Exercise 2.3.1
LAN- Local Area Network is a computer network that interconnects computers within a limited area such as a home, school, computer laboratory, or office building using network media.
MAN-Metropolitan Area network is a computer network in which two or more computers or communicating devices or networks which are geographically separated but in same metropolitan city and are connected to each other are said to be connected on MAN.
PAN- personal area network is a computer network used for data transmission among devices such as computers, telephones and personal digital assistants.
WAN- A wide area network (WAN) is a computer network that spans a relatively large geographical area and consists of two or more interconnected local area networks (LANs).
The classification metric used here
Exercise 2.3.2
Network Topology is the arrangement of the various elements (links, nodes, etc.) of a computer network. Essentially, it is the topological structure of a network, and may be depicted physically or logically. The metric used to define networks by topology is what clients they are using and how they are using them. A wide area network is larger than a metropolitan network for example.
Exercise 2.3.3
It would take 1 hop to send a message from A to B. To get from B to A it would take 3 hops to send a message. It would take one link to connect E to D and C. It would add one message to the transverse of the ring.
Exercise 2.3.4
It would actually take one message to send a message from A to D. The same goes from D to A. It would take one to add node e between C and B. The added node would affect the network by having no initial effect on it.
Exercise 2.3.5
It would take 2 actual messages to send a message from A to B. If the central device is a hub then it would take would take two messages to get from A to B. If using a switch it would take one message to get A to B. The effect of adding a new node between C and D you are creating a bus between C and D. Which creates a Hybrid Star.
Exercise 2.3.6
It would not mater, because in a mesh only one message can be sent between any two points in a mesh topology. Two
