WHAT IS A COMPUTER
The word "COMPUTER" is derived from the word "COMPUTE" which means "to calculate". Computer is an electronic machine that can perform arithmetical operations at higher speed and accuracy. It is a device that processes the instructions supplied as input. It produces the actual result as output in a few seconds according to the given data or instructions (i.e. program or software).
According to Oxford dictionary "An electronic machine that can store, find and arrange information, calculate amounts and control other machines."
The computer remembers the data or instructions. It does the processing when asked to. It also gives the results in the specified form. A computer can store a series of instructions and a large amount of the data in its memory. Not only this, but it can also process a complete job for its users
Basically, computer works on three well defined steps:
1. Accepting input,
2. Processing arithmetical and logical operations, and
3. Producing output.
In other words, we can say that computer accepts data as input. It produces the results as output. Thus, a computer processes input to create output. A computer can also store the information as results for future use.
