What do you understand by the term ‘structured cabling’. State the main rules that should be used when installing a cable. 31. Show that maximum cabling area for LAN for horizontal cabling runs is approximately 200m.3
What are the various classes of IP addressing? Calculate the maximum number of class A, B and C network Ids.3

How does a token ring network work ? In what way is it different from Ethernet ?
Explain Difference between congestion control and QoS(or Quality of service)
Why is a data link layer switch preferred over a hub ?
The physical layer service is a non-confirmed service. Assume that some bits of data are lost during transmission over physical media, which layer will detect the loss and take some remedial measures. Explain any one method clearly depicting how this operation is performed.
