In this we will discuss characteristics of computer system.
Computers work very fast. It takes only few seconds for calculations for which humans take hours to complete. The weather forecasting that you see every day on TV is the result of compilation and analysis of huge amount of data on temperature, humidity, pressure, etc. of various places on computers. It takes few minutes for the computer to process this huge amount of data and give the result.
The degree of accuracy of computer is very high and every calculation is performed with the same accuracy. The errors in computer are mainly due to humans and inaccurate data.
A computer is free from tiredness, lack of concentration, fatigue, etc. It can work for hours without giving any error.
It means the capacity to perform completely different type of work. You may use your computer to prepare payroll slips. Next moment you may use it for creating some animation or for editing audio and video files.
Power of Remembering :
Computer has the power of storing any amount of information or data. Any information can be stored and recalled as long as you require it, for any number of years. It depends entirely upon you how much data you want to store in a computer and when to lose or retrieve these data.
No IQ :
Computer is a dumb machine and it cannot do any work without instruction from the user. It performs the instructions at tremendous speed and with accuracy but it is for the user to decide that what the computer will do and in what sequence. So a computer cannot take its own decision as you can.
No Feeling :
It does not have feelings or emotion, taste, knowledge and experience. It does not distinguish between users.
The Computer has an in-built memory where it can store a large amount of data. You can also store data in secondary storage devices such as CD‟s, which can be kept outside your computer and can be carried to other computers.
