Created by German Konrad Zuse between 1936 and 1938, Considered to be the first electro-mechanical binary programmable computer, with a 64-word memory and a clock speed of 1 Hz. It read instructions from punched tape. This computer was destroyed during World War II, along with all construction plans.
-
Developed by Tommy Flowers, created to help the British code breakers read encrypted German messages during the World War II. It had an optical reader that could read data at a speed of 5000 characters per second.
-
Invented by J. Presper Eckert and John Mauchly. They began designing the computer in 1943 but was not finished until 1946. It took a lot of space - about 1,800 square feet and weighted almost 50 tons. The military used the ENIAC to perform calculations for the design of a hydrogen bomb, weather predictions as well as wind-tunnel design.
-
Considered to be the first computer capable of storing and running a program from memory. This computer could installed at a distant site - away from its place of manufacturing, and its architecture was used as the basis for several machines into the 1960's.
-
Developed at MIT by Jay Forrester when trying to develop a universal flight trainer that would simulate flight during World War II. Late in 1951, the Whirlwind computer was operational and made available for scientific and military research.
-
Considered to be IBM's first electric computer and the first mass produced computer. It had 256 40-bit words of main memory and could perform 2,200 multiplications per second. Programs could be stored in an internal electronic memory.
-
Developed by Ted Hoff and Masatoshi Shima, it was the first processor with a 4-bit register and a clock speed of 740 kHz. This processor was smaller than a human thumbnail and had 2,300 transistors with 10-micron spacing. The price for it was $200.00, and could possess as much computing power as the ENIAC computer.
-
Developed by Steve Wozniak, this computer contained a 6502 8-bit processor and 4 KB of memory, and could be expandable to 8 or 48 KB using expansion cards. The Apple I required a power supply, display, keyboard, and case to be operational. The computers were first sold for R$666.66.
-
This personal computer had a code name "Acorn" and ran on a 4.77 MHz Intel 8088 microprocessor and was equipped with 16 KB of memory, which could expand to 256 KB. The PC also came with an optional color monitor.
-
USB - Universal Serial Bus, also known as thumb drive, flash drive, pen drive, memory stick, etc. was first patented by a company called M-Systems as well as IBM Late in 2000, IBM sold the first USB flash drive. The drive held 8 megabytes and in less than 10 years, its capacity increased to 256 gigabytes per drive. The USB is used for storing, transferring and copying data.
