Information Processing Cycle

A series of steps used to convert data into useful information is known as Information Procession Cycle.
The steps in this cycle are performed in a specific sequence.

 Different steps in Information Processing Cycle are as follows:-



Input:
The first step of information processing cycle is input. The computer accept data in this step. Data consist of raw facts and figures. Data is entered into computer for processing. It is entered using input devices like a keyboard or mouse.


Processing:
The second step of Information Processing Cycle is Processing. It converts data into information. Information is an Organized and Processed form of data. The central processing unit process data into useful information. Random Access Memory (RAM) temporarily stores program and data required by the CPU.


Output:
The third step of Information Processing Cycle is Output. The results are provided to user in this step. It is performed using different output devices such as monitors and Printers.




Storage:
The fourth step of Information Processing Cycle is Storage. It stores data ,information and programs used by the computer systems. It is performed using different storage devices like hard disk drives,CD,DVD and USB flash memory etc.
