What is Bit?

VietMX Staff asked 3 years ago

bit is a short for “binary digit”. It is the smallest unit of measurement in computer data. It contains a single binary value of 0 or 1. A single bit can define a boolean value of True (1) or False (0), but in computer memory, bits are often grouped together in 8-bit clusters called bytes.

Since a byte contains eight bits that each have two possible values, a single byte may have 28 or 256 different values.
