main memory
CPU's direct workspace
Main memory is the primary working storage in a computer, where the processor keeps data and instructions it needs immediate access to.
Unlike storage drives, main memory—typically RAM—is fast but volatile, meaning its contents disappear when power is lost.
Programs must be loaded into main memory to run, and insufficient main memory forces a computer to use slower disk-based alternatives.
The application crashed because the system ran out of main memory.
