Disk Space

Alternatively referred to as disk space, disk capacity is the total amount of bytes that a disk drive or disc is capable of holding. Typically, the storage device is the computer’s hard drive, but it can also be a USB thumb drive, a CD or DVD, a memory stick/card, or a floppy disk. Disk space is usually measured in kilobytes (KB), megabytes (MB), gigabytes (GB), or terabytes (TB). For example, a hard drive that is 500 GB is capable of holding 500 Gigabytes of information.
