Kilobyte. The kilobyte is a multiple of the unit byte for digital information . The International System of Units (SI) defines the prefix kilo as a multiplication factor of 1,000 (10 3 ); therefore, one kilobyte is 1,000 bytes. [1] The internationally recommended unit symbol for the kilobyte is kB. [1]
Definition of prefixes using powers of 10—in which 1 kilobyte (symbol kB) is defined to equal 1,000 bytes—is recommended by the International Electrotechnical Commission (IEC). [28] The IEC standard defines eight such multiples, up to 1 yottabyte (YB), equal to 1000 8 bytes. [29]
In digital computing and telecommunications, a unit of information is the capacity of some standard data storage system or communication channel, used to measure the capacities of other systems and channels. In information theory, units of information are also used to measure information contained in messages and the entropy of random variables.
File size. File size is a measure of how much data a computer file contains or, alternately, how much storage it consumes. Typically, file size is expressed in units of measurement based on the byte. By convention, file size units use either a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte ).
Data-rate units. In telecommunications, data transfer rate is the average number of bits ( bitrate ), characters or symbols ( baudrate ), or data blocks per unit time passing through a communication link in a data-transmission system. Common data rate units are multiples of bits per second (bit/s) and bytes per second (B/s).
t. e. A binary prefix is a unit prefix that indicates a multiple of a unit of measurement by an integer power of two. The most commonly used binary prefixes are kibi (symbol Ki, meaning 210 = 1024 ), mebi (Mi, 2 20 = 1 048 576 ), and gibi (Gi, 2 30 = 1 073 741 824 ). They are most often used in information technology as multipliers of bit and ...
Orders of magnitude (data) An order of magnitude is usually a factor of ten. Thus, four orders of magnitude is a factor of 10,000 or 10 4 . This article presents a list of multiples, sorted by orders of magnitude, for units of information measured in bits and bytes . The byte is a common unit of measurement of information ( kilobyte, kibibyte ...
