Memory management's main role is to ensure that each process gets adequate memory while optimizing the use of available memory resources to improve overall system performance.
Virtualization involves creating virtual versions of physical components and is not a direct technique for managing memory but rather related to overall system resources.
Paging divides memory into fixed-sized pages, allowing non-contiguous allocation and avoiding fragmentation issues, thereby enhancing efficiency in memory management.
Swapping refers to moving inactive processes to disk storage to free up main memory for active tasks, typically used when memory is insufficient.
The MMU handles the translation of virtual memory addresses, used by applications, into physical memory addresses, thereby facilitating efficient memory use and protection.
Segmentation deals with variable-sized memory blocks based on logical divisions within a program, unlike paging which uses fixed-size pages.
A page fault occurs when a program seeks to access data that is not currently held in the system's memory, leading to a fetch from secondary storage.
Virtual memory creates an abstraction of a large contiguous address space, appearing larger than the physical RAM, enhancing system flexibility and resource utilization.
Thrashing is caused by continuous swapping between the main memory and disk, due to insufficient memory or poor system configuration, degrading performance.
Free memory spaces are effectively managed using a linked list, offering dynamic insertion and removal of blocks, making it ideal for dynamic memory management tasks.
Demand paging loads memory pages into RAM only when they are needed, thus optimizing memory utilization and maintaining efficient system performance.
