Advantages of using star topology

Answer 1

Advantages:* Good performance

* Reliable (if one connection fails, it doesn't affect others)

* Easy to replace, install or remove hosts or other devices

Disadvantages:* Expensive to install

* Extra hardware required

Answer 2

A star topology has many advantages. Some of the advantages of a properly functioning star topology are listed below;

• The star topology is easy to install and wire.
• The star topology gives a better performance than any other network topology as there is no clogging of nodes. In order to communicate between any two devices only 2 links and 3 devices are involved to prevent confusion. The hub also has adequate capacity to handle high utilization by one device, without disrupting the functioning of the other devices.
• The working of the star topology is simple to establish, understand and navigate. Any fault in the devices connected to the central hub can be detected easily as the malfunctioned device or link is isolated, which allows easy probing into the matter.
• The faulty and defective parts of the network can be easily replaced. Till the links are replaced, the other devices continue their normal functions without any disruptions.

Answer 3

The star topology can add clients fairly easily as long as there are ports or connections through the central device or central building (in case of a star WAN).

Since the single point of failure is the central device and that device rarely will fail, the network is not disturbed with a connection failure of a client.
star topology has many advantages basically in companies and education systems because it has one server and many clients which can easyly opporates in many sourses

Answer 4

In Ring Topology, all the nodes are connected to each-other in such a way that they make a closed loop. Each workstation is connected to two other components on either side, and it communicates with these two adjacent neighbors. Data travels around the network, in one direction. Sending and receiving of data takes place by the help of TOKEN.

Token Passing (in brief) : Token contains a piece of information which along with data is sent by the source computer. This token then passes to next node, which checks if the signal is intended to it. If yes, it receives it and passes the empty to into the network, otherwise passes token along with the data to next node. This process continues until the signal reaches its intended destination.

The nodes with token are the ones only allowed to send data. Other nodes have to wait for an empty token to reach them. This network is usually found in offices, schools and small buildings.

Ring Topology & token

Advantages of Ring Topology

1) This type of network topology is very organized. Each node gets to send the data when it receives an empty token. This helps to reduces chances of collision. Also in ring topology all the traffic flows in only one direction at very high speed.

2) Even when the load on the network increases, its performance is better than that of Bus topology.

3) There is no need for network server to control the connectivity between workstations.

4)Additional components do not affect the performance of network.

5) Each computer has equal access to resources.

Disadvantages of Ring Topology

1) Each packet of data must pass through all the computers between source and destination. This makes it slower than Star topology.

2) If one workstation or port goes down, the entire network gets affected.

3)Network is highly dependent on the wire which connects different components.

4) MAU's and network cards are expensive as compared to Ethernet cards and hubs.

Answer 5

The availability to provide robust communication/connection. This allows a system to access or provide data from two paths in case you path is to fail.

Answer 6

it has bigger communication area than star topology. but expensive than star topology.

think got it.

Answer 7

Start topology does not require as much cable as for instance MASH type. Also if one cable goes down the other part of network still can function (which is not true for ring type).

Answer 8

simple to configure and less expensive to set up and maintain than a server-based network and used for simple tasks.
