The History Of Computer Development Essay

698 words - 3 pages

Every generation of computer experienced a major technological development that basically changed the way computers operate, thus resulting in increasingly smaller, cheaper, more powerful and more efficient and reliable devices .The history of computer development is always referred to in reference to the different generations of computing devices.

The first generation (1940-1956) is the Vacuum Tubes. The first generation computers used vacuum tubes for circuitry and magnetic drums for their memory, and because of that they big and were often large, taking up entire rooms to build. They are so expensive to operate because they are very large and took a lot of maintenance and in addition ...view middle of the document...

Although the transistor is still generating a huge deal of heat that results in the computer to damage, it was a great and intelligent improvement over the vacuum tube. The second-generation computers are still relied on the punched cards for input and the paper printouts for output. The second-generation computers have moved from cryptic binary machine language to languages, or assembly, symbolic, which will allow the programmers to specify the instructions in words. At this time, high-level of programming languages are also being developed, such as the early versions of COBOL and FORTRAN. These were also the first computers that able to store their programmer instructions in their memory, which moved from a magnetic drum to magnetic core technology. The first computers of this second-generation were developed for the atomic energy industry.
Third Generation (1964-1971), the Integrated Circuit. The development of the integrated circuit was the pioneer of the third generation of computers. The same transistor, but miniature in size and placed on silicon chip, that are called the semiconductors, which dramatically increase...
