Eight bits grouped together. One byte can hold any number from 0 to 255 — enough for a single letter or symbol.
A group of 8 bits, capable of representing 256 distinct values. Bytes are the smallest addressable unit in most CPU architectures and the basis for character encodings like ASCII and UTF-8.
Historically variable-width on early architectures; standardized to 8 bits (an octet) by IEEE 1541. Memory addresses index bytes; word size, alignment, and endianness determine how multi-byte values are laid out and accessed.
