HITORY OF COMPUTERS
DEFINATION
The word computer is derived from the word compute. ... So computer is normally described as a calculating device
COMUTER HISTORY AND DEVELOPMENTS
The computer history is divided into three main parts: -
1) The Dark Age
2) The Middle Age
3) The Modern Age
The Dark Age
Initially, people used stones to calculate. ... This machine was also intended to employ several features subsequently used in modern computers, including sequential control, branching, and looping. ...
Mark 1
Howard Aiken and Grace Hopper designed the MARK series of computers at Harvard University. The MARK series of computers began with the Mark I in 1944. ...
From Mark 1 we shift into a new era of Computers. Onwards, we have, instead of AGES; we use GENERATIONS
The First Generation
The First Generation of Computers starts from 1944. All the Computers were bulky, heavy, large, and difficult to maintain and had huge expenses. ... Other important computers of this generation are ENIAC and UNIVAC. All these computers used vacuum tubes in them, which consumed a lot of power and produced a lot of heat.
Although very fast in their time, these computers were very slow to our present standards. ...
Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 50s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors.
