Kinds of network topology

Kinds of network topology

 1. Star Topology
The star topology or a star topology is often called. In this topology we have to use other tools to help connect computer networks. Examples of tools in use here is the hub, switch, etc.. In the visible image of the hub serves as a hub of computers interconnected.
Pros:• Most flexible• Installation / changing station is very easy and does not interfere with other parts of the network• Centralized Control• Ease of detection and fault isolation / damage• ease of network managementDisadvantages:• Boros cable• Need special handling• Centralized control (HUB) so critical element
 2. Bus Topology
 topology is widely used in the cable uses sepaksi mushroomed. By using T-Connector (with a 50 ohm terminator at the end of the network), then the computer or other network devices can be easily connected to each other.

Excess• Save cables• Layout simple cable• Easy to developShortage• detection and fault isolation is very small• Traffic density• If one client is broken, then the network can not function.• Required repeater for long distance

3. Topology RING
 Token-ring method (often called the ring anyway) is how the computer so that the ring-shaped (circular). Each node has the same degree. The network will be referred to as a loop, the data is sent kesetiap node and any information received nodes examined whether the data address for him or not.
Profit• Save CablesLoss• Be sensitive to errors• Development of a network of more rigid4. Topology tree
Topology also called tree or hierarchical topology and can also be called a multilevel topology is a topology that can be used on the network in a multi-storey office space.
In the picture we can see the relationship between one computer to another computer with a branching hierarchy jelas.sentral center or who are at the very top is an active central central while underneath is a passive central
Pros:

• Can the formation of a group that is required at all times. For example, companies can form a group consisting of terminal bookkeeping, as well as the other groups formed for the sales terminal.Disadvantages:• If the node is higher then not working, then other groups that are below it eventually becomes ineffective. The workings of a tree network is relatively slow.

5. Mesh TopologyTopology netting or mesh topology is a form of relationship between devices where each device is connected directly to other devices on the network. As a result, the mesh topology each device can communicate directly with the target device (dedicated links).
Thus the maximum number of connections between devices on a network bertopologi mesh can be calculated that as many as n (n-1) / 2. In addition, because each device can be connected to other devices on the network, each device must have as many as n-1 Port Input / Output (I / O ports).Pros:

• Relationship dedicated links to ensure the data is sent directly to the destination computer without having to go through other computers so that they can more quickly because of the link is used exclusively for communicating with the destination computer only (not used beramai-ramai/sharing).• Have a Robust properties, ie the event of disruption in the connection of computer A with computer B because of damage to the cable connections (links) between A and B, then the interference will not affect A computer connection with other computers.• Privacy and security in mesh topology more secure, because the communication that occurs between the two computers will not be accessible by other computers.• Facilitate the identification of problems in the event of damage to connections between computers.Disadvantages:

• Requires a lot of cable and port I / O. more and more computers in the mesh topology is needed more and more cable links and port I / O (see calculation formula needs wiring and Port).• It is at once also indicate that the topology of this type * Because each computer must be connected directly to another computer then the installation and configuration becomes more difficult.• The number of wires used also suggests a possible need for space in the room where the computers are located
