What Is Computer ?
The word computer has been derived from Latin language. A computer is an electronic device that manipulates information or data according to the set of instructions. It has the ability to store, retrieve and process data. A computer is used to type documents, send E-mails and browse the Internet. It is also used to handle accounting, database management, presentations, games and so on.
Functioning of a Computer :
- Input Information or data that is entered into a computer is called input. It sends data and
instructions to the Central Processing Unit (CPU). - Processing It is the sequence of actions taken on data to convert it into information which is meaningful to the user. It can be calculations, comparisons or decisions taken by the computer.
- 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.
- Storage It stores data and programs permanently. It is used to store information during the time of program execution and possible to get any type of information from it.
Features of Computer :
- Speed The computer can process data very fast at the rate of millions of instructions per second.
- Accuracy Computers provide a high degree of accuracy. They respond to the user as per the input instructions.
- Storage Capacity Computers are capable to store huge amount of data which depends on the capacity of hard disk.
- Versatility Computers can do different types of work simultaneously. They can perform multiple tasks at a same time.
