Using an example, describe the importance of reliability in computer systems
b) You need computer systems to be reliable, as you are reliant on them to perform tasks. For example, if a life support machine fails, the patient will die.
A number of things could happen if technology was always unreliable. You might stop using the equipment for good. You might get very stressed out and frustrated over time. You might decide never to buy a product from that manufacturer again. Manufacturers might go out of business if enough people felt the same way. You might change your habits.

Give three reasons why new ICT systems may fail to deliver what they were intended to do
c) – Human error in the coding - The system may not have the hardware power to perform the task - Underestimated traffic on the server
Describe the following terms:

2) - A computer system that performs a specific task.
An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints.
