Binary number numeric values may be represented by two different voltages; on a magnetic disk, magnetic polarities may be used. A "positive", "yes", or "on" state is not necessarily equivalent to the numerical value of one; it depends on the architecture in use. In keeping with customary representation of numerals using Arabic numerals, binary numbers are commonly written using the symbols 0 and 1. When written, binary numerals are often subscripted, prefixed or suffixed in order to indicate their base, or radix. The following notations are equivalent: When spoken, binary numerals are usually read digit-by-digit, in order to distinguish them from decimal
Compound File Binary Format Binary Format is a container, with little restriction on what can be stored within it. A CFBF file structure loosely resembles a FAT filesystem. The file is partitioned into "Sectors" which are chained together with a "File Allocation Table" (not to be mistaken with the file system of the same name) which contains chains of sectors related to each file, a "Directory" holds information for contained files with a Sector ID (SID) for the starting sector of a chain and so on. The CFBF file consists of a 512-Byte header record followed by a number of sectors whose size is
