3. The PC gets incremented _____________
a) After the instruction decoding
b) After the IR instruction gets executed
c) After the fetch cycle
d) None of the mentioned
View Answer
Explanation: The PC always points to the next instruction to be executed.
4. Which register in the processor is single directional?
a) MAR
b) MDR
c) PC
d) Temp
View Answer
Explanation: The MAR is single directional as it just takes the address from the processor bus and passes it to the external bus.
