Computer

Computer is the Machine which is used to calculate; count and estimate. it is called computer in speaking and writing. It is called (Arabic: کميوتر اور حاصوب, Persian: کامپیوٹر اور رایانہ, French: Ordinateur, English: computer, سونسکا: Dator). Computer is electronic device which is used to answer the questions like to calculate and solve the long estimate.  In the particular time and In accordance with prescribed and provided instructions very easily.  And then it either shows it or save in it. Now a day’s computer is use for the common problems in daily life which is depends on based on the microprocessor. Here mean of common problems Computers are used in various devices of life because today computer is only not a personal device but it use in different places for different purpose like in offices, homes and other works.

Definition

Computer: as we discussed above that Computer is electronic device which is used to answer the questions like to calculate and solve the long estimate.  In the particular time and In accordance with prescribed and provided instructions very easily. And then it either shows it or save the data in it.

Introduction

Computer is derived for Greek letter which mean is to compute or to calculate. In past this word is used for Calculator but now it is used for The term machine means a device.  This stores the information in it and later analyze them according to a set strategy. In other words it mean is that generally computer cannot do anything Rather it Have to tell and explain that how to work according to our instruction. Computer stores our instruction or information and interconnected and cohesive. The difference between calculator and the computer is that computer Complex computers can store programs within themselves and this feature enables them to perform logical analysis without human assistance.

Ideal computer components

In an ideal computer there are a lot of parts which is consisting in two types for explain other. For example by In terms of structure and in terms of actions. They are the two types by which any person can understand the parts of an ideal computer so we named the parts of computer below.

In terms of structure 

In the terms of structure the parts of computer divide in two types the external components and internal component.

External components:

1) Monitor

2) Case

3) Keyboard

4) Mouse

Internal component:

1) Motherboard

2) Processor

3) Memory

4) Graphics card

5) Video cards

6) Hard drive

7) Compact disc

8) RAM-DVD

In terms of functions:

Thus the parts of a computer through which it performs its functions are all the components that are present in a computer. But basically it can be said that the most important functional parts of a computer are those through which the central operating unit (CPU) performs its functions internally and can access the memory address. These active ingredients can be divided into three major groups.

1) Instruction set architecture

2) Micro architecture

3) System design

The history of computer

About any device we cannot say that it is computer because the definition of the computer changes with the changes in time so we cannot say any device as the first computer. The devices which were called first as a computer but now they do not called computer. Originally a computer term was for a person who could calculate or do estimate of anything He did this with the help of some mathematical invention like calculator or some other basic measuring instrument.

Some mechanical inventions have also been used which can be said to be the most primitive form of computer or its development but they cannot be considered as computer by today's definition because they lacked any programmable style. ۔ Examples include abacus, slide rule, astrolabe, antikythera mechanism and various instruments made by Muslim scientists (see Muslim Scientist).
