FEATURES (CHARACTERISTICS)OF COMPUTER
the growing importance of computer applications is due to its powerful features.
the main features of a computer are as follows:
1 speed. modern digital computer works at very fast speed. the speed or execution of operations by modern computers is several million operation per second. its speed has facilitated industry to make desired data available within seconds.
2 Storage. a large volume of information can be stored in temporary memory computer can store almost limitless volume of information in secondary media such as floppy, disk,magnetic disk and tapes etc. storage of voluminous data in secondary devices saves space and time both in storing and extraction of information.
3 Accuracy. the computer produces 100% accurate results but it depends upon teh computer operator. the term 'GIGO' is popularly used regarding computer accuracy. GIGO mean "garbage in, garbage out". its means if the operator given wrong instructions to the computer or feeds worng data into, it the result is bound to be inaccurate. Errors in computer results are, without exception, due to human rather than due to technological weakness of the computer.
4 Automation. a computer has now become an important office automation tool. to perform many operation, the only human effort required is to press some keys the rest is automatically done by the system based upon the programmer instructions. the means that the operator is not required to give instructions at each stage of operation. such an automate execution of operations continues till an instruction is given to stop.
5 Versatility. a computer has wide applications. it can be used to solve problems relating to difference fields. these days there is hardly any area where computers are not used. computers are used in business and industry, science, research, offices etc.
6 Diligence. unlike human beings whose efficiency and effectiveness decreases with passage of time. computer maintains its efficiency and accuracy consistently. a computer never tires doing the same job again even for a million of time without lack of concentration.
7 Scientific Approach. in computers, the entire portage to problem solving is scientific and logical. it is absolutely free from emotions and the results are determined from the information fed into the computer.
8 Logical decisions. logical decisions are possible with the help of computer because computer can process the information for various possible alternatives (simulations). hence, only the logical decision is the likely outcome.
