Paper 1
Revise: Purpose of RAMRAM is also volatile, meaning that its contents are lost when power is removed. This makes RAM suitable as temporary working memory, but not as the only place to keep a document permanently. If the computer loses power before you save your changes, the saved copy may still exist, but changes held only in RAM are lost.
For a question about RAM’s purpose, state that it stores data and instructions currently in use so the CPU can access them. Saying only that RAM is volatile does not explain its purpose.
