The history of computers in education
has been variously characterized as an
"accidental revolution" or "unthinking
man and his thinking machines”.
Others have said that the computer
revolution has changed the adage
that "necessity is the mother of
invention" to "in a computer world,
invention is the mother of necessity."
However characterized, it is clear that
innovators in this field have created
some of the most provocative and
stimulating ideas in the history of
In retrospect, there has been a confluence of
changes that have significantly impacted the
direction of modern education.

•An input device is any device that
provides input to a computer.
Most common and very popular input device is
keyboard. The keyboard helps in inputting the data to
the computer. The layout of the keyboard is like that

additional keys provided for performing some
Mouse is most popular Pointing device. It is a very
famous cursor-control device. It is a small palm size
box with a round ball at its base which senses the
movement of mouse and sends corresponding
signals to CPU on pressing the buttons.
Joystick is also a pointing device which is used to
move cursor position on a monitor screen. It is a stick
having a spherical ball at its both lower and upper
ends. The lower spherical ball moves in a socket. The
Joystick can be moved in all four directions.

pen. It is used to select a displayed menu item or
draw pictures on the monitor screen. It consists of a
photocell and an optical system placed in a small

photocopy machine. It is used when some
information is available on a paper and it is to be
transferred to the hard disc of the computer for
Microphone is an input device to input sound that is
then stored in digital form. The microphone is used for
various applications like adding sound to a
multimedia presentation or for mixing music.
•Bar Code Readers
Reader is a device used for reading bar coded data
(data in form of light and dark lines). Bar coded data
is generally used in labeling goods, numbering the
books etc. It may be a hand held scanner or may be

part of a desktop computer. It
includes the motherboard, CPU,
RAM, and other components. The
system unit also includes the
case that houses the internal
components of the computer.
Stands for "Central Processing Unit." This
is the pretty much the brain of your

basic instructions to complex functions. Any
time something needs to be computed, it
gets sent to the CPU.
•CPU itself has following

•A RAM constitutes the internal
memory of the CPU for storing
data, program and program result.
It is read/write memory. It is called
random access memory (RAM).
•The motherboard serves as a
single platform to connect all of
the parts of a computer together. A
motherboard connects CPU,

•Linux (pronounce LINN-ux) is a family of open
source operating systems, which means that they can
be modified and distributed by anyone around the world.
This is very different from proprietary software like
Windows, which can only be modified by the company

it is free, and there are many different distributions (or
versions) that you can choose from. Each distribution
has a different look and feel, and the most popular ones
include Ubuntu, Mint, and Fedora.
