While trying to recall a list of items in correct order, the tendency to remember the first items in the list is called while the tendency to remember the last items in the list is called

The primary effect, the recency effect

Explanation:

The first item in the list can be transferred to the long term memory and distinguishing the first items in the list is called primary effect.

Remembering the last item in the list is the recency effect and is associated with  in the short term memory.

answer: internal fragmentation is the difference between the (fixed) size of a memory hole and the data within in that memory. for example, if a 1,024 byte block of memory holds 800 bytes of data, then the 224 bytes difference is considered lost to internal fragmentation.

external fragmentation occurs when the sum of memory fragments is large enough to satisfy a request, but the holes are non-contiguous and the request cannot be satisfied. this can occur when memory is dynamically allocated and freed.
