM Avenger bombers that went missing on December 5, 1945 while over the Atlantic. The squadrons flight path was planned to take them east for 120 miles, north for 73 miles, and then back over a final 120-mile length that would take them back to the naval base, but they never came back. People believed that the flight happened in an unusual phenomena and usual magnetic readings, and that the flight happened on a nice day while being watched by an experienced pilot, Lt. Charles Carroll Taylor. What made the disappearance worse, was that the Navys report of the accident was said causes or reasons unknown. It is believed that Taylors mother wanted to save her sons reputation, so she made them write reasons unknown when actually Taylor was 50 km NW from where he thought he was. Adding to the whole mystery, a search and rescue Mariner aircraft with a 13-man crew was ordered to help the missing squadron, but the Mariner itself was never heard from again. Later, there was a report from a tanker taking off the coast of Florida of a seen explosion at about the time the Mariner would have been on duty. The basic facts of this description of the story are most likely usable, some important information is missing. The weather was getting stormy by the end of the incident, and naval reports and written recordings of the conversations between Taylor and the other pilots of Flight 19 do not say there were magnetic problems. With that, only Taylor had any good flying time, but he was not familiar with the south Florida area and had a history of getting lost in flight, that was done three times during World War II, he led planes into the water twice. Another incident was the Mary Celeste. The mysterious disappearance in 1872 of the 282-ton brigantine Mary Celeste but is not connected to the Triangle that much, the ship had been abandoned off the coast of Portugal. The incident got people confused with the loss of a ship with a similar name, the Mari Celeste, a 207-ton paddle steamer which hit a reef and sank fast off the coast of Bermuda on September 13,1864. Kusche stated that a lot of the facts about this incident were actually about the Marie Celeste, the fictional ship from Arthur Conan Doyles short story J. Habakuk Jephsons Statement (based on the real Mary Celeste incident, but fictionalized). There is also, the Ellen Austin supposedly came across an abandoned ship, placed on board a prize crew, and tried to sail with it to New York in 1881. According to the stories, it disappeared; others state that it reappeared without the prize crew, then disappeared again with another prize crew on board. A check of Lloyds of London records proved that the Meta existed and was built in 1854; in 1880 the Meta was renamed Ellen Austin. There are no real facts for this vessel, or any vessel at that time, that would have a lot of missing men put on board that later disappeared. Then there is the USS Cyclops. The event ending in one of the biggest loss of life in the history of the US Navy not connecting to combat happened when USS Cyclops, under the order of Lt Cdr G. W. Worley, went missing without a trace with a crew of 309 sometime after March 4, 1918, after leaving the island of Barbados. However, there is no strong evidence for a theory, a lot of independent theories exist, some blaming storms, and some suggesting that wartime enemy action was to blame for the loss. There is another, which is Theodosia Burr Alston. She was the daughter of the United States Vice President Aaron Burr. Her disappearance has been thought of a least once to be connected to the Triangle. She was a passenger on board of the Patriot, which sailed from Charleston, South Carolina to New York City on December 30, 1812, and was never heard from again. Piracy and the War of 1812 have been stated to be explanations, just like a theory putting her in Texas, far outside of the Triangle. Spray, is another incident that has happened. S.V. Spray was a fishing boat made as an ocean cruiser by Joshua Slocum and used by him to finish the first ever single-handed circumnavigation of the world, between 1895 and 1898. In 1909, Slocum set sail from Vineyard Haven heading for Venezuela. Not him or Spray were ever seen again. There is no evidence they were in the Bermuda Triangle when they disappeared, but neither is there any evidence of paranormal action. A five-masted schooner was built in 1919, the Carroll A. Deering was found abandoned at Diamond Shoals, by Cape Hatteras, North Carolina on January 31, 1921. Rumors at the time stated that the Deering was a victim of piracy, maybe connected with the illegal rum-running trade during Prohibition, and maybe involving another ship, S.S. Hewitt, which disappeared at about the same time. Hours later, an unknown steamer sailed by the lightship along the track of the Deering, and ignored all the signals from the lightship. It is thought of that the Hewitt could have been the mystery ship, and maybe involved in the Deering crews disappearance. On December 28, 1948, a Douglas DC-3 aircraft, number NC16002, disappeared while on a flight from San Juan, Puerto Rico, to Miami. No trace of the aircraft or the 32 people on board was ever found. From the documentation put away by the Civil Aeronautics Board investigation, maybe a hint to the planes disappearance was found, but hardly known by the Triangle writers: the planes batteries were looked at and found to be low on charge, but commanded back into the plane without a recharge by the pilot while in San Juan. Whether or not this led to complete electrical failure will never be known. Although, since piston-engine aircrafts depend on magnetos to help spark to their cylinders rather than a battery powered ignition coil system, that theory is not very believable. G-AHNP Star Tiger disappeared on January 30,1948 on a flight from the Azores to Bermuda; G-AGRE Star Ariel disappeared on January 17, 1949, on a flight from Bermuda to Kingston, Jamaica. Both were Avro Tudor IV passenger aircraft worked by British South American Airways. Works Cited Gian J. Quasar (2003).

