CPU'S carry out software instructions.

RAM - memory in computer system that is used for running software. Allows instructions to be loaded into the processor quickly. Holds all software instructions to be carried out, so more RAM will allow more programs to run at the same time. Instructions are loaded to RAM from storage (hard disk) therefore faster storage = faster loading of instructions.

VIRTUAL MEMORY - storage used by the processor once the space in RAM has run out.
