Solutions

Expert Solution

1. True

Explanation: Multiplexing means sending a stream of multiple signal over a communication link the same time and at the receiver end demultiplexing process is used to seperate the multiplexed signal.

In 8086 microprocessor the address and data bus are multiplexed in AD0 - AD15 to reduce the number of pins required.

2. True

Explanation: PUSHF instruction is used to copy the flag register to the top of the stack

POPF instruction is used to copy the word in the top of the stack to the flag register

3. False

Explanation: CBW instruction is used to convert signed byte into signed word

CWD instruction is used to convert signed word into double signed word

4. False:

Explanation: AND instruction is used to clear one or more bits in a register

OR instruction is used to add one or more bits in a register

5. False

Explanation: In 8086 microprocessor 20 address line and 16 data lines are there.
