3. Speed
3
Computer process data at very high speed.
It is much faster then human beings.
A computer can perform billions of
calculations in a second.
Computer speed is measured in Mega Hertz
(MHz) or Giga Hertz (GHz)
4. 4
Reliability
Computer is very Reliable.
The electronic components in modern
computer rarely break or fail.
A computer is reliable as it gives consistent
result for similar set of data i.e., if we give
same set of input any number of times, we
will get the same result.
5. 5
Storage
Computer can store large amount of data
permanently.
The user can store any type of data in the
computer.
The storage capacity of computer is increasing
rapidly.
The storage capacity of computer is commonly
measured in Mega-Byte (MB), Giga-Byte (GB),
Tera-Byte (TB) and Peta-Byte (PB).
6. 6
Processing
A computer can process given instructions.
It can perform different types of processing
like addition, subtraction, multiplication and
division.
It can also perform logical functions like
comparing two numbers to decide which one
is the bigger etc.
7. 7
Accuracy
Accuracy means that computer provides results without any
errors.
Computer can process large amounts of data and produce
results accurately.
The Accuracy of the computer is constantly high and it can
perform hundred of operation with the carry-out calculation
and analysis accurately and speedily
A computer never gives us wrong results under any
circumstances. You can absolutely trust the output of the
computer.
8. 8
Recalling
A computer can recall the stored data and information as
and when required.
The data stored in the computer can be used at a later time.
The computer can recall the required data in a few seconds.
Control Sequence
A computer works strictly according to the given instructions.
It follows the same sequence of execution that is given in a
program.
9. 9
Consistency
Computer works in a consistent way.
It does not lose concentration due to heavy work.
It does not become tired or bored.
Computer performs all the jobs with equal attention.
Versatile
Computer is a versatile machine. It can perform different types
of tasks. That is why it is being used in every field of life.
Computer is used in hospitals, banks, offices and at home.
A user can play games, listen to music, watch movies and use the
internet using computer.
10. 10
Communication
Most computers have the capability of
communicating with other computers.
The computers can be used to form a network
to share data and information with other
people.
The internet is an example of network that is
used by millions of people around the world to
communicate effectively and easily.
