Basics of Computers
Dr. Rohit Bagthariya

Computer
A computer is an electronic device, operating under
the control of instructions stored in its own memory
that can accept data (input), process the data
according to specified rules, produce information
(output), and store the information for future use.

Functions of a computer
Click on the model to interact
Any digital computer carries out five functions in gross terms:
 Takes data as input.
 Stores the data in its memory and use them when
required.
 Process the data and converts it into useful information
 Generates the output.
 Control all the above four points.

Computer Components
Any kind of computers consists of HARDWARE and SOFTWARE.

Hardware
The physical parts/components of a computer that we can touch,
for example, monitor, mouse, keyboard, computer data storage,
hard drive disk (HDD), system unit (graphic cards, sound cards,
memory, motherboard and chips), etc.
Hardware can be further classified into,
 Input devices
 Output devices
 Processing devices
 Memory devices

Software
Software is a generic term for organized collections of computer
data and instructions, often broken into two major categories:
system software that provides the basic non-task-specific
functions of the computer, and application software which is
used by users to accomplish specific tasks.
Software falls into two broad categories,
 System Software
 Application Software

Characteristics of Computer
 The computer can process data very fast, at the
rate of millions of instructions per second.
Some calculations that would have taken hours
and days to complete otherwise, can be
completed in a few seconds using the computer.
For example, calculation and generation of
salary slips of thousands of employees of an
organization, weather forecasting that requires
analysis of a large amount of data related to
temperature, pressure and humidity of various
places, etc.

Versatility

 Computer provides a high degree of
accuracy. For example, the computer
can accurately give the result of
division of any two numbers up to 10
decimal places.

Versatility

 When used for a longer period of time,
the computer does not get tired or
fatigued. It can perform long and
complex calculations with the same
speed and accuracy from the start till
the end.

Diligence
Storage
Versatility

 Large volumes of data and information
can be stored in the computer and also
retrieved whenever required. A limited
amount of data can be stored,
temporarily, in the primary memory.
Secondary storage devices like floppy
disk and compact disk can store a large
amount of data permanently.
Speed
Accuracy
Diligence
Storage
Versatility

 Computer is versatile in nature. It can
perform different types of tasks with
the same ease. At one moment you can
use the computer to prepare a letter
document and in the next moment you
may play music or print a document.
Computers have several limitations too.
Computer can only perform tasks that it
has been programmed to do.
