In a memory architecture where each addressable unit is a single byte, this memory is described as:

• A. Byte Addressable Memory
• B. Word Addressable Memory
• C. Bit Addressable Memory
• D. Nibble Addressable Memory

Answer: (A)

The key idea here is how memory is addressed: the addressable unit is the smallest chunk that can be accessed directly. If every address points to a single byte, the memory is byte-addressable. You move from one address to the next byte by incrementing the address, regardless of how much data a location can hold. If the unit were a word (often 2 or 4 bytes), it would be word-addressable; if the unit were a single bit or a nibble (4 bits), it would be bit-addressable or nibble-addressable, respectively. Since the given condition specifies a single-byte addressable unit, this memory is byte-addressable.
