The Basic Parts of a computer & its Function

1. CPU (Central Processing Unit)

The basic processing of a computer begins with memory fetch or read cycle and the memory fetch is routed to the memory unit.

2. KEYBOARD

 


A keyboard is a computer hardware input device. Originally based upon the design of the mechanical typewriter, computer keyboards have evolved with technological advances much as other computer hardware has evolved. 

 3. Mouse 

 

In computing, a mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface.

4. MONITOR




    A computer monitor is a display adapter that displays information processed by the computer's video card. When a video card or graphics card converts binary information from 1s and 0s into images, these images are displayed onto the directly connected monitor.

5. AVR or AUTOMATIC VOLTAGE    REGULATOR

 

 

  The AVR architecture and instruction set is available in a large family of 8-bit devices that come in a variety of packages. AVR-series chips come with as little as 1 Kbyte of Flash program memory, up to 256 Kbytes; 32 bytes to 8 Kbytes of RAM; and up to 20 MHz clock speeds.
