Unit 5 assignment 1 and definitions When performing a cable installation‚ there are a lot of things that you have to put into consideration. First‚ you want to draw up a plan. Some things that you would want to include in the plan would be: where your telecommunications rooms are located‚ what is the distance from your leased line to your core router‚ and what type of cable are you going to be using for your backbone and horizontal lines. The first thing shouldn’t be cost when you are designing

1 What are two reasons for physical layer protocols to use frame encoding techniques? (Choose two.) to identify where the frame starts and ends* to distinguish data bits from control bits* to reduce the number of collisions on the media to increase the media throughput to provide better media error correction 2 Which statement is correct about multimode fiber? Multimode fiber commonly uses a laser as a light source. Multimode fiber cables carry signals from multiple connected sending

centrality[1] Degree centrality shows how much a node connected with other nodes. For a node if more the number of direct connections with other nodes more the Degree centrality will be. Greater Degree centrality supports the chances of node to be active. To calculate Degree centrality let N is the set of all nodes in the network ‚ Degree centrality Cd of any node i then where (i‚ j) representing a link between node i and node j. n is the total number of nodes in the network. In figure 1 node C will
