An ICT system is a set-up consisting of hardware, software, data and the people who use them. It commonly includes communications technology, such as the Internet.
The three main types of ICT systems
Information systems: This type of ICT system is focused on managing data and information.
For examples: these are a sports club membership system or a supermarket stock system.
Control systems: These ICT systems are mostly part to control machines. They use input, process and output, 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
