External Fragmentation: External Fragmentation happens when a dynamic memory allocation algorithm allocates some memory and a small piece is left over that cannot be effectively used. If too much external fragmentation occurs, the amount of usable memory is drastically reduced. Total memory space exists to satisfy a request, but it is not contiguous.

Internal Fragmentation: Internal fragmentation is the space wasted inside of allocated memory blocks because of restriction on the allowed sizes of allocated blocks. Allocated memory may be slightly larger than requested memory; this size difference is memory internal to a partition, but not being used

Compare Contiguous memory allocation with internal fragmentation?

in early, computer system has contiguous memory allocation,each process is allocated in a single contiguous(together) memory!!(allocating into memory addresses one by one,)it has tackled memory fragmentation(both internal and external). not allocating for a fixed size memory block.so no internal fragmentation, allocating contiguously ,so no external fragmentation!!!


What is the difference between external fragmentation and internal fragmentation in memory management?

External fragmentation occurs when free memory blocks are scattered throughout memory, making it difficult to allocate contiguous blocks of memory to processes. Internal fragmentation, on the other hand, happens when allocated memory is larger than what is actually needed, leading to wasted space within memory blocks.


Difference between internal fragmentation and external fragmentation in operating system?

Fragmentation occurs in a dynamic memory allocation system when many of the free blocks are too small to satisfy any request.

What is the difference between internal and external fragmentation in OS?

Internal Fragmentation is the area in a region or a page that is not used by the job occupying that region or page. This space is unavailable for use by the system until that job is finished and the page or region is released.
