Types of ICT system

The three main types of ICT system to be considered for GCSE are:

Information systems

This type of ICT system is focused on managing datadata: information without context, eg a list of students with numbers beside their names is data, when it's made clear that those numbers represent their placing in a 100 metre race, the data becomes information and informationinformation: data with context or meaning. Examples of these are a sports club membership system or a supermarket stock system.

Control systems

These ICT systems mainly control machines. They use inputinput: the term denoting either an entrance or changes which are inserted into a system and which activate/modify a process, process and outputoutput: the term denoting either an exit or changes which exit a system and which activate/modify a process, but the output may be moving a robot arm to weld a car chassis rather than information.

Communications systems

The output of these ICT systems is the successful transport of data from one place to another.
