Answer 1

The phenomenon of less-than-complete use of memory space in a fixed partition is called internal fragmentation.

Answer 2

The answer to the question above is INTERNAL FRAGMENTATION. This is related to computer memory space. Basically, when we say fragment, this refers to the memory space's hole which resulted from the removal from the physical memory block. Fragmentation comes in two categories: internal and external. Talking about internal fragmentation, this only happens when the memory is splits into "fixed size blocks or partition".
