It is important for any computer system to consider the internal components, they need to be compatible in order to make a fully functional computer system. When you do not consider how the components interact with each other (either connecting together physically or communicate/share information). Processors The processor works like the brain of the computer, it carries out all of the instructions and calculations required to run your programs. In order to process instructions, they need to know which instructions they may need to run. For this reason, processors fall into two main categories RISC (Reduced Instruction Set Computing) and CISC (Complex Instruction Set Computing). RISC processors are used when computing tasks are simple and standardised, with only one layer of instructions (which are fixed-length). They can only run one instruction per cycle, so perform better with sequential programs. To make best use of a RISC processor, you need to know that the amount of RAM you have is often the bottleneck. CISC processors are used when there are a larger number of more complex instructions which need to be run (which vary in length). They can run more than one instruction per cycle, so can have increased performance with non-sequential programming. The CISC processors make more efficient use of RAM and relies on effective and reliable hardware rather than software. Random fact: Processor type (RISC vs CISC) is one of the only remaining non-standardised hardware components which are still being used today>
