1. In considering the Von Neumann architecture, describe in English the process that the CPU must undertake to read a value from memory and to write a value from memory and to write a value to memory in terms of what is put into the MAR, MBR, address bus, data bus, and control bus. [5 marks]
2. Suppose that the following instructions are found at the given location in memory: [5 marks]

0040H LOAD 0060H
0041H MULT 0061H
0042H STORE 0061H
0060H 20
0061H 12
