1. Pre-paging occurs when the system finds itself spending so much time swapping pages into and out from memory that little time is left for useful work. 2. Memory mapping is a technique for managing memory. 3. Traditionally, the key measure of multiprogramming effectiveness is response time. 4. The system operator manages the processor’s time by determining which application program is executed next. 5. On many systems, a control block is created to hold a partition’s key control flags, constants, and variables.
