History of Computer-important peopleAllen, Paul G. - Co-founder of Microsoft Corp. Allen left the company in 1985 but remained on the age of directors and as founded or financially supported several innovative computer ventures, including Asymetrix and Starware Corp. He is involved with a variety of other projects, including a Jimi Hendrix Museum in Seattle.Amdahl, comp iodinnt M - South Dakota native who helped design the IBM 704, the S/360 series. He was the founder of the Amdahl Corp.Andreessen, Marc - Co-founder (at the age of 22) of Netscape Communications, along with Silicon Graphics founder James H. Clark. Before Andreessen gradatory from the University of Illinois in Champaign, he had created the NCSA Mosaic prototype with a team of students and staff at the universitys National Center for Supercomputing Applications.Babbage, Charles (1791-1871) - Eccentric, English mathematician who is considered to have conceptualized the modern computer a century before technology let it be built. He conceptualized the Difference Engine, a machine that would have computed lengthy scientific tables, but money, labor, and health problems prevented its completion. The analytic Engine, a much ambitious plan, would have done a wide range of calculating tasks. With it, Babbage recognized the need for an input device, memory, a central affect unit, and an output device, and for this he is known as the Father of Computing.Backus, John W. - Mathematician from Philadelphia who headed the research team at IBM that created FORTRAN, the first machine independent programming language.-important devices/developmentsFloppy mystify - The floppy drive is always called "Drive A". A floppy disk screwing hold 1.5 megabytes of data. Thats about 1,500,000 characters or letters (or about 300,000 words). Thats more than enough space for the text of a large book. Pictures, however, take up a great deal of room. You could only fit a small bod of good-quality pictures (or grap hics) on a floppy disk. Hard drive - This drive uses disks that are made of aluminium or glass (and therefore challenging). Each disk can store much more information than either a floppy or CD-ROM. Sometimes, there may be several disks in a hard drive. However, the disks in a normal hard drive can not be removed or replaced. Today, hard drives are measured in gigabytes. Thats one thousand million bytes. 1 gigabyte is about 11/3 CD-ROM disks.Motherboard - Everything inside the computer is connected to a circuit board called the motherboard.
