Obviously as Computer can find what it needs faster it keeps computer from getting sluggish trying to find Files.

Defragmenting does not change how things work. It just improves access speeds for some files.
Imagine a file which occupies sectors 1000, 1001, 89975438, 899754389, 902 and 903.
Moving the data around so that the sectors are all in a row means that the heads don't have to zoom forwards and backwards, which is the slowest operation on a disk drive.

Windows 7 defragments drives on a timer, usually set to the middle of the night; Windows 8 and 10 do it automatically when the machine is idle.

If you have a solid-state drive, defragmenting doesn't improve speeds; it takes the same amount of time to reach any sector. Indeed, it wears out the drive as flash memory can survive only a limited (if large) number of cycles. Windows 8.1 and 10 are usually able to spot solid-state drives and disable automatic defrag.
