The History of Computers

Whether you know it or not you depend on computers for almost every thing you do in modern day life. From the second you get up in the morning to the second you go to sleep computer are tied into what you do and use in some way. It is tied in to you life in the most obvious and obscure ways. Take for example you wake up in the morning usually to a digital alarm clock. You start you car it uses computers the second you turn the key (General Motors is the largest buyers of computer components in the world). You pick up the phone it uses computers. No mater how hard you try you can get away from them you can't.
It is inevitable. Many people think of computers as a new invention, and in reality it is very old.

When it was finished in 1950 it became the fastest computer in the world.17 It was built by the National Bureau of standards on the campus of UCLA. It was names the
National Bureau of Standards Western Automatic Computer or the SWAC. It could be said that the SWAC set the standards for computers for later up to present times.18 It was because the had all the same primary units. It had a storage device, a internal clock, an input output device, and arithmetic logic unit that consisting of a control and arithmetic unit. These computers were considered first generation computers (1942 - 1958). In 1948 John Bardeen, Walter Brattain, and William Schockley of Bell labs file for the firs patent on the transistor.19 This invention would foundation for second generation computers (1958 - 1964). Computers of the second generation were smaller(about the size of a piano now) and much more quicker because of the new inventions of its time. Computers used the much smaller transistor over the bulky vacuum tubes. Another invention which influenced second generation computers and every generation after it was the discovery of magnetic core memory. Now magnetic tapes and disks were used to store programs instead of being stored in the computer. This way the computer could be used for many operations without totally being reprogrammed or rewired to do another task. All you had to do was pop in another disk. The third generation(1964 - 1970) was when computers
