IMPORTANCE OF COMPUTER
Sumedha College
Let lsquo S We Identify The Main Parts Of The Computer
Monitor
Keyboard
System Unit
Mouse
We call this ldquo computer System rdquo
Let lsquo S We Know about Significant Features of Computer
1 High Speed and Efficiency
10487071048707 A computer functions at a very high speed Therefore it is capable of
performing a large number of operationscalculations within a short period
2 Accuracy
10487071048707 In addition to being very fast computers are very accurate
10487071048707 The calculations are 100 error free
3 Reliability
A computer is a reliable machine Breakdowns are very rare so that the
user can depend on it
Modern electronic components have long lives
4 Cost
Although the initial cost to purchase a computer is relatively high the long
term operational cost is low compared to the cost for the same activity done
manually by humans
5 Capacity of Storage
A computer has much more storage capacity than the capacity of human
beings to memorize
It can store a large amount of data
It can store different types of data such as images videos text audio etc
What is Embedded Computers
Devices with computers to perform s specific task
are called embedded devices Some of them are
Mobile Phones
Modern Televisions
Washing Machines
Automobiles
BASIC FUNCTION OF COMPUTER
THESE COMPUTER COMPONENTS DIVIDED 4 MAIN PARTS
1Input Devices
2Output Devices
3Storage Devices
4Communication Devices
Input Devices
The devices which are used to enter data and instructions to
computers are called input devices
Output Devices
The devices which are used to retrieve the data and
information are called output devices
Communication Devices
The devices which are used to exchange the processed data
and information are called communication devices
Storage Devices
The devices which are used to store data information and
instructions are called storage devices
Central Processing Unit
Central Processing Unit (CPU) is the brain of the computer
Central Processing Unit processes data in the computer and
converts them into information
Main Memory
The device which is used to store data information and instructions temporarily is identified as the main memory or the primary memory It is also called the Random Access Memory (RAM)
COMPUTER HARDWARE All the things that you can touch in the computer are called hardware
COMPUTER SOFTWARE Things that can not touch such as programmes with data and instruction are called
computer software
