HOW TO FIX DISK FRAGMENTATION on our PC ?

Solution :: 1st part.

 Refers to the order of a disk in which files are separated into pieces dotted around the disk. Fragmentation occurs logically when you apply a disk frequently, creating, deleting, and modifying files. At a few point, the operating system wants to store parts of a file in noncontiguous clusters. This is entirely hidden to users, but it can slow down the pace at which data is accessed be cause the disk drive have to search through different parts of the disk to put jointly a single file.

 Fragmentation can also refer to RAM that has little, unused holes dotted throughout it. This is called external fragmentation. With modern working systems that use a paging system, a more common type of RAM fragmentation is internal fragmentation. This occurs when memory is billed in frames and the frame size is better than the amount of memory requested.

TO FIX DISK FRAGMENTATION YOU HAVE TO DO DEFRAGMENTATION. WHAT DID YOU SAY DEFRAGMENTATION?

 Defragmentation is the course of locating the noncontagious/dotted fragments of data into which a computer file may be separated as it is stored on a hard disk, and rearranging the fragments and restoring them into less fragments or into the whole file on PC.

Defragmentation reduces data contact time and allows storage to be used more professionally. Some working systems mechanically defragment storage occasionally; others require that the user occasionally use a particular utility for this purpose. "Defrag" is a little form of the verb to defragment and sometimes the name of the utility used for defragementing, which is also called a defragmenter.
