E. Answer the following questions:
1. In which network all nodes are situated in a small area?
Answer: In Local Area Network(LAN) all nodes are situated in a small area.
2. What is the name given to a network in which nodes are spread in a city?
Answer: In Metropolitan Area Network(MAN) all nodes are spread in a city.
3. What is the name given to a network in which nodes may spread in many countries?
Answer: In Wide Area Network (WAN) all nodes may spread in many countries.
4. What do you mean by the network topology? Explain its kinds.
Answer: Topology of a network means the structure of that network.
F. Explain the advantages and disadvantages of:
1. Ring topology
2. Star topology
Answer:
Advantages of Ring topology:
* In a ring topology, the flow of data is in one direction only.
* The ring works well where there is no central site computer system.
Disadvantages:
* In ring topology, in case one node fails the whole network fails.
Advantages of Star topology:
* It is easier to construct a star network.
* If any of the local computer fails, the remaining portion of the network is unaffected.
Disadvantages:
* When the central hub or switch fails, all the nodes attached shut down.
