Frag to the dee

One of your associates used the Windows “defrag” command to increase the performance of his computer. What does the defrag command actually do?

A) Creates contiguous files in memory for faster access

B) Rearranges files on disk to increase read performance

C) Modifies the video memory for faster refresh rates

D) Separates running processes into smaller pieces for faster performance through multi-core CPUs

E) Makes the mice run faster inside of the wheel

The answer: B) Rearranges files on disk to increase read performance

One of the slowest devices in your computer is the mechanical hard drive. The defragmentation process moves pieces of files around until the entire file is contiguous, minimizing the amount of time the mechanical head must search for parts of a file.
