Types of LAN Topology

Types of LAN Topology

1. the type of topology, namely:

• Bus

Bus topology consists than a few computers that are connected to the main cable using a terminator. The cable used is sepaksi cable, (50 ohm coaxial cable) and RG58 connector. The maximum cable distance is 185 meters.
Goodness Bus Topology
Glad to add or subtract computer and nod without interrupting the operation that has been executed.
Less LAN cable and unlimited distance.
Cheap.
Corresponding to a small circuit.
Weakness Bus Topology
If the spinal cord (backbone) or the ubiquitous nodnya problematic circuit can not function.
Require a terminator for both the spinal cord hujung.
Difficult kerosakan impressive.
Need repeater (repeater) if the distance juah LAN.
Perisian is needed to circumvent perlanggaran (collision) of data

• Star

Star topology connects each node (computer and other equipment) to a hub or switch. The data will be delivered piping in star topology via a hub or switch prior to the destinations. Hub also serves oversee and supervise the delivery of data in the series. The cable used is distorted pair cables (unshielded twisted pair) or fiber optic.
Goodness Star Topology
Easy to connect a cable circuit
Easy mengenalpasti problem
There is no interference with the system when connecting circuit or dispose of the equipment in the circuit.
Weakness Star Topology
Require a long cable (one cable each node)
Had the hub fails the entire range of functions can not operate
Kos versus installation over a bus topology.

• Mesh

In a mesh topology each computer is connected directly to another computer (peer to peer). Each computer has its own path to another computer, it will not happen sehigga collision domain.
Weakness mesh topology
and use ethernet cable so that it takes a lot of substantial funds.
The advantages of mesh topology
Advantages of Mesh topology
if there is one track on breaking computer, the computer is still able to relate to other lines.

• Ring

Ring topology connects computers in the form of cable loop. Signal will be sent around in one direction and through each computer. Each computer on the ring topology will also function as repeaters (signal booster) and sends a signal to the computer next to it. Because each signal through each computer, so if one computer is having problems can affect the entire network.
advantages of ring topology that is able to save cable
deficiency ring topology that if one broke the other will be disconnected

• Tree 

The network topology is also called multilevel network topology. This topology is commonly used for interconnection between different central hierarchy. For the lower hierarchy depicted in the lower location and growing up having the higher hierarchy. This type of network topology suitable for use in computer network systems
