keeps track of memory location to prevent data and programs from overlapping each other

swaps portions of programs and data into the same memory but at different times

keeps track of virtual memory

17
Q

Queue

A

First in, First out (FIFO) sequence of data or programs that waits in line for its turn to be processed

18
Q

buffer

A

the place where the data or programs sit while they’re waiting to be processed
