format as either a one or zero (called a bit). Eight of these bits together are most commonly called a byte. Storage capacity is measured by a prefix to the B (byte) to represent a specific amount, ie K (Kilobyte), M (Megabyte), G (Gigabyte), T (Terabyte) etc. Since all computers are based on the binary system, these prefixes represent base 2 amounts. Each level is an increment of 2 to the 10th power or 1,024.
