Process: • Process is a program under execution. • A series of actions or steps that converts an input to an output by doing work.
Processing: Processing is the stage where the input data is manipulating in order to produce meaningful information. Process can include a number of stages. Sorting Searching Graphing Calculation
Processing Speed: Processing speed is the amount of time required to perform an intellectual task or the amount of work done that can be completed within a certain period of time.
States: Fetch Decode There are four distinct states that processing goes through. Execute Writeback
Stages: • Fetch : Fetch is the firststate ,in which the computer access its memory to retrieve instructions ,which are always a series of numbers represented in binary code. • Decode :Instructions are now broken up into meaningful parts or a series of bytes by the CPU’s control unit.
Execution :These instructions are then executed by CU. • When the instructions are complex mathematical calculations ,the CPU draws on its arithmetic logic unit to execute to them .In the final computer processing step , a write back of the data occur .It can be stored in the memory registers to the CPU itself for later use by the program.
