Describe what processing is. |
Processing is the central part of the computer system. It is where the input data is manipulated to produce correct and meaningful information. Its does stages, such as sorting, searching, calculations and graphting. E.g. A barcode is scanned, the process starts to search for the price of the item from the shops database to use to calculate the customers bill. |
