What are Charachteristics of Computer

Following are the important characteristics of a computer:

1. Speed

Computers work at a very high speed. They are much faster than humans.

A computer can perform billions of calculations in a second. Computer speed is measured in Mega Hertz (MHz).

2. Storage

A computer can store large amounts of data permanently.

3. Processing

A computer can process the given instructions for processing of data. It can perform different types of processing like addition, subtraction, multiplication and division.

4. Accuracy

Accuracy means the capability to provide results without any errors. Computer can process large amounts of data and produce 100% accurate results.

5. Recalling

A computer can recall the stored data and information at any time, as and when required.

6. Cost Reduction

Computer can reduce cost. We can do a work in less time and cost by computer. A single person, with computer, can do work of many people in an office.

8. Versatile

A computer can perform different types of tasks. We can use a computer in educational institute, in hospital, bank or at home. computers are being used in banks industry, medical, science and engineering fields.

9. No Feelings

Computer has no feelings. It cannot be affected by sorrows and happiness.

10. No Intelligence

Computer itself is not intelligent. It only follows the given instructions. If a computer is given a program for addition it cannot perform subtraction by itself.

Example 3: <Table align="left" border="2"> => A left aligned Table with a border of width 2. ...

Explain The Concept of A Computer System

A system is a set of inter related components that work together to fulfill a purpose. For example a Road Transportation System will consist of the parts - roads, vehicles- trucks, buses, vans, cars etc, passengers, the staff for ticketing and maintenance of vehicles and roads etc. And the transportation system will fulfill the purpose of carrying of passengers and luggage from place to place. Similarly, a computer system consists of many components that work together to fulfill the purpose of data processing. A Computer system consists of the following four parts: 1. Hardware 2. Software 3. Data 4. User 1. Hardware The mechanical devices that makeup the computer are called HARDWARE , for example, Keyboard, hard disk, monitor, processor and mother board etc. Hardware are physical devices . They can be touched. Hardware device are interconnected and perform input, processing and output o...
