Processes 01

This KS3 ICT quiz asks questions regarding processes. A process is where input is transformed into output. Processing is carried out in the central processing unit (CPU). Some of the processing is carried out by the operating system but the rest is performed by computer programs (note the different spelling to the programmes you watch on a TV). Applications software is a general term for computer programs that enable computer users to carry out specific tasks like word processing or image manipulation.

Computer programs are made up from a number of procedures that tell a computer's CPU what to do with the input it receives. These are linked together and each one is designed to perform a specific job, e.g. sharpen an image, underline text, perform a methematical calculation etc. Companies who sell applications software re-evaluate their products every so often and write new procedures that can make them do new things or old things just a little bit better.
