Memory is measured in kilobytes, megabytes and gigabytes. The amount of memory available to your computer depends on the size of your hard disk and the type of operating system you are using.
When you turn on your computer, it runs from its hard disk; however, many programs like word processors and spreadsheets require more memory than this. To solve this problem, many computers have a small amount of memory known as “RAM,” which stands for random access memory.
RAM is very fast because it is directly connected to the microprocessor (or CPU) in your computer. When you run a program that requires more memory, the computer copies part of it from RAM into the hard disk so that there is more space available in RAM for other programs. This process is known as virtual memory or swapping out because parts of programs are swapped out to make room for other programs that need more space in RAM.
