From the code you posted, there is no function call to vendingMachine()
Try at the top of your code:
print ("hello")
vendingMachine()
def vendingMachine():
...
Answer:
a = 6, b = 0
Explanation:
The loop ran 3 times before b == 0. "while ((b != 0)" is essentially saying: 'While b is not equal to 0, do what's in my loop'. Same general thing with "&& ((a / b) >= 0)". The "&&" is specifying that there should be another loop condition, while the rest states: 'as long as a ÷ b is greater than 0, do what's in my loop'. If both of these conditions are met, the loop will run, It will continue this until the conditions are not met. Hope that helped! :)
In traditional programming, probably the most often used error-handling outcome was to terminate the program in which the offending statement occurred.

Answer:
The answer is "For the stop and wait the value of S and R is equal to 1".
Explanation:
- As we know that, the SR protocol is also known as the automatic repeat request (ARQ), this process allows the sender to sends a series of frames with window size, without waiting for the particular ACK of the recipient including with Go-Back-N ARQ.
- This process is mainly used in the data link layer, which uses the sliding window method for the reliable provisioning of data frames, that's why for the SR protocol the value of S =R and S> 1.
Answer:
<u>d. Statement A is true and Statement B is false</u>
Explanation:
Indeed, when using duplex transmission either node can transmit while the other node can receive data from the network. Also, in half-duplex transmission, both the nodes can transmit as well as receive data.
However, in half-duplex transmission, the nodes <em>cannot </em>transmit and receive data at the same time. Hence, this makes Statement B false, while Statement A is true.
