- A combination of hardware and software components that allow input, processing and output of data. | Computer System
- The physical components that make up a computer system. | Hardware
- The programs that run on a computer system. | Software
- Hardware devices that take real-world analogue data and convert it into a digital form that can be stored on a computer. For example: keyboard, mouse, microphone, webcam, scanner, sensors. | Input Devices
- Hardware devices that use digital data from a computer to produce a form that is understandable to a person. For example: monitors, printers, speakers, projectors, actuators (motors). | Output Device
- How much you can depend on the computer system being available when you need it. Usually measured in terms of availability. | Reliability
- The proportion of time that a system is operational, usually expressed as a percentage over a certain period of time. For example, 95% measured over 1 year. | Availability
- A measure of availability often quoted by hardware manufacturers. For example 2.56 years between failures means that, on average, the hardware can be expected to last 2.56 years before it goes wrong. | Mean Time Between Failure (MTBF)
- Spare hardware components are built into a system so, in the event of a component failing, the system can swap over to the spare one. | Redundancy
- Where a company has plans to replace a system quickly if there is a catastrophe (fire, flood, bomb etc). Designed to minimise the time the system is down. | Disaster Recovery
