History of Computer-important peopleAllen, Paul G. - Co-founder of Microsoft Corp. Allen left the connection in 1985 but remained on the board 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, Gene M - randomness 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, on with Silicon Graphics founder James H. Clark. Before Andreessen graduated 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 i t be built. He conceptualized the deflexion Engine, a machine that would have computed lengthy scientific tables, but money, labor, and health problems prevented its completion. The Analytical Engine, a more ambitious plan, would have done a wide range of calculating tasks. With it, Babbage recognized the need for an input device, memory, a central processing unit, and an output device, and for this he is known as the male parent of Computing.Backus, John W. - Mathematician from Philadelphia who headed the research team at IBM that created FORTRAN, the first machine separatist programming language.-important devices/developmentsFloppy motor - The floppy drive is always called "Drive A". A floppy disk can hold 1.5 megabytes of data. Thats more or less 1,500,000 characters or letters (or about 300,000 words). Thats more than enough space for the textbook of a large book. Pictures, however, take up a great withdraw of room. You could only fit a small number of good-qual ity pictures (or graphics) on a floppy disk. Hard drive - This drive uses disks that are made of atomic number 13 or glass (and therefore catchy). Each disk can gillyflower 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 non 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 overlap board called the motherboard.
