What Is the Computer History Timeline?

I Am Computer Engineer Student want to know about the brief history of Computer? I have visited several site to get the information but not satisfied with that experienced so if you guys have some information regarding that then please suggest me.

Although we lean to think of computers as only being of the most modern generations, they actually started in the past 1940. The first CNC also known as (Complex Number Calculator) was first developed by George Stibitz in Bell Telephone Laboratories at 1940, by using tele type mechanism it perform calculation. In 1941 in order to meet and process intelligence the British Bombe computer was set up, The center of a patent was build at that time and it last for 1942 to 1973 and name as The Atanasoff-Berry Computer (ABC), until 1973 this concept was declared un-patentable. At Harvard University the MARK computer was designed by Grace Hopper and Howard Aiken in 1944.The first BUG was discovered in 1945 for the computer which lead to the failure of this generation at that time. In 1947 the first cathode-ray tube was discovered by Sir Frederick Williams which was used as storing devices which later evolve into RAM. For the commercial use the first computer was sold for $750,000 plus the printer for about $185,000 to the U.S. Census Bureau. In 1953 the IBM came to the screen. The Microsoft Corporation founded by Paul Allen and Bill Gates in 1975. Sony and Philips introduced CD-ROM in 1985. Google started in 1998

The era of computers start out about long years before, in 1642 the main digital computer was billed by Blaise Pascal. After that in World War 2 their start the large need of computer John Mauchy and their contacts decided to create this electronic device. So they build up ENIAC which was 1000 time quicker then old one. ENIAC used about 1,800 four-sided figure feet of base space, and consumed lots of electrical power. After the huge success of ENIAC the John Von Neumann in 1945 decided to build computer which will be faster then that. So he developed special mechanism called as CCT (Conditional control transfer) by which he can stop and start the execution of system. In 1960 the need is arise for the better and faster computer at that time LARC machine was introduced which support Console, Card feeder, laser printer, and graphic devices. By 1980 by using microprocessors a number of computers run and handle 32 bits of data at a point, that mean they can process 4,000,000 instructions per second. In 1980 the FORTRAN language was introduced.

According to the generation of the computer, The first generation of computer which is also known as Vacuum Tubes was developed in 1940 to 1956. After 1956 the era of Transistor came which is the Second generation which swap the vacuum tubes, at that time the language such as FORTRAN and COBOL were mostly used this type of computer mostly use by Atomic Energy Industries. In 1971 the integrated circuit was developed which become the mark of the third generation of computers. At that time in 1971 the user interacts with the System by using input devices such as Keyboard and Mouse. Now at present that is forth generation is the world of microprocessor based system. This kind of processor contains thousand of integrated circuit to develop a single silicon chip. As compare to the first generation this is small in size which can be used on the palm of the hand. The first chip named as Intel 4004 was developed during 1971. Today networks are recognized by this small powerful computer, the major advantage of using this is that it provides GUI to the user, which was not likely for the first generation computer. And the fifth generation which is still under development by artificial intelligence, this kind of computer used the technique of parallel processing to make the system additional useful for the creature era.
