1. Bits & Bytes A bit is the smallest amount of memory used to store information. A bit is represented by either a “0” or a “1”. “Bit” is a contraction of the term “binary digit”. A byte consists of any combination of 8 bits. It is the amount of memory it takes to store a single character once that character has been converted to its binary equivalent. ex. 0101 1110 = 8 bits = 1 byte of memory storage.

2. Bits & Bytes Relating to electronics and electrical circuits, “0” represents the “off” position of a digital switch, and a “1” represents the “on” position of a digital switch. When a digital switch is “on”, electricity is allowed to pass through a circuit; when a digital switch is “off”, electricity is not allowed to pass through a circuit.
