FUNDAMENTALS OF COMPUTER

A computer can store, process & retrieve data as and when we desired.
The fact that computer process data is so fundamental that many people
have started calling as “Data Processor”.
A computer first it gets the Data, does Process on it and then produces
Information.
DATA PROCESS INFORMATION
Today’s world is an information-rich world and it has become a
necessity for everyone to know about computers.

FUNCTIONALITIES OF A COMPUTER
If we look at it in a very broad sense, any digital computer carries
out the following five functions:
Step 1 - Takes data as input.
Step 2 - Stores the data/instructions in its memory and uses them
as required.
Step 3 - Processes the data and converts it into useful information.
Step 4 - Generates the output.
Step 5 - Controls all the above four steps.

Computer Fundamentals ─ Components
All types of computers follow the same basic logical structure and perform the
following five basic operations for converting raw input data into information
useful to their users.

Input Unit
This unit contains devices with the help of which we enter data into the
computer. This unit creates a link between the user and the computer.
The input devices translate the information into a form understandable
by the computer.
CPU (Central Processing Unit)
CPU is considered as the brain of the computer. CPU performs all types of
data processing operations. It stores data, intermediate results, and
instructions (program). It controls the operation of all parts of the
computer.
CPU itself has the following three components:
ALU (Arithmetic Logic Unit)
Memory Unit
Control Unit
Output Unit
The output unit consists of devices with the help of which we get the
information from the computer. This unit is a link between the computer
and the users. Output devices translate the computer's output into a form
understandable by the users.

WORLD WIDE WEB (WWW)
The World Wide Web is abbreviated
as WWW and is commonly known as
the web. The WWW was initiated by
CERN (European library for Nuclear
Research) in 1989.
WWW can be defined as the
collection of different websites

different information shared via local
servers(or computers).
