Memory
C Language

Computer memory is the storage space in the computer,where data is to be processed and instructions required for processing are stored. The memory is divided into large number of small parts called cells. Each location or cell has a unique address, which varies from zero to memory size minus one.

Storage
C Language

Memory unit is the amount of data that can be stored in the storage unit. This storage capacity is expressed in terms of Bytes.

Processor
C Language

Central Processing Unit (CPU) consists of the following features. CPU is considered as the brain of the computer. CPU performs all types of data processing operations. It stores data, intermediate results, and instructions (program). It controls the operation of all parts of the computer.

Following are some of the important input devices which are used in a computer. Ex:- Keyboard, Mouse, Joy Stick, Light pen, Track Ball, Scanner, Graphic Tablet, Microphone, Magnetic Ink Card Reader(MICR), Optical Character Reader(OCR), Bar Code Reader, Optical Mark Reader(OMR)
