To answer these questions you need to remember the powers of $2.$ The power of $2$ equal to the number of rows or columns is the same as the number of bits required to identify the particular row or column.

Assume that the memory on a system is organized as a two$-$dimensional grid with $32768$ rows and $256$ columns. Also, assume that each memory cell is $8-$bits wide. Answer the questions on this page $(1-8)$ based on these facts.

All questions require a numerical answer. Do not use alphabetical characters, spaces or any punctuation.

How many bits are needed for the MAR register on such a system?
