A bit string can also be referred to as a binary code, bit array, or binary sequence. It is a sequence of binary digits consisting of the numbers 0 and 1. Another synonym for bit string is bit pattern, which represents a sequence of bits that have a specific structure and can be used to represent encoded information. Additionally, bit string can be interchangeable with the term digital fingerprint, which is used to identify and compare digital data. The term bitstream is also used to refer to a contiguous sequence of bits that represent digital information. Finally, a bit-string can also be called a bit vector, which is a mathematical term used to represent a collection of binary values or flags.
