Memory Management Techniques Quiz

Which of the following is not a memory management technique?

• Paging

• Segmentation

• Fragmentation

• Swapping

In paging, the address generated by the CPU is divided into:

• Page number and page offset

• Segment number and offset

• Frame number and frame offset

• Logical and physical address

Which of the following causes external fragmentation?

• Paging

• Segmentation

• Contiguous memory allocation

• Virtual memory

Internal fragmentation occurs when:

• Memory is divided into variable-sized partitions

• Memory is divided into fixed-sized partitions

• Pages are larger than frames

• Swapping is used

Virtual memory is:

• Memory on the hard disk

• A large amount of main memory

• An illusion of a large memory using disk space

• Cache memory

Thrashing occurs when:

• All processes are waiting for I/O

• The system spends most of its time swapping pages

• The CPU is overloaded

• Page size is too large

The main function of the Memory Management Unit (MMU) is to:

• Handle page faults

• Convert logical addresses to physical addresses

• Manage disk storage

• Allocate CPU registers

Which of the following is a disadvantage of paging?

• External fragmentation

• Internal fragmentation

• No memory protection

• Complicated memory allocation

In segmentation, a logical address consists of:

• Page number and offset

• Segment number and offset

• Frame number and page number

• Page table and base register

Which memory allocation method may lead to the best memory utilization?

• First-fit

• Best-fit

• Worst-fit

• Random-fit
