instruction: What is a byte?
context: The byte is a unit of digital information that most commonly consists of eight bits. Historically, the byte was the number of bits used to encode a single character of text in a computer and for this reason it is the smallest addressable unit of memory in many computer architectures. To disambiguate arbitrarily sized bytes from the common 8-bit definition, network protocol documents such as the Internet Protocol (RFC 791) refer to an 8-bit byte as an octet. Those bits in an octet are usually counted with numbering from 0 to 7 or 7 to 0 depending on the bit endianness. The first bit is number 0, making the eighth bit number 7.
response: A byte is a unit of digital information consisting of eight bits (typically). Historically, a byte was the number of bits needed to encode a single character of text in a computer. Because of this, a byte is the smallest unit of. memory in many computer architectures.
