Swapping is when a process is completely put out of
Physical memory to Swap Space when memory is required for
some other process.

Paging is the term used when only a part of this process is
put out of the physical memory to the secondary storage,
with some part of the process still in physical memory.
Since it is only the pages being swapped in and out this
operation is called paging.

Write a command that will display files in the current directory, in a colored, long format.
