Ring Topology

Network with ring topology is similar to a bus topology, but the edges are interconnected to form a circle.

Ring topology connects the nodes on the network with a circle in a way each node is connected to the next node.

Last node is connected to the first node. Each node checks the data to be transmitted over the network. If the data (called a token) is not addressed in the data node then moves to the next node.

The benefit of using ring topology:

a. Save the cable, to build a network with this topology is less expensive when compared with the star topology.

b. Can avoid collisions of data files that are sent as data flows in one direction so that the data transmitted to the next will be doneafter the first shipment is complete.

c. Easy to build it.

d. All computers on the network have the same status.

Disadvantages of using a ring topology:

a. Sensitive to errors.

b. Network development is more rigid, when the cable disconnected then all the computers can not be used

Tree Topology

Tree topology is a combination of characteristics between the star topology and bus topology. Topology consists of a collection of star topology are connected in a bus topology as the backbone. Computers connected to the hub, while the other hub is connected as the backbone path (backbone) that has a bus topology.

The benefit of using Tree topology:

a. Management control is easier because it is centralized and is divided into tiers levels.

b. Easy to develop

c. Supported by hardware and software from several companies

Disadvantages of using a Tree Topology:

a. If one node is damaged, then the node is located at the bottom level will be damaged.

b. Data files can crash (collision).

c. More difficult to configure and install cable than other topologies

Bus Topology

Bus topology connects computers to each other in chain with the intermediary of a cable which is usually a single type of coaxialcable (coaxial). All Nodes are connected in series using a cable .Bus topology generally do not use an active device to connect computers. Therefore, the ends of coaxial cable should be covered with prisoners in order to avoid reflections that can cause interference that causes network congestion.

The benefit of using a bus topology:

a. Save cables and cheaper, as prices are cheaper cables used and the network hub is not required.

b. Simple wiring layouts

c. If one dies then the computer will not disturb the other computer.

d. Easy to develop.

Disadvantages of using a bus topology, namely:

a. Fault detection and isolation of very small

b. Density of traffic collisions, so often the case file data is sent.

c. When one client is damaged or broken then the cable network is not functioning.

Star Topology

Star topology is a network topology of the most frequently used. In a star topology, centralized control and all links must pass through the center of the channel data to all nodes or computers in their voting. Central node in the call by the primary station or server and the other part is called the secondary station or client. In the star topology, which disrupted the connection between a node and the hub does not affect the network. If the hub disrupted (damaged) then all the nodes which connect to the hub can not communicate with each other can not. A node is a connection or connection point in the network, while the hub serves to receive signals and pass all of the computer connected to the hub.

The benefit of using the star topology:
1. High flexibility.
2. Additions or changes to the computer very easy and does not disturb the other networks, namely by pulling the cable into the hub.
3. Centralized control so easily in network management.
4. Ease of detection and isolation of faulty or damaged, if there is one cable to the node is lost t then it will not affect the overall network. Only a broken cable that can not be used.
5. The number of computer users more than the bus topology

Disadvantages of using a star topology:
1. extravagant cable
2. Need special handling
3. If the Hub Damaged then in the same network hub will be damaged.

The Meaning of Net Topology

Topology is a term used to describe how to connect computers in a network. Physical topology describes the actual layout of the hardware (hardware) network, while the logical topology describes the behavior of computers on the network from the viewpoint of its human operator (brainware). On the subject this time we will explore on Physical Network Topology.
