The computer had to be rugged and fast, with advanced circuit design and reliable packaging able to withstand the forces of a missile launch. The military’s high standards for its transistors pushed manufacturers to improve quality control. When the Minuteman I was decommissioned, some universities received these computers for use by students. Ferranti Mark I Sold Based on ideas from Alan Turing, Britain´s Pilot ACE computer is constructed at the National Physical Laboratory. The design packed 800 vacuum tubes into a relatively compact 12 square feet. This type of computer is useful in performing many of the mathematical equations scientists and engineers encounter in their work. It was originally created for a nuclear missile design project in 1949 by a team led by Fred Steele. Steve Wozniak Completes The Apple Typically, computer users of the time fed their programs into a computer using punched cards or paper tape. Ross contended that a Flexowriter -- an electrically-controll

Before its decommissioning in 1952, the SSEC produced the moon position tables used in early planning of the 1969 Apollo XII moon landing. These tables were later confirmed by using more modern computers for the actual flights. The SSEC was one of the last of the generation of 'super calculators' to be built using electromechanical technology. The machine had a fifty-foot long camshaft running the length of machine that synchronized the machine’s thousands of component parts and used 3,500 relays. The Mark 1 produced mathematical tables but was soon superseded by electronic stored-program computers. A computer is an electronic device that manipulates information, or data. You may already know that you can use a computer to type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos. It performed 2 million instructions per second, but other RISC-based computers worked significantly faster. The

At its introduction, it was listed as the second fastest supercomputer in the world and this single system increased NASA's supercomputing capacity 10-fold. The system was kept at NASA Ames Research Center until 2013, when it was removed to make way for two new supercomputers. Nearly a quarter century after IBM launched their PC in 1981, they had become merely another player in a crowded marketplace. Lenovo, China's largest manufacturer of PCs, purchased IBM's personal computer business in 2005, largely to gain access to IBM's ThinkPad line of computers and sales force. Lenovo became the largest manufacturer of PCs in the world with the acquisition, later also acquiring IBM's server line of computers. Classification Of Computers In mid-2012 the most powerful upercomputer was a Linux-based IBM Sequoia-BlueGene/Q system powered by Power BQC 16-core processors running at 1.6GHz. The system, installed at Lawrence Livermore National Laboratory and called Jaguar, has
