. The unit is generally expressed in MB and B. The addressing range in this question is 0 ~ 2 ^ 20-1, addressing space is 1 MB. 2. byte addressing refers to the smallest unit of addressing a bucket in bytes and the word-based addressing refers to the smallest unit of addressing a bucket in words. For example, the total memory capacity is certain, and the number of encodings required by word addressing and byte addressing is different. Because the add
