Binary erasure channel erasure channel which shares many similar theoretical results with the binary erasure channel. The BEC is a "binary channel"; that is, it can transmit only one of two symbols (usually called 0 and 1). (A non-binary channel would be capable of transmitting more than two symbols, possibly even an infinite number of choices.) The channel is not perfect and sometimes the bit gets "erased"; that is, the bit gets scrambled so the receiver has no idea what the bit was. The BEC is, in a sense, error-free. Unlike the binary symmetric channel, when the receiver gets a bit, it is
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
