Computer Networks

i up load the workshop as ZIP and it's has 2 file one the assignment and the other is the last year assignment and the solution it;s may help you this assignment is Computer Networks. 2. The address resolution protocol (ARP) is used to resolve a layer 3 address to its corresponding layer 2 address. a. Why is an ARP query sent within a broadcast frame? (2 points) b. Why is an ARP response sent within a frame with a specific destination MAC address? (2 Points) 3. Ethernet uses the CSMA/CD multiple access protocol. a. Discuss the features of this protocol that enable collision-free operation when there are multiple traffic sources contending for the use of a given link. (5 points) b. With the CSMA/CD protocol, the adapter waits K x 512 bit times after a collision, where K is drawn randomly. For K =100, calculate how long the adapter waits before sensing the channel for 10Mbps Ethernet and 100 Mbps Ethernet? (4 points)