(June 1974) http://www.unmuseum.org/triangle.htm (1995) Reflection I chose this particular topic on the Bermuda Triangle because I have heard many things about this triangular area. I figured if I did a project on it, I could find out myself and real facts instead of what people think. My family and I have always been interested in learning what the Triangle was and now I will be sure to inform them on what I have learned. I chose to make a map of where the Bermuda Triangle was located because I think people should known instead of trying to figure it out in their head. The visual has helped me also, so I am not trying to picture what it looks like. The three most important things I learned while doing this project was what occurred during the disappearance of Flight 19, Lawrence David Kusches opinion on the incidents, and last, how ships and aircrafts might sink within the Triangle. I never knew anything like what happened to Flight 19 could happen like that and how they could disappear and never be seen again, it amazes me. Kusches opinion on the incidents is that, it is all just a mystery that will never be solved. Finally, I would have never thought ships and aircrafts would able to sink even when flying, but I believe everything is possible. My Mom helped me out with this project, but knowing my Mom, she helps me out with everything and I love her for that. Most of the time, I worked on it myself and my Mom just helped me out with the final draft and the rough draft. I feel no body really influenced me throughout this project, maybe Kusche because he trully did hard work and I respect people who work hard. I do not think anyone will be affected by this project but I am sure they will love to here all the information I have gathered up. I can share this new information all around the community! Especially in my school, I know some people who want to know what the Triangle is all about and what really happens within it. Now, I have the answer. It is a mystery. I will use this information throughout the rest of my high school years and even maybe throughout college. The topic will probably get brought up and I will know a lot more then any body else. There is not three ways my perspective on life has changed from the information I learned but there is one way. To cherish every moment your living and to appreciate every body you have because you never know what the future holds and when people can just disappear. I believe that I could have done a few things different but not a lot. I could have organized my things better to where I would not have lost a lot of my notes but I dealt with it and continued my project. I think I could have managed my time better and maybe gotten the project done a little more faster. But, with all my hard work, I feel like I accomplished something! .

Roles Of The Operating System Computer Science Essay

Roles Of The Operating System Computer Science Essay All computers need some form of operating system so that communication between users applications and hardware. The OS also looks after the file system. With advancement in technology OS can now support more than one User, Task or Central Processing Unit (CPU). The OS controls the communication between applications and hardware. For the OS to communicate with these it installs device drivers for any hardware component that is inside the computer. the device driver is created by the hardware manufacturer and this is installed with the hardware software when installing. Thus allowing the OS to talk to the hardware its self. for example a wireless USB adapter (Fig1.1) would install a device driver as shown in (Fig1.2) Files and folders can be stored on the hard drive with the help of the OS creating a file structure on the hard disk its self enabling the data to be stored. Files are stored in a block of data that is treated as a single unit and is given a single name. Any files related to the same program are put in to folders so that the program is able to find all the data needed to run the program without needing to look all over the hard drive. Folders can also be stored inside other folders if they relate to a different part of the program or even an update folder or a uninstall program in the event you want to uninstall the program. These are call subfolders. (Fig 2.1) The structure in which files are stored on a hard drive are stored in a table called file allocation table. the table contains all the details of where each piece of data (such as blocks or clusters) is held that makes up the file on the hard drive. Depending on how the hard drive was formatted depends on the table format and cluster size. There are two different file structures which are: File Allocation Table 32-bit (FAT32) This can support partition sizes up to 2048GB (2TB) FAT32 can be used in Windows 95, Windows 98, Windows Me, Windows 2000 and Windows XP(Fig 2.2). New Technology File System (NTFS)This can support partitions sizes up to 16 Exabytes. 