7-bit

7-bit refers to a numbering system that uses 7 binary digits (bits) to represent numbers and other data. Each binary digit can have two values: 0 or 1. In a 7-bit system, there are 2^7, or 128, possible combinations of 0s and 1s, and each combination can represent a different number, character, or other unit of data. The 7-bit system was commonly used in early computer systems and was the standard for character encoding in the ASCII (American Standard Code for Information Interchange) character set, which includes 128 characters, including letters, numbers, and symbols. Today, most computers and other digital devices use 8-bit or larger systems for character encoding, allowing for a much larger range of characters and symbols to be represented.
