How it is working

Though the computer had been compared to a human brain, it is really still not able to deal with so many things, or so imaginative. It has to be taught to think the way you want it to think. How you want it to think will again depend on watt you want to do with the computer-play games, solve mathematical problems, carry calculations etc. the series of instructions given to a computer, telling it what to do and how to do, is called a` program’. The person, who does this, is called a `programmer’.

Just as we use words, sings and gestures to tell each other what we think for feel, we need an organized system of words, phrases and symbols to talk to the computer and tell it what to do. Such a system is known as ``language’’.

Popular computer languages include the following

*ALGOL: Algorithmic language

*APL: A programming language

*BASIC: Beginner’s all- purpose symbolic instruction code.

*COBOL: Common business oriented language

*FORTRAN: Formula translation

*PASCAL: named after Blaise Pascal (1623- 62), a French philosopher, mathematician and physicist.

One ordinary computer set cost is rupees 20 thousands to above. This rate is high for the Indian people. On that cost buying is not at easy to common people. So system using is very rare. And computer education needs to develop in the poor students.
