The Computer Dictionary

Bit
b

A single unit of data.  A bit is either 1 or 0 in a binary numeral; it is the smallest unit of information handled by a computer. The word comes from the term, "binary digit."

A typical page of text will have about 16,000 bits. Because eight (8) bits make a byte, that same page of text will have about 2,000 bytes. 

Note: In reference to digital data, a small "b" refers to bits, and a capital "B" refers to bytes.