1 Exabyte is 260 bytes. With NTFS there is improved security features and extended attributes that the previous version used FAT32 (Fig 2.3). FIG 2.1Folders and Subfolders FIG 2.2 FAT32 FIG 2.3 NTFS User Interface Operating systems provide the user to interact with the software and the hardware by using two types of user interface called Command-line Interface (CLI) with this the user types commands in to the command prompt as shown in Fig 3.0 Graphical user interface with this the user interacts with menus, icons and applications as shown in Fig 3.1 Fig 3.0 Fig3.1 Applications Management Within the operating system one of the things it does is locates an application and loads it in to the RAM. Applications a software programs such as Microsoft Office word, Microsoft Office Excel, Microsoft Office PowerPoint, Games and many more. the OS will make sure that each application has enough system resources to run the program successfully. There is also a set of guidelines used by programmers to make sure that the application they are designing will work on an OS this is called Application Programming Interface (API) two examples of these are: Open Graphics Library (OpenGL) this is a cross-platform standard for multimedia graphics DirectX this is a collection of APIs for multimedia tasks for Microsoft Windows 1b. Within WindowsXP and Windows Vista Operating systems have the following features installed: Multitasking Multiuser Multiprocessing Multithreading Multiuser A multi-user operating system allows for multiple users to use the same computer at different times. So this mean that each user can have its own logon to windows where they can have their files can be secure so that only the user can see them. they can also set the computer display up however they want to such as picture backgrounds of the own choice and task bar settings changing the colour to their own choice. With the account been password protected and the files been stored on the same user logon this makes it secure. When logged on to the computer you can also switch users quickly what this does is keeps the first user logged on but just locks the account and takes you back to the user logon screen and enables you to log on as another user then once you have finished on that account you can just log of and then back at the logon screen you just click the first name again and type the password and you are right back in to it where you had left it so any programs that you had ope n are still open and you can carry on instead of waiting for the computer user settings to be applied making it much faster to change between users. Multitasking An operating system that is capable of allowing multiple software processes to run at the same time. So what this mean is that you can run many different programs at the same time. so you can be working on a document on Microsoft Office Word so the program will be loaded in to the RAM so that it can access it quicker when using the program. So your using the program then you need to use Microsoft Office Excel when you click open on the program it will also load it in to the RAM as well so that you can access the program data as well as the other program. This is multitasking. This would happen every time you opened a new program. Multiprocessing An operating system able of supporting and using more than one computer processor. Most modern computers support some form of multiprocessing. Multiprocessing doesnt require more than one physical CPU; it is simply the operating systems ability to run more than one  process  on the system. The operating system processes data one part at a time. Each process can execute a completely different program while most processes are completely independent. so if say you are running paint in windows and then open Microsoft office word even though it looks like it is doing them at the same time what it is doing is processing parts of the program one at a time. but because of the seep in what it processes them it gives the appearance that they are doing it at the same time. Multithreading Multithreading has many purposes one of these is to switch between different threads. However the main purpose is to increase the operation of a single core by monitoring and controlling the levels of threads. The tasks carried out by the user happen so frequently that the user does not actually see the threads and/or the tasks are running at the same time, with no fault. Another purpose of multithreading is used by the Operating System to break down a program in use into smaller, more manageable threads when it is required to carry out this specific task. Although it does allow individual programs to be multitasked. This is done because the hardware used for multithreading regularly operates alongside the software for multitasking. It is known for some CPUs to have more than one multithreading core; these are often referred to as processors. On multiprocessor, or multi- core systems, the tasks and threads generally run at the same time, with the support of each processor and/or core running a particular task on the Operating System. 