Introduction

Computer is certainly the most marvelous tool ever invented by human. It is a very useful tool that is being employer in almost all steps of mankind and evolved to this stage over past few decades. Know I will tell you what the parts of it are and how to use them. This guide is for absolute beginners.

Lets begin with basic parts of computer

1. Monitor which displays the result.

2.  Cpu which is the brain of computer.

3. Keyboard through which type the data.

4. Mouse is one of the primary input devices.

Monitor, keyboard, mouse are common things which we know how to use. so I will tell about parts in cpu.

1.) Hard disk drive

The data we enter or save any document will be stored in hard disk drive (HDD).

This drive is usually located inside the computer. The HDD serves as a computer's main source of storage. Media files, documents, games and entire operating systems can be called up at will from the HDD. HDDs come in a wide range of speeds, sizes and portability to give the user flexibility in terms of storage needs.

 

It will be available in market from 160 GB, 320 GB, 500 GB, 620 GB, 1 TB, 1.5 TB, 2TB……………so on.

2.)  Processor

A processor, or central processing unit (CPU), is commonly referred to as the "brain" of a computer. The CPU carries out computer functions, determines how fast the computer runs and makes sure the computer is functioning properly. The CPU is considered the most important part of the computer because without it your computer would not function.

 
3.) Ram (random access memory)
RAM, short for Random Access Memory, is the temporary storage space within a computer that helps it operate more efficiently by holding data for the processor. RAM will store files as long as a computer is turned on; once the power is cut, the RAM is wiped clean, leaving it ready for the next time you turn on the computer. There are several types of RAM currently on the market, each with unique attributes.

4.) Motherboard
Central processing unit (CPU) chip, read only memory (ROM), random access memory (RAM), other major functional elements, and (in PCs) the basic input output system (BIOS). It usually also has sockets

into which other circuits boards, such as for communication ports and peripheral devices, can be plugged in. it is the main device in cpu which connects all other parts.

5.) Smps

Switching-mode power supply. Simply we can say it supplies power to all parts of cpu.
