Answer:

Physical / Data link layer

Explanation:

If two computers (A & B) are directly connected through Ethernet cable. A is sending data to B, the data would be transmitted if the network is clear but if the network is not clear, the transmission would wait until the network is clear.

The Open Systems Interconnection model (OSI model) has seven layers each with its own function.

The physical layer is the first layer responsible for data transmission over a physical link. The data packets are converted to signals over a transmission media like ethernet cable.

The data link layer is the second layer in the OSI layer responsible for transmission of data packets between nodes in a network. It also provides a way of detecting errors and correcting this errors produced as a result of data transmission.

love history [14]

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))
