Storage in C programs is made up of units called @dfn{bytes}. A byte
is the smallest unit of storage that can be used in a first-class
manner.
On nearly all computers, a byte consists of 8 bits. There are a few

systems) where a byte is longer than that. This manual does not try
to explain the peculiarity of those computers; we assume that a byte
