The kilobyte is a multiple of the unit byte for digital information. A kilobyte may refer to either 1000 or 1024 bytes. The International System of Units (SI) defines the prefix kilo as a multiplication factor of 1000 (10 3); therefore, one kilobyte is 1000 bytes. [1] The internationally recommended unit symbol for the kilobyte is kB. [1]
The difference is a direct result of the sizes of the values used to report the amounts of total and unallocated (free) extended memory in 1 KB (1024-byte) units: XMS 2.0 uses 16-bit unsigned integers, capable of representing a maximum of (65535 * 1 KB) = 64 MB, while XMS 3.0 adds new alternate functions that use 32-bit unsigned integers ...
In the context of computing, the metric prefixes are often intended to mean something other than their normal meaning. For example, 'kilobyte' often refers to 1024 bytes even though the standard meaning of kilo is 1000. Also, 'mega' normally means one million, but in computing is often used to mean 2 20 = 1 048 576. The table below illustrates ...
The enhanced DOS command line processor 4DOS 3.00 supports a number of additional conditions (DISKFREE, DOSMEM/DOSFREE, EMS, EXTENDED, FILESIZE and XMS) in IF commands, which allow to test for sizes in bytes, kilobytes (by appending a K) or megabytes (by appending an M), where 1 K is defined as 1024 bytes and 1 M is defined as 1024 × 1024 bytes.
An alternative system of nomenclature for the same units (referred to here as the customary convention), in which 1 kilobyte (KB) is equal to 1,024 bytes, [38] [39] [40] 1 megabyte (MB) is equal to 1024 2 bytes and 1 gigabyte (GB) is equal to 1024 3 bytes is mentioned by a 1990s JEDEC standard. Only the first three multiples (up to GB) are ...
A group of 8 bits (8 bit) constitutes one byte (1 B). The byte is the most common unit of measurement of information (megabyte, mebibyte, gigabyte, gibibyte, etc.). The decimal SI prefixes kilo, mega etc., are powers of 10. The power of two equivalents are the binary prefixes kibi, mebi, etc. Accordingly: 1 kB = 1000 bytes = 8000 bits; 1 KiB ...
The 5.25-inch diskette sold with the IBM PC AT could hold 1200 × 1024 = 1 228 800 bytes, and thus was marketed as "1200 KB" with the binary sense of "KB". [40] However, the capacity was also quoted "1.2 MB", [41] which was a hybrid decimal and binary notation, since the "M" meant 1000 × 1024.
