How Computers Work!
CPUs - RAM - HDDs - What is it all about?
RAM stands for Random Access Memory. This stores data that is currently in use. This data is volatile, meaning it is removed when the power is removed. It is measured in Gigabytes and most computers have between 1-8Gb of memory, but some have up to 16Gb. The more memory you have the more programs you can have open at once.
