A computer ЁЯЦе is an electronic machine which stores, reads and processes data to produce meaningful information as output.
Components of Computer:-
- Input Unit- Devices used to give instructions, e.g., Keyboard, mouse, joystick, optical character reader, CDs, Bar code reader, Touch screen, Light Pen, Scanner, Magnetic Ink Character Recognition(MICR), etc.
- Central Processing Unit- (CPU) is the device for the manipulation of information inside the computer ЁЯЦе. CPU is known as the brain ЁЯза of the computer, but commonly called a processor and has the following components.
- Arithmetic Logic Unit -(ALU) performs all the logical and arithmetical operations.
- Control Unit- (CU) instructs, maintains and controls the flow of information.
- Output Unit:- is the device to display the result of processing, e.g., Visual Display Unit, Printer, Monitor, Speaker, Pen Drive, etc.
- Thus we know that when we study ЁЯУЦ ЁЯУУ the basics about computer ЁЯЦе then we understand the things properly.
