Describe RAM and virtual memory, and explain why these are forms of temporary storage
What will be an ideal response?
Random Access Memory (RAM) holds the programs and data that a system is using while the system is powered on. When the system is shut down, the contents of RAM are emptied, thus considering RAM temporary or volatile storage. When there is not enough space in RAM to hold all the instructions and data in use, the less needed programs and data are transferred to an area on the hard drive where it is temporarily stored until it is needed. This is called virtual memory.
