1.2 Virtual Memory (8. J277 C&D)

What happens when a modern multi-tasking operating system runs out of physical RAM?

• It shuts down automatically to prevent data loss

• It outputs a 'memory full' message and refuses to open any more programs or data

• It deletes less important data to make space

• It uses virtual memory as a solution
