Binary Number System

  • Gerard O’Regan


The binary number system (base 2) is a positional number system which uses two binary digits 0 and 1. The binary system is ideally suited to the digital world of computers, as a binary digit may be implemented by an on-off switch. Digital devices that store information or data on permanent storage media such as disks and CDs or temporary storage media such as random-access memory (RAM) consist of many memory elements that may be in one of two states (i.e., on or off).
