Everything will be stored in a Hard drive, When you write anything or when you copy any data or when you store any data. The computer will not store the entire data as a single file. It will split data into multiple data packets. It is called fragmentation. Computers store all these fragmented packets in multiple places on the hard disk. The computer may store some packets in the middle of the hard disk or at the end of the hard disk.

When you retrieve data, or when you want to read data, the computer will search for all the packets in the hard drive and accumulates packets into a single file. So it takes some time to search hard disk so that the computer will become slow. While the computer searching for packets in the hard disk, the hard disk has to spin for a long time. So it consumes battery also.

When you run disk defragmentation, the computer will collect all packets for particle files and arrange them in a sequence by removing empty places. So that it will retrieve the data quickly.
