HISTORY OF THE COMPTUER

First Digital Computer

Short for Atanasoff-Berry Computer, the ABC started by Professor John Vincent Atanasoff and graduate student Cliff Berry will be developed in 1937 and until 1942 at the Iowa State College (now Iowa State University) developed. The ABC was an electrical machine, the vacuum tubes used for digital computation, including binary math and Boolean logic, and had no CPU. On 19 October 1973, signed by the U.S. Federal Judge Earl R. Larson's decision that the ENIAC patent by Eckert and Mauchly was invalid and named Atanasoff the inventor of the electronic digital computer.
The ENIAC was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was only completed in 1946. It employs an approximately 800 square meters and employed about 18,000 vacuum tubes, very, weighing 50 tons. Although the judge ruled that the ABC computer was the first digital computer, to think much about the ENIAC, be the first digital computer, because it was fully operational.

First Stored Program Computer

The early British computer EDSAC is known as a thought about it, up to the first electronic stored program computer to be. The computer performed its first calculation on 6 May 1949 and was the computer that ran the first graphical computer game.

First Computer Company

The first computer was the Electronic Controls Company and Company was founded in 1949 by J. Presper Eckert and John Mauchly, the same people who helped create the ENIAC computer set up. The company was later renamed EMCC or Eckert-Mauchly Computer Corporation and published a series of mainframe computers under the UNIVAC name.

First commercial computer

In 1942, Konrad Zuse began work on the Z4, which later became the first commercial computer, having to be a mathematician to Edward Stiefel from the ETH Zurich 12th of Expertise Sold in July 1950.

The first PC (IBM compatible) computer

On 7 April 1953 IBM introduced the 701 public, the first electric machine and first produced in series computer. Later IBM introduced its first personal computer called the IBM PC in 1981. The computer was code-named, and sometimes even more often than the glans and had an 8088 processor, 16 MB memory, expandable to 256 and had the use of MS-​​DOS.

The first computer with RAM

MIT is the vortex wind machine on 8 March 1955, a revolutionary computer, the first digital computer was using nuclear magnetic RAM and real-time graphics.

first transistor computer

The TX-O (Transistorized Experimental computer) is the first solid-state computer to be demonstrated at the Massachusetts Institute of know-how in the year 1956.

First Workstation

Although never sold the first workstation is designed, the Xerox Alto, introduced in 1974. The computer was revolutionary for its time and included a fully functional computer, monitor, and mouse. The computer, as much use of computers today run windows, menus and icons as an interface to the operating technique.

First Microprocessor
Intel Invents the first microprocessor, the Intel 4004 on November 15, 1971.

First Personal Computer
The Micral pleased to be on the first, intended for non-commercial computer assembly. The computer uses the Intel 8008 processor and sells for $ 1,750 in 1973.

In 1975, Ed Roberts coined the term personal computer when they introduced the Altair 8800. Although the first personal computer is introduced through a lot to the Kenback-1, for the first $ 750 in 1971, thought to be. The computer, relying on a series of switches for the input of knowledge and knowledge output by a series of on & off lights.

First Laptop or Portable Computer
The first truly portable computer or laptop computer is being given to the Osborne I, which was itself released on April 1981. The Osborne I was a time of Adam Osborne weighed 24 pounds and developed, had a 5-inch display, 64 MB memory, five 1/4 "floppy drives, and a modem.

The IBM Personal Computing Division (PCD), the IBM portable set in 1984, it is the first portable computer, which weighed in at 30 pounds. Later in 1986, IBM announced PCD, it is first laptop computer, the PC Convertible, weighing 12 pounds. Finally, in 1994, IBM introduced the IBM ThinkPad 775CD, the first laptop with a built-in CD-ROM.

First Apple computer
Steve Wozniak Introduces the first Apple known as the Apple I computer in 1976.

First PC Clone

The Compaq Portable is thought about, to be the first PC clone and was published in March 1983 by Compaq. The Compaq Portable was 100% compatible with IBM computers and was developed with any applications for IBM computers.

First Multimedia Computer

In 1992, Tandy Radio Shack is one of the first companies to a computer on the MPC standard with the introduction of the XL M2500 / M4020 SX 2 & Computers release.
