Question

In the context of memory management, what are placement and replacement algorithms?

Answer 1

Placement algorithms determine where in available real-
memory to load a program. Common methods are first-fit,
next-fit, best-fit. Replacement algorithms are used when
memory is full, and one process (or part of a process)
needs to be swapped out to accommodate a new program. The
replacement algorithm determines which are the partitions
to be swapped out
