Space management problem can be solved in two approaches:

Segmentation - chop into variable-sized pieces .
drawback : when space is divided into different sized chunks, the space itself gets fragmented, and thus allocation becomes challenging over time.
Paging - chop up space into fixed-sized pieces .
Instead of diving space into code, heap, stack, we divide space into fixed sized units we call a page.
View the physical memory as array of fixed size slots called page frames. Each frame contains one virtual memory page.
