Generation of Computers

Developments over the years have resulted in machines with greatly increased speeds, storage or memory, and computing power. These developments were so far-reaching and numerous that they are generally categorized by generations. Each generation is initiated by significant advances in computer hardware or computer software that run the machines.


The development of electronic computers can be divided into five (05)  generations depending upon the technologies used. The main five generations of computers are:
First Generation (1942-1955 : Vacuum tube based)Second Generation (1955-1964 : Transistor based)Third Generation (1964-1975 : Integrated Circuit based)Fourth Generation (1975-Present : VLSI microprocessor based)Fifth Generation (Present & Beyond : ULSI microprocessor based)

Different devices and tools have been employed in calculation and processing of data. An ancient calculating device is the abacus, a mechanical calculating device first used around 2500 B.C. to add and subtract.

John Napier, a Scottish mathematician, developed (about 1610) a series of rods made of bones (commonly called Napier's bones) that could be arranged to produce the products of selected numbers. He used these rods to produce the first table of logarithms. In 1865 the French mathematician Blasé Pascal improved on this concept and produced a mechanical calculator called Pascaline. It was more compact and easier to use than Napier's bones. The Pascaline was capable of performing addition and subtraction. All attempts to produce a calculator capable of performing all the four arithmetic operations and producing mathematical tables quickly and accurately were not successful until 1820. Thomas de …
