What is the main disadvantage of fixed partitioning?

• External Fragmentation

• Dynamic Partitioning

• No Internal Fragmentation

• Complex Memory Allocation

Which memory management technique tries to overcome the problems caused by fixed partitioning?

• Dynamic Partitioning

• Compaction

• Paging

• Segmentation

What is the main purpose of the Memory Management Unit (MMU)?

• To handle fragmentation

• To allocate memory to processes

• To manage the page table

• To convert logical addresses into physical addresses

What is the primary advantage of using dynamic partitioning over fixed partitioning?

• Simpler Memory Management

• Faster Memory Access

• No Internal Fragmentation

• Lower Memory Overhead

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

• High page fault rate leading to excessive paging

• Inefficient memory allocation

• Fragmentation of memory

• Low CPU utilization

In the context of paging, what is a page fault?

• When a page is swapped out

• When memory is full

• When a page is successfully loaded

• When a requested page is not found in memory

Which page replacement algorithm replaces the page that will not be used for the longest time in the future?

• Least Recently Used (LRU)

• First-In-First-Out (FIFO)

• Optimal Page Replacement

• Best Fit

What is the main disadvantage of using a bitmap for dynamic partitioning?

• It requires additional memory for the bitmap

• It is slower than linked lists

• It cannot track free partitions

• It leads to internal fragmentation
