OS LO2 2 Memory Management

What is the main aim of memory management?

• To improve network connectivity

• To increase CPU speed

• To reduce disk space

• To achieve efficient utilization of memory

What is the purpose of swapping in memory management?

• To temporarily move a process from main memory to secondary memory

• To increase internal fragmentation

• To reduce memory allocation

• To improve CPU performance

Which memory allocation technique allocates the smallest hole that is big enough to process requirements?

• Worst fit

• Random fit

• Best fit

• First fit

What is the major issue with worst fit memory allocation technique?

• Low disk space

• Inefficient memory utilization

• High CPU usage

• Increased fragmentation

What is the term used to describe memory blocks that cannot be allocated to processes due to their small size?

• Swapping

• Compaction

• Fragmentation

• Segmentation

How is internal fragmentation caused in memory management?

• When memory is fully utilized

• When processes are swapped

• When memory blocks are contiguous

• When a process is allocated a memory block of size more than the process size

What technique is used to overcome external fragmentation in memory management?

• Segmentation

• Swapping

• Compaction

• Paging

What is the purpose of segmentation in memory management?

• To divide memory into different segments for storing specific data or code

• To increase memory allocation speed

• To reduce CPU usage

• To improve disk performance

What is the purpose of paging in memory management?

• To reduce memory access speed

• To increase internal fragmentation

• To break memory into fixed-size blocks known as pages

• To improve network connectivity
