Today, much of the world’s infrastructure runs on computers and it has profoundly changed our lives, mostly for the better. Let us discuss some of the characteristics of computers.

The human race developed computers so that they could perform intricate operations, such as calculation and data processing, or simply for entertainment. Today, much of the world’s infrastructure runs on computers and it has profoundly changed our lives, mostly for the better. Let us discuss some of the characteristics of computers.

AUTOMATIC:

A machine is said to be automatic, it works by itself without human intervention. they cannot go out and find their own problems and solutions. they have to be instructed.

VISION OF AUTOMATION:

A hundred years ago, the concept of the future lacked a major ingredient the computer! artist unknown, circa 1895.

SPEED:

The computers process data at an extremely fast rate, at millions of instructions per second. in few seconds, a computer can perform such a huge task that normal human beings may take days (or) even years to complete. the speed of the computer is calculated in MHz that is one million operations per second. a powerful computer is capable of performing several billions of complicated arithmetic operations per second.

ACCURACY:

Besides the efficiency, the computers are also very accurate. the level of accuracy depends on the instructions and the type of machines being used. since the computer is capable of doing only what it is instructed to do, faulty instructions for data processing may lead to faulty results. this is known as GIGO(Garbage In Garbage Out).

DILIGENCE:

A computer, being a machine, does not suffer from the human traits of tiredness and lack of concentration. if four million calculations have to be performed, then the computer will perform the last four millionth calculation with the same accuracy and speed as the first calculation.

RELIABILITY:

Generally, reliability is the measurement of the performance of a computer, which is measured against some predetermined standard for operation without any failure. the major reason behind the reliability of the computers is that, of hardware level, it does not require any human intervention between its processing operations. moreover, computers have built-in diagnostics capabilities, which help in continuous monitoring of the system.

STORAGE CAPACITY:

Computers can store large amounts of data and recall the required information almost instantaneously. the main memory of the computer is relatively small and it can hold only a certain amount of information, therefore, the data is stored on secondary storage devices such as magnetic tape(or) disks. small sections of the data are stored on secondary devices such as magnetic tape (or) a small section of the data can be accessed very quickly and bought into the storage devices, as and when required, for processing.

VERSATILITY:

Computers are quite versatile in nature. it can perform multiple tasks simultaneously with equal ease. for example, at one moment it can be used to draft a letter, another can be used to play music and in between, one can print a document as well. all this work is possible by changing the program(computer instructions).

RESOURCE SHARING:

In the initial stages of development, computers used to be isolated machines. with the tremendous growth in computer technologies, computers today have the capability to connect with each other. apart from device sharing, data and information can also be shared among groups of computers, thus creating a large information and knowledge base.

Although processing has become less tedious with the development of computers, it is still a time-consuming and expensive job. sometimes, a program works properly for some period and then suddenly produces an error. this happens because of a rare combination of events or due to an error in the instruction provided by the user.

COMPUTER LIMITATIONS:

  • 100% data security is impossible but we can try to maximize it.
  • Restless computer usage may spoil our health(eye, nerve system, etc.)
  • A computer can only perform what it is programmed to do.
  • The computer needs well-defined instructions to perform any operations.
  • Hence, computers are unable to give any conclusion without going through intermediate steps.
  • A computer’s use is limited in areas where quality considerations are important. for instance, it can make plans based on situations and information but it cannot foresee whether they will succeed (or) not.
