Who invented computers when

For the first time, non-geeks could write programs and make a computer do what they wished. It offers color graphics and incorporates an audio cassette drive for storage. I was the technical brains — I figured out how to do it, and did it, and documented it.

It has an Intel chip, two floppy disks and an optional color monitor. It also popularizes the term PC. It also features a drop-down menu and icons. It flops but eventually evolves into the Macintosh. The Gavilan SC is the first portable computer with the familiar flip form factor and the first to be marketed as a "laptop. This was the company's response to Apple's GUI. Commodore unveils the Amiga , which features advanced audio and video capabilities.

More than two years later, only dot-coms had been registered. Its bit architecture provides as speed comparable to mainframes. Facebook, a social networking site, launches. Charles Babbage created the concept of a programmable computer. Charles Babbage and the Analytical Engine " ".

The first section consists of a series of cogs and gears designed to add up as a replacement for inefficient figure tables. Six sections of the machine have survived. The Programmer and the Prophet. The first computer that resembled the modern machines we see today was invented by Charles Babbage between and He developed a device, the analytical engine, and worked on it for nearly 40 years. It was a mechanical computer that was powerful enough to perform simple calculations.

Is the abacus the first computer? No, but it is the first-known calculating device. The abacus was first used in B. An abacus consists of a rectangular frame containing thin parallel rods attached with beads for counting. Who invented the laptop? Adam Osborne built the first laptop in and named it "Osborne 1. What is the first modern computer in the world? Since it was the first computer to use electronic technology, it was nearly 1, times faster than previous computers.

It weighed nearly 50 tons as it used 18, vacuum tubes. Sources "Analytical Engine. Computer History Museum, online exhibit. September George, Aleta. April 2, May Park, Edwards. February Like so many early computer scientists he struggled to get the funding he needed.

Note: The Colossus computer is not to be confused with the Bombe: an electromechanical device, also designed by Turing and used to decode Enigma, in His work did not stop at the end of WW2!

After the war, he worked at Manchester University where he played a key role in developing early computing technology and wrote several papers, that still define the way with think about computer science to this day. Although he might not be the man who invented computers, Turin is certainly the man who invented computer science! It lacked many of the functionalities of modern computers; it was designed for one specialist task and was not Turing complete.

It was fully reprogrammable and so, able to solve a complex number of problems. It could take several days to program because it was programmed via external switches and dials. The ENIAC took 20 seconds to complete its first calculation, a mechanical computer of the time would have taken 40 hours.

By the time it was decommissioned, in , it had been used to solve problems as diverse as wind tunnels, random number generators, and weather prediction.

The ENIAC contained 20, vacuum tubes, 7, crystal diodes, 1, relays, 70, resistors, 10, capacitors and 5,, hand-soldered joints. It was 2. The ENIAC consumed a staggering kW of electricity, which led to a rumor that whenever it was switched on, lights dimmed in Philadelphia. Several tubes needed replacing every day. Although relatively simplistic to other computers of the time, it was the first computer to store its program digitally not via wires and switches. Like the Machester Baby, it also used a stored program.

However, it did not run exclusively on transistors and contained several tubes in its clock. It was not, a commercial success. The computer was so successful that the company had to hire extra staff just to keep up with demand!

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.
