I don't think some will write the whole program here, but which part are you having trouble with?
Answer:
Syntax error
Explanation:
This is a type of error that occurs when there is a problem with the code that makes it unable to compile and execute.
For example, making a conditional statement without using the correct parameters will result in a syntax error.
The program is correct: at the beginning, product = 0. Then, we start summing Y to that variable, and we sum Y exactly X times, because with each iteration we increase Count by 1, and check if Count=X so that we can exit the loop.
Answer:
QoS
Explanation:
We could use a blacklisting or a MAC filtering to remove from the network, and in this way, we're going to get a high portion of bandwidth, but other must work too, and the whitelisting have almost the same function, but QoS Quality of service is specifically for these cases where we need high bandwidth for a video conference, we can make this with some tools or techniques like jitter buffer and traffic shaping.
