Beyond Bits and Bytes
The smallest unit of computer memory is a bit. A bit is basically on/off switch and is usually described as a 1 or 0. A byte is a pattern of 8 bits. A byte is smallest amount of memory needed to encode an alphanumeric character such as A-Z or 0-9. Additional units of memory are defined by powers of 2.

1 kilobyte (1K) = 1,024 bytes
(1,024 = 2^10)

1 megabyte (1MB) = 1,024K = 1,048,576 bytes
(1,048,576 = 2^20)

1 gigabyte (1GB) = 1,024MB = 1,073,741,824 bytes
(1,073,741,824 = 2^30)
