Data Size Information

The capacity of a computer hard disk drives and the files it contains can be confusing. Below is a listing of the standards in different size values. It is important to realize that not all manufacturers and developers use these values. For example, a manufacturer may consider a gigabyte as the value of a gibibyte.

Bit Value of 0 or 1
Nibble: 4 Bits
Byte: 8 Bits
Kilobit: 1,000 bits
Kilobyte: 1,000 bytes
Kibibit: 1,024 bits
Kibibyte: 1,024 bytes
