Binary number 100100 (36 decimal). When computers must add two numbers, the rule that: x xor y = (x + y) mod 2 for any two bits x and y allows for very fast calculation, as well. A simplification for many binary addition problems is the Long Carry Method or Brookhouse Method of Binary Addition. This method is generally useful in any binary addition in which one of the numbers contains a long "string" of ones. It is based on the simple premise that under the binary system, when given a "string" of digits composed entirely of ones ("where:" is any integer
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
