Answer #1

4) False

Explanation: 8 x 1 multiplexer has 3 select lines i.e 2^3 = 8

5) False

Explanation: 0x4000 , AS INSTRUCTION is 4 bits. So 0x4000 + 4 = 0x4004 as the next instruction

6) False

Explanation: Number of operands depends on the type of instruction Like ADD will take 2 operands.

7) False

Explanation: Interrupt driven is better than polling

8) True

Yes, multiple pointer can point to same variable.,

Thanks, PLEASE COMMENT if there is any concern.
