Types of computer systems
- Multi-functional devices
- Multi-functional devices are those that perform multiple functions, such as printers that include a built in scanner. The scanner is often on top of the device so that it can also be used as a photocopier.

- Servers
- Servers are computers that run operating systems such as Microsoft,Windows server
- They are used to control the network and users logged into the system on workstations (also known as client computers),
