Nt1330 Unit 3 Exercise 1 Essay
Exercise 2.3.1
LAN – Local Area Network – within a building
MAN – Metropolitan Area network – larger than a LAN, smaller than a WAN
PAN – Personal Area Network – less than 30 feet
WAN – Wide Area Network – collection of LANs geographically spread over large distance
Exercise 2.3.2
Network Topology – A drawing of a series of connected nodes via links, including descriptions.
Exercise 2.3.3
It would take 1 (hop) message to send a message from node A to node B. It would take 3 (hop) messages to send a message from node B to node A. One additional link is required to add a new node E between node C and node D. With the new node added, the number of messages to Travers from node B to node A would increase by one.
Exercise 2.3.4 …show more content…
It would take 3 (hop) messages to send a message from node D to node A. One additional link would be required to add a new node E between node C and node B. The added node E will increase the number of actual messages required to be sent form one node to another.
Exercise 2.3.5
There are three messages that are sent from the hub to node B when node A sends a message to node B in the Star Topology. One message is sent from the switch to node B when node A sends a message to node B.
If a hub is the central device used when adding a new node D then another message is sent for a total of four messages sent from the hub when a message is sent from node A to node B. However, there is no change to in the number of messages sent on the network when the central device is a switch, it is still one message.
Exercise 2.3.6
Three messages are necessary to send a message from node A to node D. Three messages are also necessary to send a message from node A to node B.
Four new links are required to add a new node E between node C and node D. Five new links would be required to add a new node F.
