Internal is normally dedicated to the phone and it's OS. For such use as adding more apps, texts, contacts. External is more pointed at using it for your own personal media. although on smartphones you can point apps to be loaded from the external memory. other factors are if you can take the memory out of the phone. Internal meaing you can't and External meaning you can. This is normal in the format of a memory card. (SD, Micro SD etc)

They have a limited amount of internal memory - enough to allow the phone to perform all the tasks available to make it function. Additional memory is added at the choice of the user. Due to the fact that technology lasts much longer these days, a user might have a phone for many years. This means the company 'loses out' once the phone has been purchased. Having the ability to add extra memory - creates additional income for the manufacturer.

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!!!


Definition of internal fragmentation and external fragmentation?

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
