Emergence of IT Era
 

By the late 1990s fifth generation computers were build and they became much more personal and prices became low that everyone can own a computer. Since then computer applications used in every field. The evolution of Internet made a rapid growth in computer applications and became a part of daily life dealing with education, health, business, transport and agriculture etc.





Computers between 1943 and 1959 usually regarded as 'first generation' and are based on valves and wire circuits. The are characterised by the use of punched cards and vacuum valves. All programming was done in machine code. They were mainly used for scientific purposes. In 1953 there were 100 computers in the world.

Computers built between 1959 and 1964 are often regarded as 'Second Generation' computers, based on transistors and printed circuits - resulting in much smaller computers. More powerful, the second generation of computers could handle interpreters such as FORTRAN (for science) or COBOL (for business), that accepting English-like commands, and so were much more flexible in their applications. Hence the uses of computers grew rapidly due to their applications in business and science.




Computers built between 1964 and 1972 are often regarded as 'Third Generation' computers, they are based on the first integrated circuits - creating even smaller machines. Typical of such machines was the IBM 360 series mainframe, while smaller minicomputers began to open up computing to smaller businesses. Banks begin to computerise hence business improved.




Computers built after 1972 are often called 'fourth generation' computers. They are based microprocessors. This made spread of computers high and cost reduced.
