information on the four generations of computering

the first generation of computering

the beginning of commercial computer age is from UNIVAC (universal automatic computer). it was developed by two scientists mauchly and echert at the census department of united states in 1947 the first generation computers were used during 1942-1955 they were based on vacuum tubes Examples of the first generation computers are ENIVAC and UNIVAC-1

ADVANTAGES

vacuum tubes were the only electronic component available during those days

vacuum tube technology made possible to make electronic digital computers

these computers could calculate data in millisecond

DISADVANTAGES

the computers were very large in size

they consumed a large amount of energy

they heated very soon due to thousands of vacuum tubes

they were not very reliable

input and output devices

motor-is an output device because it shows you what you what to see

mouse-is an input device because you click what you what to see

camera-is an input device because you are putting things into it

printer-is an output device because you taking something of the computer and putting on paper
