The Binary Number System docsity.com • A single unit of data is called a bit, having a value of 1 or 0. • Computers work with collections of bits, grouping them to represent larger pieces of data, such as letters of the alphabet. • Eight bits make up one byte. A byte is the amount of memory needed to store one alphanumeric character. • With one byte, the computer can represent one of 256 different symbols or characters. .
