The History of Computer Development Essay - 608 Words

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 they use a great deal of electricity and similarly†¦show more content†¦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 magne tic 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 the speed and efficiency of the computers. Instead of punched cards and printouts, users interacting with third generation computers by using the keyboards and monitors and interfaced with an operating system, which allowed the device to run through many different applications at same time with a central program that monitoring the memory. Computers for the first time became an accessible to a mass audience because they were smaller, faster and cheaper than theirShow MoreRelatedHistory of the Development of Computers Essay1718 Words   |  7 PagesDEVELOPMENT OF COMPUTERS As we are stepping towards the era of 2020, man have consistently been innovative and creative in developing and improving technology for various sectors to make the world a better place for us to live in.

IBM was already a big name in the market of mini, middle range and mainframe computers. The perspective and promising small computer market, greatly gaining ground due to Apple II and other few, was still a difficult task despite their multi-millionaire efforts. IBM decided to develop the model 5150 on the lines of their first PC model 5100, which was pretty unaffordable for large masses.