1c. In both Windows XP and Vista there are functions installed on an OS. These functions might be at different levels depending on the OS. These functions are:- Backup Facilities File Management Security Backup Facilities Many backup facilities are used here are a few examples: Daily Copy Normal Incremental Differential Daily A daily backup only saves files that have been modified on that day. This type of support does not modify the other files. Copy This type of support only copies the data and files chosen. For instance a word document is saved in one folder and you copy to another folder of the same OS. This backup can be found in all Windows software. Normal This type of support (full backup) is when the selected files and folders are to be stored and are archived to the hard disk drive. For example an Excel spreadsheet that is being saved for the very first time. Incremental This type of backup saves all folders and files that have been created or modified since the last normal backup. A benefit of this is that the backup times are faster as only the file needs to be saved. However, a drawback of this is that the recovery time of the file will be a lot longer as the data has to be restored from the last incremental backup and/or another backup device. Differential This backup saves all files a nd folders that are created or changed since either the last normal backup. These files are not archived, on the other hand they are copied at the starting point until the next incremental or full backup is complete. Making this type of backup is important as to restore the data you would only need the last full and differential backup. File Management File management is also very similar in Vista and Windows XP. Generally it is a lot easier to manage files and directories in Windows XP than it is in Vista because in Windows XP the graphical user interface I find is much more user friendly. There are options to make Vista act and look like Windows XP through; Start, Control Panel, Appearance and Personalization. Both XP and Vista use NTFS file management. However, in Windows Explorer the file management enforces/performs a hierarchical structure. Below is a broken down step by step of what happens when creating a file in a directory: The OS controls and creates the file structure and directories The hard drive allows data to be stored in this structure The file is then stored on to the hard drive and is given a name or commonly known as a single unit/name The directory programs and data files group all the files together and create the directory (Some directories can be stored in other directories these are commonly known as subdirectories) One last point about directories and subdirectories is that their commonly used name is now folders and subfolders, respectively. Security There are four main ways in which to protect computer systems, these are: Firewall This provides protection against any online threats. Anti-virus software which tries to protect the operating system from any malicious threats that could occur. Passwords is used to protect the contents of the operating system and is a method of controlling who access to it. Encryption is used to prevent people accessing documents they are not permitted to see. The main security feature for Windows XP is designed to continuously monitor the status of the computers security system settings and should a problem occur the operating system will provide a pop up to warn the user of the problem. This security system is referred to as the security centre. Windows Vista has a similar security feature called Windows Defender, however Windows Defender has a few additional features.

The World Wide Web Essays -- Internet Technology Computers Essays

The World Wide Web Communication--it is a fundamental part of our everyday lives. It characterizes who we are, what we do, and how we relate to others in society. It is a very powerful tool that holds many different uses for our basic needs and survival. At a very simplistic level, it is key in attaining our very basic needs for survival. In that respect, it is key in achieving all needs in Maslows hierarchy. Its uses and possibilities endless. Over time, the discoveries that have been made in relation to communication have been revolutionary in that they have changed the way we live and act dramatically.

But, what they all have in common is that they have impacted our lives and the way in which members of society relate to one another, understand and percieve one another. As technology advances, the ways in which we communicate will change and advance. In 1992, the inception of the World Wide Web brought about, which at that time many people were unaware, a revolution in the communication industry.

Franco Zeffirelli And Baz Luhrmanns Romeo And Juliet :: William Shakespeare

Franco Zeffirelli and Baz Luhrmann's Romeo and Juliet Sex, drugs, and violence are usually a potent combination, and only William Shakespeare could develop them into a masterful, poetic, and elegant story. In the play, "The Tragedy of Romeo and Juliet," all these aspects of teenage life absorb the reader or watcher. It is understood that Hollywood would try to imitate this masterpiece on screen, and it has done so in two films: Franco Zeffirelli's 1968 "Romeo and Juliet" and Baz Luhrmann's 1996 "William Shakespeare's Romeo and Juliet." The updated Luhrmann picture best captures the essence of Shakespeare for the present-day viewer. Through the ingenious use of modernization and location, while preserving Shakespearean language, the spirit of Shakespeare emerges to captivate a large audience. Shakespeare's plays were designed to adapt to any audience: with this in mind, Baz Luhrmann created a film that applies to the modern audience through this updating. Luhrmann modernizes "Romeo and Juliet," through constant alterations of the props, which entice the audience into genuinely feeling the spirit of Shakespeare. First, the movie starts with an prologue masked as a news broadcast on television. This sets the scene of the play by illustrating the violence occurring between the two wealthy families, the Montagues and the