Answer:
The code requests for the scores of three students for three courses offered by each student.
It calculates and print the average score for each student
Explanation:
The code written in Python programming language uses a while to get student 1-3 and a for loop to get scores for course 1-3
See attached code and output
Waiting time for a 100 Mbps broadcast channel is 0.512 ms
Recall that with the CSMA/CD protocol, the adapter waits K * 512 bit times after a collision,
where K is drawn randomly. For K = 100,
The one bit time for 10 Mbps is 1/10000000 s = 0.0001 ms
The one bit time for 100 Mbps is 1/100000000 s = 0.00001 ms
Waiting time for a 10 Mbps broadcast channel is K*512*0.0001= 5.12 ms
Waiting time for a 100 Mbps broadcast channel is K*512*0.00001= 0.512 ms

What is a collision in Ethernet?</h3>
- A collision happens on a half-duplex Ethernet network when two devices on the same network attempt to communicate data at the exact same time.
- The two transmitted packets are "collapsed" by the network, which results in the network discarding both of them.
- On Ethernets, collisions are unavoidable.
- A collision is a momentary interaction between two bodies or more than two bodies at once that modifies the motion of the bodies involved as a result of the internal forces at work.
- Collisions entail the application of force (there is a change in velocity).
