Telex messaging network invented by Germany
During the world war, two german scientists decided to make a messaging network system to communicate with different parts of the battle field -
Model K. Adder
George Stibitz built the Model K. Adder in 1936. He named it "Model K.", because he built it on a kitchen table. He also named it "Adder" because it could only add, not subtract or anything else. To make it, he used strips of metal from tin cans and, some old relays from Bell Lamps. It could add two binary digits. It also showed proof of concept for applying Boolean logic to the design of computers resulting in construction of the relay-based Model I Complex Calculator in 1939. -
Bombe
Bombe was a machine that decrypted Nazi ENIGMA-based Military comunications during World War 2. The British Bombe is conceived of by computer pioneer Alan Turing and Harold Keen of the British Tabulating Machine Company. -
ENIAC
ENIAC was built by John Mauchly and J. Presper Eckert. Because of its electronic, as opposed to electromechanical, technology, it is over 1,000 times faster than any previous computer. ENIAC occupied more than 1,000 square feet, used about 18,000 vacuum tubes and weighed 30 tons. -
Harvard Mark 1
Conceived by Harvard physics professor Howard Aiken, and designed and built by IBM, the Harvard Mark 1 is a room-sized, relay-based calculator. The machine had a fifty-foot long camshaft running the length of machine that synchronized the machine’s thousands of component parts and used 3,500 relays. The machine could produce mathematical tables but soon was superseded by other electronic stored program computers. -
Early Transistorized Computer
Richard Grimsdale and Douglous Webb demonstrate a prototype transistorized computer. The machine used 550 diodes and 92 point-contact transistors. -
DEC PDP-1
A DEC PDP-1 would have cathode ray tube graphic display, paper tape input/output, needs no air conditioning and requires only one operator; all of which become standards for minicomputers. Its large scope intrigued early hackers at MIT, who wrote the first computerized video game,SpaceWar!, as well as programs to play music. More than 50 PDP-1s were sold. -
Xerox PARC Alto
The Alto was a computer that had a massive influence on the computer industry.It was based on a graphical user interface using windows, icons, and a mouse, and worked together with other Altos over a local area network. It could also share files and print out documents on an advanced Xerox laser printer. The applications were also very innovative. It had a word processor known as 'Bravo', A graphics editor and email. It was the inspiration for the apple Lisa and Macintosh computers -
Tandem-16
The Tandem-16 was built in 1975. The Tandem-16 is one of the first commercial fault-tolerant computers. The banking industry immediately rushed to have the machine. The Tandem-16 eventually to the "Non-stop" series of machines, which were used for early ATMs and to monitor stock trades. -
Sony Playstation
Sony decided to enter the gaming industry in 1994 with the release of the Sony Playstation in Japan, and in the US a few months later. This was originally a disc-based gaming console that started as a collaboration between Sony and Nintendo to create a CD-ROM-based version of Nintendo's gaming system. Sony continued with the gaming system, and eventually settling on a system that would support games, as well as audio CD playback. Playstation was a massive success,selling more than 100000000units
