QUESTION: - 1
Suppose a leather firm wants to build a computer network, where it wants to connect, which topology you will prefer to connect multiple star topologies? Explain your answer with solid reasons.
ANSWER:-
According to my opinion I will prefer the tree topology to connect the given multiple star topology together. Best topology for branched out networks is tree topology. The reasons are given below that why I use the tree topology to connect the multiple star topologies together:
Reasons:
This topology is more suitable forØ large networks where ring or star topologies are not suitable to connect the large number of networks.
There are no inflections in either expanding orØ removing the nodes.
Tree topology is more convenient because of itØ sub-parts.
In tree topology there is point to point wiring for individualØ segments.
All the computers have access to the larger and their immediateØ networks.
We can attach more devices and networks to the central hub inØ tree topology because of secondary hub devices.
Q.2 Idea solution:-
A packet and a frame are both packages of data moving through a network.
A packet exists at Layer 3 of the OSI Model, whereas a frame exists at Layer 2 of the OSI Model.
Layer 2 is the Data Link Layer. The best known Data Link Layer protocol is Ethernet.
Layer 3 is the Network Layer. The best know Network Layer protocol is IP (Internet Protocol).
To move through a network, a packet is encapsulated into one or more frames
Packet This term is consided by many to correctly refer to a message sent by protocols operating at the network layer of the OSI Reference Model. So you will commonly see people refer to packets . However, this termin is commonly also used to refer generically to any type of message, as i menitoned earlier.
Frame This term is most commonly associated with messages that travel at low levels of the OSI Reference Model. In particular, it is most commonly seen used in reference to data link layer messages. It is occasionally also used to refer to physical layer messages, when message formatting is performed by a layer 1 technology. A frame gets its name from the fact that it is created by taking higher-level packets or datagrams and "framing" them with additional header information needed at the lower level.
Q.3 solution:-
The numbers of cable links required for mesh topology are:
Number of devices = 11
Number of links = n (n-1)/2
=11 (11-1)/2 = 55
Number of I/o ports = (n-1) = 11-1 = 10
