Processing: Introduction
Processing is the act of manipulating data in some way, whether it be changing it or updating it. Consisting of millions of electrical componenets on a small cicruit, The CPU accepts all data from input devices, changes it according to its given instructions and sends the product to the set output device during the processing stage.
The fetch execute cycle describes the steps that the CPU goes through before a piece of data is manipulated.
1. Data is 'fetched' from memory
2. The Control unit of the CPU comprehends what has to be done to the information
3. The Arithmetic Logic unit of the CPU performs the actions
4. The resultant is stored in memory.
Before computers (Non-computer tools): Documentation was used to outline the steps of how a piece of data to be processed manually. It could be simple or detailed and it gave instructions to the person manipulating the data. BERL
