Answer:

Explanation:

According to my research on information technology, I can say that based on the information provided within the question the longer the distance of a telephone wire between sender and recipient, the lower the bandwidth across that wire. This is because bandwidth is the amount of information that passes through the cable and the quality of it. The longer a cable is the more packet loss that will occur as well as having a high probability of transmission errors occurring.

There is a stack call created in the memory whenever a function is called.

LOOP :

Whereas the number of times that the loop has to be executed must be defined

A loop cannot be called, it can be used only the code block in which it is present.

There is not overhead of creating a stack since it is not invoked and there is no transfer of control from one module to another
