Both internal and external fragmentation are two types of computer memory processes. One of the main differences between them is the dispersion of memory blocks. Internal fragmentation has memory blocks that are dispensed during the computer memory process, while external fragmentation does not have memory blocks dispensed. When memory is split into these memory blocks, this is when internal fragmentation occurs. External fragmentation happens when the memory has enough to execute the request. However, this request can not be carried out because the memory is not able to be transmitted. When external fragmentation happens, the only way to solve it is with segmentation.

Fragmentation is a process that occurs in computer memory. The difference between internal fragmentation and external fragmentation is that an internal fragmentation fixed-sized memory blocks are dispensed in the process.

Internal fragmentation occurs when the memory is split into mounted sized blocks. Whenever a method request for the memory, the attached sized block is prearranged to this method. External fragmentation occurs when there is an adequate amount of area within the memory to satisfy the memory request of a method.

However, the process’s memory request cannot be satisfied because the memory available is during a non- transmittable manner. The solution to internal fragmentation is the best-fit block. The solution to an external fragmentation is segmentation.