Capulets. In Zeffirelli's film of "Romeo and Juliet," the prologue takes the form of a dry narrator relating the story of the Montagues and Capulets over a backdrop of an Italian city. For most modern viewers (especially teenagers), the Luhrmann picture is fast-paced, keeping the spectator intrigued, while the Zeffirelli picture is dreary and dull, an endless maze of long and boring conversations, foreshadowed by the prologue. In Luhrmann's film, the actors, instead of carrying swords with them, hide guns in their shirts and wield them expertly. The death of Romeo and Juliet is (as always) blamed on the post office, for not delivering the letter properly. And, to be politically correct, Mercutio appears at the Capulets' ball dressed as a large woman. The actors in Zeffirelli's version of Shakespeare wear colored tights and bulging blouses; thus they appear more comical because they are outdated. By modernizing these aspects of the play, and reconstructing the prologue, Luhrmann creates a movie that is more interesting to the modern viewer, and captures the essence of Shakespeare's writings. Evidencing this viewer-friendliness, the 1996 "William Shakespeare's Romeo and Juliet" made almost twelve million dollars in the month of November alone due to its clever alterations. As well as updating Shakespeare's play to the present decade through props, Baz Luhrmann's film is more enjoyable because of the vibrant settings. The Zeffirelli's "Romeo and Juliet" occurs in an ancient Italian city, with

Differences between men and women Essay

What is the difference between males and females? We notice the different dressing styles, different roles in the workplace and how we spend our leisure time, how we wear our emotions, and also how differently we think. But a question arises. Are males and females really different in every aspect? The first question we ask when a baby is born is: â€Å"Is it a boy or a girl?† Though most people accept most of the socially prescribed roles for the gender they were born with, some struggle against what they see as rigid and arbitrary social norms. In this essay, I will describe and give my input on the roles of human sexuality and gender. Most people think of sex and gender as one and the same when in fact they are not. Wood, Wood, and Boyd (2005) define sex as â€Å"a biological term, while gender is more commonly used to refer to the psychological and social variables associated with one’s sex† (p. 410). In the biological approach, when defining the sociocultural characteristics of masculinity and femininity, cultures look into the behaviors each gender should act upon. Males should be the dominant figure. They should be strong, competitive, be able to stand their ground, confident, and independent. Women on the other had are expected to be the exact opposite. They should be dependent, caring, encouraging, emotional, and nurturing. As children approach the age of two or so, they start to realize the roles such as attitudes, interest, and behaviors, in which males and females are supposed to portray. This is referred to as gender typing. When understanding which roles are to be taken, then they can star t their development. In the psychoanalytic theory, Freud asserts that children’s thoughts about gender occur out of a clash relating to their feelings about their parents. Generally, they would like to tie a bond between the opposite-sex parent but end up doing so with the same-sex parent in order to settle this clash, taking on that’s parent’s gender-related behavior and ideas. â€Å"At the same time, they defer their love for the opposite-sex parent in the hope that someday they will be able to achieve a sexual relationship with a partner who is similar to him or her† (Wood et. al., 2005, p. 411). I can agree with Freud’s psychoanalytic theory to a certain extent. What  would the opposite-sex parent do in a family with no boys or no girls? Would he/she take over some traits that the same-sex parent would give to the children? My mother and father had four boys including myself. Being in the situation my mother was in considering there were no girls, she felt a need to rub off some of her traits to us boys. While my father taught us the game of baseball and how to mow the lawn, my mother taught us our table manners and to how to do the laundry. We shared a bond to both of our parents equally. But overall, we all feel the same way in which we want our future wives to be close to, if not exactly like our mother. In the social learning theory, children look for role models to follow, where they imitate that person and want to be like him/her. But say if a boy started doing something that is out of his gender role, such as trying on his mother’s high heels, he will be informed by his father that it is not appropriate for him to do such a thing. Psychologists say that yes imitating and reinforcing may play a part in the gender role development, but it does not offer a complete clarification of this occurrence. Lawrence Kohlberg’s cognitive developmental theory â€Å"suggests that an understanding if gender is a prerequisite to gender role development† (1966; Kohlberg & Ullian, 1974, p. 412). This theory explains that children go through three stages that are necessary to developing the concept of gender. The first stage happens when the child is around the ages of two and three, which is gender identity, or the sense of being