What’s unallocated space?

It happens quite often that there is a part of hard drive that appears to be “Unallocated” or “Free”, which might be rarely known by many users. Unallocated space is in contrast to “allocated space” which is a portion of hard drive and stores data that is viewable to users. The unallocated or free drive space is invisible in Windows Explorer, but that space might be a normal partition containing files and folders before. Here is a screenshot of Disk Management and there is 15GB unallocated space between partition C and E.
