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.

It would take 3 (hop) messages to send a message from node A to node D.
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.

2 A Star Topology with a central device could cause a single point failure. Similarly, any one node on a Ring Topology will cause a total failure.
3. Mesh networks limiting factors could be the justification for money spent on multiple NIC (i.e. multiple Ethernet cable ports) and the cable connections (Links) cost Star networks limiting factors are the switch or hub’s limitation on the number of cable links and the bandwidth limitations.
4. An example of a MAN (Metropolitan Area Network) could be the devices used and networked to allow the NY Subway to function and communicate properly.
