What is Computer, Basic about Computer
In this Tutorial you will learn some basic about computer system, such as What is Computer, Functions of Computer and Characteristic of Computer. Now you read one by one all topic given below.
What is Computer?
- A Computer can be defined as an electronic device that is design to accept data perform the required mathematical and logical operation at heigh speed and output the best and fast result.
- A computer is an electronic device that performs calculations and operations based on instructions provided by a software or hardware program.
We have seen computer in our houses, schools, colleges, offices, etc. In facts in today, we find computer in most aspect of our daily life.
Computer have become so prevent in the market that or interactive device such as cellular device (GPS) Global Processing Device.
Functions of Computer
Program; – A computer is an electronic device that perform a function based on a given set of instructions are knowns as program.
Characteristics of Computers
-
Speed: – Computer can perform a million of operations per second. The speed of computations is very height.
The speed of computer is usually given in nanosecond and picosecond.
1 Nanosecond = 1 x 10-9 Sec
1 Picosecond = 1 x 10-12 Sec
-
Accuracy: – A computer is a very fast, reliable and robust electronic devices is always provided accurate results. As computer work on inbuilt software programs, there is no scope form human errors and highly accurate.
- Automaton: – Computer are automation device. That can perform a task without any user intervention.
- Diligence: – Computer are highly reliable. They can perform complex and long calculations with the same speed and accuracy. It can continually work an hour without creating an error.
-
Versality: – Versality is the quality of being flexible. Today computer is use in our daily life in different – different filled. Compute is versatile in Nature. they can perform various operations at the same time.
-
Storage: – Computer can store a large amount of data or instructions in its memory which can be retrieved at any point of time.
- No IQ: – Computer do not have any decision-making ability. Dose there IQ level is Zero.
-
Memory: – Computer have internal memory, primary memory, external memory and secondary memory. The internal memory of compute is very expensive and limited storage inside. But the secondary storage is bigger capacity.
The computers store in large amount of data and program in the secondary storage. The stored data and program can be reserved and used whatever required, Secondary memory include HDD, Pen drive, Floppy Disk etc.
