Characteristics of a Computer System

1.     Accuracy:   computers operate at a very high degree of accuracy. It does not become exhausted easily to the extent of making mistakes.

2.     Speed:     computer is generally known for its speed. The speed of computer is measure in millions of instruction per seconds and it increases progressively as the computer develops.

3.     Reliability;      the computer responds to the instruction keyed into it without any alteration, as a result of this, it gives no room for doubt over out output. Therefore, the operator relies on it for effectiveness. Example include a program  computer device to ring alarm to alert workers of any emergency, a programmed entry and exit door used in big companies and supermarkets, offices, etc.

4     Versatility;     it fits into different fields of human endeavor ranging from business, education, technology, engineering, law, commerce, agriculture, medicine, sports.etc  it can perform different types of tasks provided such tasks can be stated in logical way for the computer to execute.

5.   Large Storage Capacity:    vast quantities of data stored in paper files would become extremely bulky and require substantial storage space.  Furthermore, the job of manually extracting data from such files would become increasingly tedious and time consuming as the size of the files increases.  But with the computer, data can be stored electronically in considerable less space, and retrieve in a fraction of the time needed by the manual method. The ability of the computer to store, retrieve and process data, all without human intervention gives it power and appeal over that of human.

So, while human can perform the same function as the computer, the difference and major benefits is that the computer can reliably execute millions of instructions in a second and stored the result in an almost unlimited memory.

6.   Programmability: The computer can be programmed to do all forms of activities of man. Programming in computer means the act of writing computers programs and this involves the use of special set of characters, signs, symbols, to supply instruction to the computer for execution towards achieving specific tasks (motives). This opportunity gave room for the computer to be a versatile system.
