Memory Management Strategies Quiz

What is the primary purpose of memory management in an operating system?

• To increase CPU speed

• To manage the allocation of memory resources

• To improve disk storage

• To enhance user interface

What does the term 'swapping' refer to in memory management?

• Releasing memory from terminated processes

• Allocating memory to new processes

• Moving processes between main memory and disk

• Transferring data between CPU and cache

Which of the following is a method of memory allocation?

• Dynamic memory allocation

• Static memory allocation

• All of the above

• Contiguous memory allocation

What is a base and limit register used for?

• To define the physical address space

• To check memory access for user processes

• To allocate disk space

• To manage CPU scheduling

What is the main advantage of paging?

• Reduces the need for disk storage

• Increases memory speed

• Eliminates external fragmentation

• Simplifies memory allocation

What is internal fragmentation?

• Memory that is inaccessible

• Memory allocated to a process that is too small

• Unused memory within a partition

• Memory that is not contiguous

Which memory management technique divides memory into fixed-size blocks?

What does the Memory Management Unit (MMU) do?

• Maps virtual addresses to physical addresses

• Allocates disk space

• Handles input/output operations

• Manages CPU scheduling

What is the purpose of a page table?

• To map logical addresses to physical addresses

• To store process data
