IOPS cycle is an organized procedure through which all processing within a computer takes place. And it takes place through four operations. 1. Input 2. Processing 3. Output 4. Storage
1. Input Operation: In the input operation, data is entered or otherwise captured electronically and is converted to a form (machine language) that can be processed by the computer. 2. Processing Operation: In the processing operation, the data is manipulated to process or transform it into information, which is usable for people. And it takes place through four steps, which is called the machine cycle. 3. Output Operation: In this operation, the information, which has bben processed from data, is produced in a form usable by people. Examples of output are printered text, sound, and charts and graphs displayed on a computer screen. 4. Storage Operation: In the Storage Operation, data, information, and programs are stored in computer process able form. Diskettes are examples of materials used for storage.
All the operation of IPOS cycle in done on the machine cycle. Machine cycle consist of four parts. 1. Fetching 2. Decoding 3. Executing 4. Store Working Storage Area

1. Fetching: In this process the data is fetched from the program storage Area send to Control Unit. 2. Decode: In this process the fetched data in CU is decoded to machine language, all the information are Scand the operands and operations are set and sent to ALU. 3. Execute: During the execution cycle, or E cycle, arithmetic/logic unit executes the instruction (performs the operation on the data and stores the processed results in the main memory or register. If it is final result, it is stored in output storage area but if more jobs were to be done on it, it is sent to
