COMPUTER FUNDAMENTALS

Detailed explanation-1: -Disk fragmentation causes files on your computer to be scattered on different parts of the disk. This usually happens when you install some application or delete a large number of files. When the files are stored in a contiguous space on the hard disk, the system must do extra work to retrieve files from the disk.

Detailed explanation-2: -Disk defragmentation is necessary for Windows PCs because fragmentation is a natural occurrence when files are constantly resized, deleted, and written. So the file spreads across various locations, resulting in the computer taking a long time to read and write data.

Detailed explanation-3: -A fragmented disk takes longer to ‘read from’ and ‘write to’, making a computer run slower. This is where defragmentation’ software is useful. Defragmentation software reorganises the data on the hard drive and puts the fragmented files back together. It also moves files to collect all the free space together.

Detailed explanation-4: -Fragmentation eventually causes your computer to slow down. It forces your hard drive to work harder than it would if files were organized efficiently, and if your hard drive is working overtime then in theory it could wear out faster than it would under more ideal circumstances.
