Find out about CPU's, RAM's and HDD's
RAM stands for Random Access Memory. This is the part that stores data that is currently in use. This means the more memory you have, the more data and programs you can have open at one time. On a modern computer you will probably have around 1-8 gigabytes of RAM. Memory that loses its data when the power is removed is called volatile memory.