male or female. The next stage occurs at four and five, which is gender stability, the understanding that boys will be boys and girls will be girls forever. Then the last stage is when the child has reached six and eight. It is known as gender constancy, or the knowledge that gender will not change, despite the clothes they wear or the activities they participate in. But Kohlberg failed to mention â€Å"why many gender-role appropriate behaviors and preferences are observed in children as young as age 2 or 3, long before gender constancy is acquired† (Bussey & Bandura, 1999; Jacklin, 1989; Martin & Little, 1990, p. 412). I guess it just depends on the educational techniques used on the children. My brothers and I were taught a lot at a very young age, so we had a little bit of a head start. Like the cognitive developmental theory, Sandra Bem’s gender schema theory (1981) emphasizes that children begin to use gender as a way to pick up and sort out information. But the gender schema theory says that this process happens earlier with the gaining of gender identity other than gender constancy. Also like social learning theory, the gender schema theory indicates â€Å"young children are motivated to pay more attention to and behave in ways consistent with the gender-based standards and stereotypes of their culture† (Wood et. al., 2005, p. 412). I think television can become a major factor in a child’s behavior because they can watch shows that are unsuitable for their viewing, and while growing older they can become more fascinated with sexual activity. When becoming sexually involved with another person, both males and females experience four phases of when engaged in sex, called the sexual response cycle. The first phase is the excitement phase, and this is simply when the female undresses for the male and the male uses verbal expressions of affection to stimulate the female. The blood flow starts pumping and the heart beats faster and faster until they reach the second phase, which is the plateau phase. Here excitement keeps rising for the preparation of the third phase, the orgasm. While males only have one, females can have multiple. After that, everything starts to slow down and goes back to its unaroused state. This is known as the resolution phase or the tapering-off period. Sexual activity varies from culture to culture. Furthermore, â€Å"what is perceived as sexually attractive in males and females may differ dramatically† (Woods et. al., 2005, p. 421). Agreed, differences in attraction may occur, even with the same sex. Someone’s sexual orientation describes the preferences at which someone is attracted to either the opposite or that of their own sex. Studies show that males are twice as likely to be homosexual than females. Berenbaum & Snyder (1995) say that if the androgens, or hormones that make one masculine, are too high or too low, can make the brain develop more masculine or feminine which homosexual orientation is more likely. Most of the time it is all in the genes, but other times it is that person’s choice to be homosexual, even  if others may not be on the same page. Some people can be homophobic, which in my view is extremely improper. Whoever thinks that it is wrong should take a step back, let those people live their lives and start worrying about their own. I have known many people who were homophobic and it just pushed my buttons to see how cruel they can be to someone with a different sexual orientation. I do see where they are coming from, on the other hand. I do think it is weird to see two homosexual men holding hands or kissing, but I always come to an understanding that they are who they are and nothing can change that. They want to feel the comfort of another. In general, they want to love just as much as heterosexual couples do, so I praise them for that. With homosexual activity and even heterosexual activity, there comes a price if a couple chooses to have unprotected sex. There are many sexually transmitted diseases (STDs), but the major ones are Chlamydia, gonorrhea, and syphilis, which all can be cured by antibiotics. Chlamydia and gonorrhea are critical to women because if they in fact do have any of these, they do not have any early stages of infections. Since they do not treat it on time, then it can lead to infertility. Viral STDs include genital herpes, genital warts, and acquired immune deficiency syndrome (AIDS), which cannot be cured. The human immunodeficiency virus (HIV) is the virus that causes AIDS. It attacks the immune system, and can cause cancer or other dysfunctions. In order to prevent spreading STDs one should avoid sex with multiple partners, and also use a latex condom with a spermicide. With the growing rate of STDs nowadays, and the amount of television commercials informing teenagers and adults to practice safe sex and get tested for HIV or AIDS, I do not understand why people still have unsafe sex. It is not that difficult to â€Å"strap up† before â€Å"doing the deed† or â€Å"keep it in your pants,† that is unless you are prepared to have a child and have been tested along with your partner. I have known many males and females who have had unprotected sex and regret ever doing so, a couple of which becoming pregnant. From their point of  view, they feel lost because they cannot support their children and give them the attention they need in order to have a secure, fulfilling childhood.
