Chapter 1.1 Fundamentals of Computer systems

What is a computer system? A computer system is one that is able to take a set of inputs, process them and create a set of outputs. This is done by a combination of hardware and software. The computer system has one or more inputs to provide data. This data is then processed in some way. The outcome of the processing is sent to an output or it may be stored until some event happens to cause it to be output. For processing to take place, there needs to be a set of instructions of what needs to be done. This set of instructions is called a program. This system is called a stored-program computer.

1.2 CPU What is a CPU? What does it do?

The Fetch-Execute Cycle The CPU works on something called the fetch-execute cycle. It needs to fetch the data or instructions from the memory locations (fetch) It needs to work out what these data or instruction mean (decode) It then performs that task (execute) The whole process is repeated again. Fetch Decode Execute
