• Hard Drive

• Registers

Which memory allocation strategy assigns consecutive memory blocks to a process?

• Paging

• Segmentation

• Contiguous Memory Allocation

• Virtual Memory

What problem does fixed partitioning in memory allocation cause?

• Internal Fragmentation

In paging, what keeps track of pages in physical memory?

• Page Table

• Segment Table

• Cache

• Stack

Which of the following best describes virtual memory?

• Memory that is located on the CPU

• A technique that extends RAM using secondary storage

• Memory allocated to the operating system only

• Memory that cannot be swapped

Which page replacement algorithm removes the least recently used page?

• FIFO

• LRU

• Optimal Algorithm
