meg·a·byte

(mĕg′ə-bīt′)
1. A unit of computer memory or data storage capacity equal to 1,024 kilobytes (220 bytes).
2. One million bytes.
Usage Usually the prefix kilo- means "one thousand," and the prefix mega- means "one million." But in the calculation of data storage these prefixes have a different meaning. Data storage capacity (measured in bytes) is based on powers of 2 because of the binary nature of bits (1 byte is 8, or 23, bits). Here, the prefix mega- refers to the power of 2 closest to 1,000,000, which is 220, or 1,048,576. Thus, a megabyte is 1,048,576 bytes, although it is also used less technically to refer to a million bytes. Similarly, the prefix kilo- refers either to 1,000 or to 210 (1,024). Measuring the transmission of data is somewhat different from measuring its storage. Since a bit of transmitted data is considered as one signal pulse rather than an either/or unit, it is natural to count transmitted bits using ordinary numbers instead of the binary system. Thus a megabyte of transmitted data usually refers to a million (not 1,048,576) bits. Other prefixes for greater amounts, such as giga- and tera-, follow similar rules for data storage and transmission.
