Characteristics of computer

The important characteristics of a computer are as follows:
    1. Speed
    2. Reliability
    3. Accuracy
    4. Diligence
    5. Versatility
    6. Power of Remembering
    7. No IQ
    8. No Feeling
    9. Storage
    10. Consistency
    11. Communication
    12. Recalling
    13. Control Sequence
    14. Cost Reduction

1. Speed

Computer processes data at a very high speed. It is much faster than human beings. A computer can perform billions of calculations in a second. Computer speed is measured in Mega Hertz (MHz) or Giga Hertz (GHz). For example, the process of multiplying 750 and 927can take one or two minutes if it is performed by human beings. however, a computer can perform millions of such calculations within a second.

Computers run much faster and faster than humans. Computers can process millions (1,000,000) of instructions per second. The time it takes for a computer to start up is micro power and nanoseconds.

Thus, we define the speed of a computer as micro-cower (10-6 parts per second) or nanoseconds (10 energies – 9 parts per second). From this, you can imagine how fast your computer is running.

2. Reliability

Computer is very reliable. The electronic components in modern computer rarely break or fail.

3. Accuracy

Accuracy means that the 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 a chance of mistake in the result if it is performed by human beings. However, a computer can produce this result very accurately and quickly.

The accuracy of the computer is very high and all calculations are performed with the same accuracy. Accuracy level 7.Computers perform calculations with 100% accuracy. Errors may occur due to inconsistencies or inaccuracies in the data. Computer design decisions. Computer errors are caused by incorrect human data.

4. Diligence

A computer can stably and accurately perform millions of tasks or calculations. When millions of calculations are performed, the computer performs all calculations with the same accuracy.

Computers are not tired, lack of concentration, tired, etc. It can work for several hours without errors. Don’t get tired or focus. His memory is also better than that of man. Due to this ability, there is a constant workload.

5. Versatility

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 hospital bank, office and at home. A user can play games, listen to music, watch movies and use the internet using a computer.

This means that the ability to work is completely different. You can use a computer to create a payroll. Versatility refers to the ability of a computer to perform a variety of tasks with equal accuracy and efficiency. Next time, you can use the app to manage inventory or bill electricity.

6. Power of Remembering

The computer has the ability to store any information or data. It all depends on the amount of data stored on your computer and how long you lose or recover the data. Any information can be stored and retrieved for as many years as you need.

7. No IQ

A computer is a stupid machine and cannot do anything without user instructions. Therefore, the computer cannot make as many decisions as it can. Follow the instructions quickly and accurately. What and in what order, is up to you.

The computer is reliable because it gives consistent results for the same amount of data, which means that if we give the same input several times, we get the same result.

8. No Feeling

They have no feeling, no emotion, no taste, no knowledge, no experience. So don’t get tired even after working hours. Do not pray among consumers. Computers perform all tasks automatically, which means they perform tasks without manual intervention.

9. 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 the computer. The storage capacity of computer is increasing rapidly. A computer can store thousand of books easily.

Computers have an internal memory that can hold a lot of data. You can also save data to a secondary storage device, such as a floppy disk, that can be stored outside of a computer and transferred to another computer. Your computer has internal memory called main memory for storing data. A secondary storage device is a removable device, such as a CD, pen drive, etc., that is also used to store data.

10. 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.

11. Communication

Most computers today have the capability of communicating with other computers. The computers can be connected using a communication device such as modem. These computers can share data, instructions and information. A set of computers connected together is known as network. It ca be used to communicate with other people in the world. The Internet is an example of a network.

12. 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.

13. Control Sequence

A computer works strictly according to the given instructions. It follows the same sequence of execution that is given in a program.

14. Cost Reductions

A computer can help in performing a different task in less time and cost. For example, many people may be required in an office to perform different tasks manually. The same work can be performed by a single person with the help of computer. it reduces the cost.
