Konrad Zuse's Z1 Circa 1938
In 1936, Zuse made a mechanical calculator called the Z1, the first binary computer. Zuse used it to explore several groundbreaking technologies in calculator development: floating-point arithmetic, high-capacity memory and modules or relays operating on the yes/no principle. Zuse's ideas, not fully implemented in the Z1, succeeded more with each Z prototype. In 1939, Zuse completed the Z2, the first fully functioning electro-mechanical computer. Konrad Zuse completed the Z3 in 1941, with recy -
UNIVAC Computer
Input consisted of magnetic tape with a speed of 12,800 characters per second with a read-in speed of 100 inches per second, records at 20 characters per inch, records at 50 characters per inch, card to tape converter 240 cards per minute, 80 column punched card input 120 characters per inch, and punched paper tape to magnetic tape converter 200 characters a second. -
smaller computers
Technology advancements in the 1960's saw the creation of the integrated circuit which contained thousands of transistors and other parts on a silicon chip. This meant that computers could become smaller. During the early 1970's, many different kinds of circuits were available some of which could even hold memory as well as computer logic. This resulted in smaller computers becoming available and the central chip that controlled the computer became known as the microprocessor. -
IBM personal computer
IBM introduced its new revolution in a box, the "Personal Computer" complete with a brand new operating system from Microsoft and a 16-bit computer operating system called MS-DOS 1.0. -
laptops
Laptops were originally considered to be "a small niche market"[2] and were thought suitable mostly for "specialized field applications" such as "the military, the Internal Revenue Service, accountants and sales representatives".[2][3] Battery-powered portable computers had just 2% worldwide market share in 1986[4]. But today, there are already more laptops than desktops in businesses, and laptop are becoming obligatory for student use and more popular for general use.[5] According to a forecast -
computer with internet is everywhere
CERN, a pan European organisation for particle research, publicized the new World Wide Web project. The Web was invented by English scientist Tim Berners-Lee in 1989. -
the newest computers
today desktops and laptops are faster and smaller than the old ones.They are a very important part of our lifes.
