We can represent the memory in two ways:
1) Byte Addressable Memory.
2) Word Addressable Memory.
1) Byte addressable memory: Byte addressable memory is a memory where we address each and every byte.
2) Word Addressable Memory: Here word size is not fixed, maybe 1 word =1 byte or 1 word = 2 byte or 1 word = 4 byte, etc.
Let assume 1 word= 2 byte
Here we assign the address as per word (2 bytes).
We can also represent Word Addressable Memory (WAM) by Byte Addressable Memory (BAM).
Let 1 Word = 2 Byte.
