A drive, C drive, D drive, E drive, etc. It can be for floppy disks, for CD's, DVD's, memory sticks, or whatever else. Typically the C drive is just your built-in hard drive where your operating system and many other programs for basic operation of your computer are stored. To find it, go to start (lower left of the screen), my computer, and then just click on the C drive icon (Local Disk C:).
