Week 3

What is the main advantage of the paged memory allocation method?

• Supports virtual memory easily

• Reduces memory pressure on system startup

• Better security

• Improves memory utilization

In demand paging, where are unaccessed pages stored until needed?

• Secondary storage (e.g., disk)

• Cache memory

• RAM

• Registers

What is the main advantage of the segmented memory allocation method?

• Reduces memory pressure on system startup

• Supports virtual memory easily

• Improves memory utilization

• Flexible memory management for different program sections

What is the main disadvantage of the segmented memory allocation method?

• Complex memory management

• Inefficient external fragmentation management

• Overhead of page faults when accessing unallocated pages

• Internal fragmentation within segments

What is the main benefit of the segmented/demand paged memory allocation method?

• Flexible memory management for different program sections

• Supports virtual memory easily

• Efficient memory usage

• Reduces memory pressure on system startup
