Kilobyte

The kilobyte is a multiple of the unit byte for digital information. Although the SI prefix kilo- means 1000, the term kilobyte and symbol KB have historically been used to refer to either 1024 (210) bytes or 1000 (103) bytes, dependent upon context, in the fields of computer science and information technology.For example, when referring to data transfer rates and to disk storage space, "kilobyte" means 1000 (103) bytes. On the other hand, random-access memory capacity such as CPU cache measurements are always stated in multiples of 1024 (210) bytes, due to memory's binary addressing.In the International System of Quantities, the kilobyte (symbol kB) is 1000 bytes. The binary representation of 1024 bytes typically uses the symbol KB, using an upper-case K. Informally sometimes the B is dropped, making K generally understood as 1024 bytes; however, this usage is not standardized and may be found used arbitrarily. All existing recommendations prefer to use the uppercase letter B for byte, because b is used for the bit.
