It resides in the Disk(hard disk).
Unused disk space is space on a hard drive (or another kind of disk such as a CD) which has not had any digital information written onto it or is free to be written over. Example: you buy a brand new 100GB hard drive and the only thing on it is your copy of Windows7 64-bit. About 20 GB of the hard drive are required to store the Windows7 operating system on, so you would have around 80GB left that is "free." This is unused disk space. An interesting fact, too: when you delete something by putting it into your "recycle bin" and deleting it, it doesn't actually "go" anywhere. The computer does not go in and actually "erase" that information from your hard drive, it just notes that the area where that information was stored is now "free" to be written over with new information, so this also counts toward "unused disk space."

The typical storage size for a hard disk is 160GB. A hard disk that has 160 gigabytes of space can allow the computer users to store music, videos, documents and photos without straining the computer.
Recycle Bin
Recycle bin is an icon on the Windows desktop that represents a directory where deleted files are temporarily stored. This enables you to retrieve files that you may have accidentally deleted. From time to time, you'll want to purge the recycle bin to free up space on your hard disk. You can also configure Windows so that it doesn't use the recycle bin at all, but then you won't be able to retrieve accidentally deleted files. Items in the Recycle Bin remain there until you decide to permanently delete them from your computer. These items still take up hard disk space and can be undeleted or restored back to their original location. When it fills up, Windows automatically cleans out enough space in the Recycle Bin to accommodate the most recently deleted files and folders.
