Answer:
Physical and data link layer.
Explanation:
The ethernet cable is used at the physical layer. The physical layer consists of hardware components. This layer is responsible for transmission of data bits between two nodes via a physical wire. The data link layer provides the means in which data packets are transmitted from one node to another.
Suppose two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the packets would be sent from computer A to computer B if computer B is free if not it would wait until computer B is not transmitting before it can start sending data packets to computer B.
This can be done in a number of steps.

Answer:
Explanation:
The following code is a Python function that takes in the amount of change. Then it uses division and the modulo operator to calculate the number of coins that make up the changes, using the greatest coin values first.
import math
def amountOfCoins(change):
print("Change: " + str(change))
quarters = math.floor(change / 0.25)
change = change % 0.25
dimes = math.floor(change / 0.20)
change = change % 0.20
pennies = math.floor(change / 0.01)
print("Quarters: " + str(quarters) + "\nDimes: " + str(dimes) + "\nPennies: " + str(pennies))
