In laptop architecture, a word is a unit of data of an outlined bit size that might be addressed and moved between storageand the pc processor. Usually, the outlined bit size of a word is equivalent to the width of the pc’s knowledge bus in order that a word can be moved in a single operation from storage to a processor register. For any pc architecture with an eight-bit byte, the word will be some a quantity of of eight bits. In IBM’s evolutionary System/360 architecture, a word is 32 bits, or 4 contiguous eight-bit bytes.
