The function of Computer

The computer performs four basic functions which are as follows
1. Input Information or data that is entered into a computer is called input. It sends data and instructions to the Central Processing Unit (CPU).
2. Processing It is the sequence of actions taken on data to convert it into information that is meaningful to the user. It can be calculations, comparisons, or decisions taken by the computer.
3. Output It makes processed data available to the user. It is mainly used to display the desired result to the user as per input instructions.
4. Storage It stores data and programs permanently. It is used to store information during the time of program execution and is possible to get any type of information from it.

🍁 A computer can perform similar operations thousands of times, without becoming bored, tired, or even careless. Secondly, computers can process information at extremely rapid rates.

🍁 For example, modern computers can solve certain classes of arithmetic problems millions of times faster than a skilled mathematician.

🍁 On a typical computer system, cards are read at an average speed of 1000 cards per minute and as many as 1000 lines can be printed at the same rate.

🍁 Finally, a computer, unlike a human being, has no intuition. A person may suddenly find the answer to a problem without working out too many of the details, but a computer can only proceed as it has been programmed to.
