Computer can be used as a calculating machine to produce results at a very high speed.
However calculation is not only use of computer.people use computer to solve different
problems quickly and easily. Computer are available in different shapes and sizes.A
common type of computer system is as follows.
System unit, Monitor,Keyboard,Mouse and Speaker etc.
Characteristics and Advantages of Computer
The imported characteristics of a computer are as follows.
Speed:-Computer processes data at a very high speed.It is much faster then human beings.
A computer can perform billions of calculations in second.For example, the process 769
and 877 can take one or two minutes if it is performed by human beings.However,a computer
can perform millions of such calculations within second.Computer speed is measured in mega
hertz(MHz)or giga hertz(GHz).
Reliability:-computer is very reliable.The electronic components in modern computer
rarely break or fail.
Storage:-Computer can store a large amount of data permanently.People can use this
data at any time.The user can store any type of data in computer.The storage capacity
of computer is increasing rapidly.A computer can store thousands of books easily.
Processing:-A computer can process the given instructions.It can perform different types
of processing like addition,subtraction,multiplication and division.It can also perform logical
functions like coma ring two numbers to decide which one is the bigger etc.
Accuracy:-Accuracy means that computer provides results without any errors.Computer
can process large amounts of data and produce results accurately.The result can be wrong
only if the data given to the computer is not correct.Suppose the average marks of a class
are required.There can be chance of mistake in the result if it is performed by human beings.
However,a computer can produce this result very accurately and quickly.
Recalling:-A computer can recall the storage data and information as and when required.
The data stored in 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.
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 jobs with equal
attention.
Versatile:-Computer is a versatile machine.It can perform different types of tasks.That is
way it is being used in every field of life.Computer is used in hospitals,banks,offices,and
at home.A user can ply games ,listen music, watch movies and use the Internet using a
computer.
Communication:-Most computer today have the capability of communicating with
other computers.We can connect two or more computers by a communication device
such as modem.These computers can share data,instructions,and information.The connected
computers are called network.We can communicate with other people in the world using
network like Internet.
Cost Reductions:-We can perform a difficult task in less time and less cost.For example,
we may have to hire many people to handle an office.The same work can be performed
by single person with the help of a computer.It reduces the cost
