Well, as the name suggests, disk defragmentation sounds something like putting back the broken pieces together. In terms of PC management, it deals with picking up all the pieces of data spread across your hard drive and bringing them together.

Most PC hard drives have spinning patterns and they store data in different places. While writing some new data, blocks are created that are sequentially ordered. When a file gets split between different far away blocks, fragmentation occurs. As a result, read heads take much longer to read that file.
