ZI computer
The Z1 was a mechanical computer designed by Konrad Zuse from 1935 to 1936 and built by him from 1936 to 1938. It was a binary electrically driven mechanical calculator with limited programmability, reading instructions from punched tape. The Z1 was the first freely programmable computer in the world which used Boolean logic and binary floating point numbers, however it was unreliable in operation.[1][2] It was completed in 1938 and financed completely from private funds. This computer was dest -
Itroduction of the GUI
In computing, a graphical user interface (GUI,[1] sometimes pronounced "gooey")[2] is a type of interface that allows users to interact with electronic devices through graphical icons and visual indicators such as secondary notation, as opposed to text-based interfaces, typed command labels or text navigation. GUIs were introduced in reaction to the perceived steep learning curve of command-line interfaces (CLIs),[3][4][4] which require commands to be typed on the keyboard. The actions in a GUI -
Univac
J. Presper Eckert and John Mauchly built the ENIAC (Electronic Numerical Integrator and Computer) at the University of Pennsylvania's Moore School of Electrical Engineering between 1943 and 1946. A 1946 patent rights dispute with the university led Eckert and Mauchly to depart the Moore School to form the Electronic Control Company, later renamed Eckert-Mauchly Computer Corporation (EMCC), based in Philadelphia, Pennsylvania. That company first built a computer called BINAC (BINary Automatic Com -
BASIC
BASIC (an acronym for Beginner's All-purpose Symbolic Instruction Code) is a family of general-purpose, high-level programming languages whose design philosophy emphasizes ease of use. In 1964, John G. Kemeny and Thomas E. Kurtz designed the original BASIC language at Dartmouth College in New Hampshire. They wanted to enable students in fields other than science and mathematics to use computers. At the time, nearly all use of computers required writing custom software, which was something only -
Jack Kilby
Jack St. Clair Kilby (November 8, 1923 – June 20, 2005) was an American electrical engineer who took part (along with Robert Noyce) in the realization of the first integrated circuit while working at Texas Instruments (TI) in 1958. He was awarded the Nobel Prize in physics on December 10, 2000.[1] To congratulate him, US President Bill Clinton wrote, "You can take pride in the knowledge that your work will help to improve lives for generations to come."[2] He is also the inventor of the handhel -
Altair computer

Apple II
The Apple II series (trademarked with square brackets as "Apple ][") is a set of home computers, one of the first highly successful mass-produced microcomputer products,[1] designed primarily by Steve Wozniak, manufactured by Apple Computer (now Apple Inc.) and introduced in 1977 with the original Apple II. In terms of ease of use, features and expandability the Apple II was a major technological advancement over its predecessor, the Apple I, a limited-production bare circuit board computer for -
Osborne computer
After Adam Osborne sold his computer book-publishing company to McGraw-Hill in 1979, he decided to sell an inexpensive portable computer with bundled software and hired Lee Felsenstein to design it. The resulting Osborne 1 featured a 5 inch (127 mm) 52-column display, two floppy-disk drives, a Z80 microprocessor, 64k of RAM, and could fit under an airplane seat. It could survive being accidentally dropped and included a bundled software package that included the CP/M operating system, the BASIC -
Mosiac
NCSA Mosaic, or simply Mosaic, is the web browser credited with popularizing the World Wide Web. It was also a client for earlier protocols such as FTP, NNTP, and gopher. The browser was named for its support of multiple internet protocols.[3] Its intuitive interface, reliability, Windows port and simple installation all contributed to its popularity within the web, as well as on Microsoft operating systems.[4] Mosaic was also the first browser to display images inline with text instead of displ -
Eniac
ENIAC (/ˈini.æk/ or /ˈɛni.æk/; Electronic Numerical Integrator And Computer)[1][2][3] was the first electronic general-purpose computer. It was Turing-complete, digital, and capable of being reprogrammed to solve "a large class of numerical problems".[4][5] ENIAC was initially designed to calculate artillery firing tables for the United States Army's Ballistic Research Laboratory.[6][7] When ENIAC was announced in 1946 it was heralded in the press as a "Giant Brain".[8] It had a speed of one th
