When was computer invented

Because of the versatility of this design, several enterprising individuals designed upgrades that users could add to their model. The IBM was the first, commercially successful, portable computer. The IBM had a bit processor, took quarter-inch cartridge QIC magnetic tape drives and gave users the option to switch the screen between white on black and black on white. It was launched in Japan in and released internationally in It weighed just 1.

It even featured a built-in, calculator-style roll printer. Although maybe a little strange to look at, the first flip-form laptop , was the Dulmont Magnum, released in Australia in — The Dulmont Magnum came with a word processor, spreadsheet, telecommunications, file manager, appointment manager and an 8 x 80 character LCD screen.

Steve Jobs unveiled the first Macintosh in The Macintosh was built without a cooling fan, to keep the computer quite.

However, this caused the computer to overheat, resulting in many component failures. The HP was one of the earliest commercialized touchscreen computers. A series of vertical and horizontal infrared light beams crossed just in front of the screen.

Touching the screen would break the infrared and place the cursor at the desired location. So, who invented computers? Was it Babbage, Turin, Zuse or some ancient civilization? Let me know what you think in the comments below.

Well done article. The design of the Altair was very basic. Username or Email Address. Remember Me. Tech Trends. Rose Barfield , 1 year ago 3 13 min read. On 12 May , Konrad Zuse completed the Z3 in Berlin, which was the first fully functional programmable and automatic digital computer. Just as the Silicon Valley pioneers would later do, Zuse successfully built the Z3 in his home workshop, managing to do so without electronic components, but using telephone relays. On the other side of the war, the Allied powers did attach importance to building electronic computers, using thousands of vacuum tubes.

The first computer that was Turing-complete, and that had those four basic features of our current computers was the ENIAC Electronic Numerical Integrator and Computer , secretly developed by the US army and first put to work at the University of Pennsylvania on 10 December in order to study the feasibility of the hydrogen bomb.

Presper Eckert, occupied m2, weighed 30 tons, consumed kilowatts of electricity and contained some 20, vacuum tubes. ENIAC was soon surpassed by other computers that stored their programs in electronic memories. The vacuum tubes were replaced first by transistors and eventually by microchips, with which the computer miniaturization race commenced. But that giant machine, built by the great winner of the Second World War, launched our digital age.

Nowadays, it would be unanimously considered the first true computer in history if it were not for Konrad Zuse , who decided in to reconstruct his Z3, which had been destroyed by a bombing in The replica was exhibited at the Deutsches Museum in Munich, where it is found today.

Focused on making it work, Zuse was never aware that he had in his hands the first universal computing machine. It depends. The question remains today as open as this one: What makes a machine a computer?

Presper Eckert started to invent the ENIAC, and it was continuing in the development phase but not completed until It used about 18, vacuum tubes and occupied about 1, square feet, weighing almost 50 tons. But, according to the judge ruled, the first digital computer was ABC computer. The first electronically-stored program that was able to electronically store and execute a program written by Kilburn, which can calculate the highest proper factor of an integer with the help of repeated subtraction instead of division.

On 21 June , Kilburn's program was executed. It performed its first calculation on 6 May It was designed with an implementation of tic-tac-toe screened on a 6-inch cathode ray tube. Another computer, Manchester Mark 1, was able to run stored programs. Also, at the Victoria University of Manchester, the first version of the Mark 1 computer was built in April that was able to run the program.

Later, it was used to run a program for nine hours without error to search for Mersenne primes on 16 and 17 June. The Z4 was the first commercial computer developed by Konrad Zuse in In , the first computer company was founded by John Mauchly and J. Presper Eckert, which was the Electronic Controls Company. Furthermore, the first commercial scientific computer was introduced by IBM to publicly on 7 April It was a revolutionary computer.

In , demonstrated at the Massachusetts Institute of Technology, there was a computer invented, which was TX-0 Transistorized Experimental computer and considered the first transistorized computer. It was the first minicomputer. Olivetti manufactured the Programm that was invented by Pier Giorgio Perotto at the New York World's Fair in ; it was the first desktop computer introduced to the public.

The first mass-marketed desktop computer was considered the HP A computer that began marketing by Hewlett Packard. The Xerox Alto is considered to be the first workstation that was introduced in For its time, it was an innovative computer that contained a fully functional computer, mouse, and screen or a display. The computer worked like most computers today that uses icons and menus, windows as an interface for its operating system.

On 9 December , Douglas Engelbart demonstrated the different functionalities of a computer's in Mother of All Demos. Additionally, the Xerox Alto computer was never sold. Also, on 15 November , the first microprocessor , Intel , was introduced by Intel. In , the term "personal computer" was created when Ed Roberts introduced the Altair The computer took input and produced output data on the basis of the series of switches with the help of turning on and off a series of lights.

In , Konrad Zuse began working on the Z4 that later became the first commercial computer. On April 7, , IBM publicly introduced the , its first commercial scientific computer.

MIT introduces the Whirlwind machine on March 8, , a revolutionary computer that was the first digital computer with magnetic core RAM and real-time graphics. The TX-0 Transistorized Experimental computer is the first transistorized computer to be demonstrated at the Massachusetts Institute of Technology in In , the first desktop computer, the Programma , was unveiled to the public at the New York World's Fair.

It was invented by Pier Giorgio Perotto and manufactured by Olivetti. In , Hewlett Packard began marketing the HP A , considered to be the first mass-marketed desktop computer. Although it was never sold, the first workstation is considered to be the Xerox Alto , introduced in The computer was revolutionary for its time and included a fully functional computer, display, and mouse.

The computer operated like many computers today utilizing windows , menus , and icons as an interface to its operating system. Intel introduces the first microprocessor, the Intel , on November 15, Considered as the first microcomputer, it used the Intel processor and was the first commercial non-assembly computer. In , Ed Roberts coined the term "personal computer" when he introduced the Altair The computer relied on a series of switches for inputting data and output data by turning on and off a series of lights.

The IBM is the first portable computer, which was released in September The computer weighed pounds and had a five-inch CRT display, tape drive , 1. The first truly portable computer or laptop is considered to be the Osborne I , which was released in April and developed by Adam Osborne. The Osborne I weighed The computer kit was developed by Steve Wozniak in and contained a 8-bit processor and 4 kb of memory, which was expandable to 8 or 48 kb using expansion cards.

Although the Apple I had a fully assembled circuit board, the kit required a power supply , display , keyboard , and case to be operational. Below is a picture of an Apple I from an advertisement by Apple.

The computer was code-named Acorn. When was the first computer invented? Note Early inventions that lead up to the computer, such as the abacus , astrolabe, slide rule , clocks, calculator , and tablet machines, are not accounted for on this page.
