Question 1 [5 Marks]
Carrier Sense Multiple Access/Collision Detection (CSMA/CD) is an access method used with the Ethernet.
Discuss how CSMA/CD will work with an Ethernet switch when 10baseT is implemented in some network. How
collisions are managed by an Ethernet switch?
Question 2 [10 Marks]
Given the two polynomials x9+x7+x4+x3+x2+x and x3+x+1. Consider 1st polynomial as dividend and 2nd as
divisor. You are required to perform the following tasks:
· Convert both polynomials into binary equivalents.
· CRC will consist of how many bits, mention.
· Find the CRC value of these binary equivalents with each step written in your solution.
