Computer History

Computers were made to do the very tedious computations of everyday life and business. The first calculators performed computations in seconds that would take someone using a slide rule minutes if not hours to do. Calculations for NASA entry and exit trajectories would take days or even weeks to calculate by hand and the first mainframe computers would do the calculations in minutes. "The Father of Computers" Charles Babbage who invented the 1st mechanical Computer.. in 1834 he dreamt of designing mechanical calculating machines....

This is not a question with a simple answer. It partly depends on what you mean by "computer". Many inventors contributed to the history of computers and that a computer is a complex piece of machinery made up of many parts, each of which can be considered a separate invention. Many say the first computer is the "difference engine." The first of these devices was conceived in 1786 by J.H. Müller. It was never built. Difference engines were forgotten and then rediscovered...

The answer to this question depends on your definition of a "computer". The earliest "computers" were mechanical devices used to help people count. The first known counting devices or tools were Tally Sticks from about 35,000 BCE. The abacus was invented, possibly by the Babylonians or the Chinese in about 2400 BCE. The abacus consists of movable counters that can be manipulated to add and subtract. The abacus is still used today for basic arithmetic. As mathematics became more complex, it got harder...

There were many engineering refinements to the laptop concept. Here are some of the significant developments: The "clam shell" design which represents our modern laptop was created in 1979 by William Moggridge (a Briton) for GRiD Systems Corporation. GRiD's Compass Computer entered the market in 1981. GRiD was acquired by Tandy Corporation in 1988. One of the first commercially available laptop computers was invented by Adam Osborne in 1981. It was called the "Osborne I" and cost $1795. It came bundled with $1500...

Buy a: Case Power Supply (Sometimes comes with case) Motherboard Processor/CPU RAM/Memory Hard Drive CD/DVD Drive Peripherals, such mouse, keyboard, and monitor. An Operating System. Such as Windows or Linux. Optional Components: Video Card (For graphic intensive actions. Games and graphic design) Sound Card (Higher quality sound. Home theaters and professional music editing) Other peripherals, like earphones. Before you buy, make sure all parts are compatible. This is a simple summary of what to do, consult the manuals for each part for an in-depth guide. Place power supply into case. Put motherboard in place. Connect necessary...

For a computer to produce useful output its hardware and software must work together. Nothing useful can be done with the hardware on its own, and software cannot be utilized without supporting hardware. To take an analogy, a cassette player and its cassettes purchased from the market are hardware. However, the songs recorded on the cassettes are its software. To listen to a song, that song has to be recorded on one of the cassettes first, which is then mounted on the...

The first computer deliberately designed to be much faster than the fastest computer available was the IBM NORC built for the navy, the first true supercomputer built was the Univac LARC built for LLNL (both LARCs built only had one of two possible CPUs installed), the first supercomputer built in quantity (9) was the IBM 7030 Stretch built for Los Alamos and the NSA, the first mass produced supercomputer was the CDC 6600 (it was also the first RISC architecture computer). Which "first"...

Neumann's architecture is one in which a single memory location (memory address)can be used either to store data or program and not both.for example if locations from 8000 to 8050 are used to store a program then input and output data cannot be in locations from 8000 to 8050.Normally microprocessors follow neumann architecture Whereas in Havard architecture normally followed by microcontrollers,there will be separate data and program memory.Both can have same address,so that if program is from location 8000 to 8050 in program...

It is called a microprocessor because it is the single microchip integrated circuit processor of a microcomputer. The term minicomputer was already taken and referred to small computers whose processor was built of many different microchip integrated circuits. There was never anything called a "miniprocessor" in these computers, just as there was never anything called a "mainframe processor" in the big computers. Note: Some early microprocessors were not single microchips, but were instead a family of related microchips that could be interconnected in a...

A computer tower, also known as a computer case, is the enclosure that holds many components of a personal or office desktop computer. A computer tower can come in a wide variety of shapes and sizes and can also be made from a wide range of materials including steel, plastic, aluminum and more. The sizes of a computer tower range from small mini-towers to medium sized mid-towers and all the way up to full-size towers, depending on what the computer is being...

There were many different attempts to produce a mechanical writing machine, but the first one to be commercially successful was invented by Christopher Latham Sholes (1819-1890). He was an American engineer who, together with SW Soule and G Glidden, invented the first typewriter that was later commercially manufactured by Remington, then a sewing machine company. Their first machine was made in 1866, but the keys jammed easily. To solve this problem they followed the suggestion of a business colleague, James Densmore, who suggested...
