A bootable device is, as the name suggests, any storage device that the computer can "boot" from. In this case the word "boot" refers to the loading of the operating system. So any device you can load an operating system from is a bootable device.
In modern computers, the hard disk is generally the primary boot device. However most new computers can also boot from a CD-ROM or DVD drive (usually for the purpose of reinstalling an OS to the hard disk) so it is also a bootable device. Many systems also have the ability to boot from USB thumb drives or external hard disks and back in caveman days, floppy disk drives were also popular boot devices.
