Memory - (Byte|Word) Addressable - Storage size of an address

Card Puncher Data Processing

About

The type of data retrieved by an memory address may be:

Type

Byte

Byte addressing means memory is organized and accessed as a sequence of bytes. Whether one or more bytes are being accessed, a byte address is used to locate the byte or bytes memory.

The range of memory that can be addressed is called an address space.

wiki/Byte-addressable where each address identifies a single byte of storage. Most of the modern computer are byte addressable.

Word

The largest possible storage size for an address is a word and we talk about a wiki/Word-addressable memory where each address identifies a single word of storage.
