Early Comuters Abacus is also called a counting frame that was used for 100 s of years before calculators came in. This is still used in some parts of Asia and Africa It was the first calculator that could only a certain amount of numbers It was the first automatic calculator. It was able to calculate formulas but weighed five tons. In 1885 he built a much more efficient calculator that used traditional hand methods
First generation of computers (1941 -1956) The worlds first digital calculator. Colossus The worlds first digital programmable computer. ENIAC was the first electronic general-purpose computer. The first commercially successful computer, introduced in 1951 by Remington Rand. UNIVAC
Second generation computer (1956 -1963) TRADIC TX-0 Computer Transistor Digital Computer or Transistorized Airborne Digital Computer This computer was a high speed computer used for experiments The second generation The mainframe was made of transistors and the size was greatly reduced. The first generation The computers were very big and was mainly used for calculating numerical.
Third-Generation Computers (1964 – 1971) the third generation The second generation The mainframe was based on a small scale called IC The computers were able to multi task The mainframe was made of transistors and the size was greatly reduced.
The 4 th generation The intel 2004 chip located all the central processes unit and memory to input and output controls. The 4 th generation vs The third generation The mainframe was based on a small scale called IC The computers were able to multi task
5 th generation Phones have a touch screen which gives the user much more movement with the phone/computer. The size also has been greatly reduced to make in portable. generation
