and generation of computer. 2. Definition of Mechanical Calculating Device. * First Generation (1941-1956) World War gave rise to numerous developments and started off the computer age. Electronic Numerical Integrator and Computer (ENIAC) was produced by a partnershp between University of Pennsylvania and the US government. It consisted of 18‚000 vacuum tubes and 7000 resistors. It was developed by John Presper Eckert and John W. Mauchly and was a general purpose computer. "Von Neumann designed

Computers have become such indispensable devices in the modern era that we cannot imagine life without computers. However‚ there have been different ideas on the benefits of computers. In my opinion‚ computers do more good than harm because they can make life easier and also can help our work become more systematically and productively. Firstly‚ computers give many advantages as they can make life easier. As a student‚ many works must be done by using computer such as assignment and presentation

-- -- - The Evolution of XTP† Greg Chesson Silicon Graphics Computer Systems Mountain View‚ Ca 94039-7311 greg@sgi.com Abstract The design of XTP has been a 3 year process so far with roots traceable to work in the 1970’s and 80’s. There have been roughly ten distinct revisions of the protocol. Since Revision 3.4 in June 1989 there has been an effort to stabilize the design. This has been accomplished. The most recent versions - Revision 3.4 and 3.5 - were about 14 months apart whereas

A computer is a machine that is able to take information (input)‚ do some work on or make changes to the information‚ to make new information (output). Computers have existed for much of human history. Examples of early computers are the astrolabe and the abacus. Modern computers are very different from early computers. They are now very powerful machines that are able to do billions of calculations every second. Most people have used a personal computer in their home or at work. Computers are
