Characteristics of Computer

Characteristics of Computer: The computer system has a logical program to solve complex problems. The features of computer make it fast and powerful. The computer with powerful features can perform about 3 to 4 million simple instructions per second. The universal serial (USB) bus is used to connect the external device to the computer. The computer is a combination of various kinds of separate electronic devices.

Features of Computer

  • It response the set of instructions in a well-defined manner, and it can execute the pre-recorded list of given instruction.
  • The personal computer has a small and inexpensive design for individual use and based on microprocessor technology.
Characteristics of computer

There are different Features of Computer which are given the following:

1. Speed

The computer can work very fast. It takes some seconds to calculate the complex numerical problem. The normal human being is never able to compete with the speed of the computer system. The computer can perform billions of instructions per second. We can measure the speed of the computer in terms of microsecond or nanosecond so that we cannot imagine the processing speed of the computer. The speed rate of the computer depends on its processor. We can measure the speed of our computer processor in hertz and Gigahertz.

2. Accuracy

The accuracy level of the computer is very high. The errors come in the computer due to inaccurate human input. The computer is never creating a mistake; it shows the error if the user gave the wrong data to the computer. The computers do not get tired or bored like us; they can do the same task repetitively with the same accuracy.

3. Storage

The computer has its internal memory, which is known as primary memory. We can store the vast amount of data in that memory. We can also save the data in secondary storage devices such as pen drive, floppy disk, compact disk, etc.

4. Versatility

Versatility means the performance of the computer. When we are doing a different task at the same time, the computer can do these tasks correctly. We can say that human is confused by doing many tasks at the same time, but we can do these things with the help of a computer.

The computer has high Versatility, and for example, when we prepare our payroll slips at the same, we can make the electric bills. It is not only used to calculate numeric values, but it can also be used in various fields like medical, scientific experiments, multimedia, etc. 

5. Reliability

There are various types of components that exist in the computer system, such as motherboard, keyboard, mouse, etc. These components are very reliable and easy to use. The computer can execute billions of tasks in second. 

The reliability is an attribute of the computer system. If a program is executed many numbers of times with the same set of data, every time the result would be the same: that is possible due to its reliability feature.

6. Automation

Automation is the feature of the computer system. It performs the task which is previously instructed by humans. For example, if we want to print some pages through the printer so, we have to give instruction once to the computer to print the pages. We do not need to instruct, again and again, the work will continue automatically.

7. Logical

The computer is not able to think and take the decision itself. It can take logical decision with the help of programs which are written in different languages. The logical feature of the computer is also used in the scientific and industrial calculation, where the extended range of data is used for information.

8. No IQ

The computer has no IQ level, like humans. It does not work without human instruction and does not have its intelligence power. The computer is not able to make decisions.

9. No feeling

The computer does not have emotions, knowledge, experience, feeling, it works according to human desire and follow the instruction of humans.

10. Diligence

The computer can work continuously without any break and creating error, and it never gets irritated with the work. The computer can reply again and again of similar things; still, it can produce an accurate result.
