Star Topology Network Definition

Star Topology Network Definition - Star topology used in dense tissue, when the endpoint can be reached directly from the central location, the need for network expansion, and require high reliability.

This topology is an arrangement which uses more cable than the bus and because of all the computers and devices connected to the central point. So if there is one computer or device is damaged then it will not affect the other (networking).

The working principle STAR Network
Each computer in a star topology network to communicate with a central hub that sends back a message to all the computers (in a broadcast star topology network) or only to the destination computer (the star topology switched network). Hub in broadcast star topology network can be active or passive.

Active hub renew received electrical signal and sends it to all computers connected to the hub. Hub type is often referred to as a multipart repeater. If we use the hub have 32 ports, with the entire port filled, then a collision will often occur that will result in decreased network performance.

To avoid this we can use a switch that has the ability to determine the destination path data. Active hubs and switches require electricity to run.

Passives hubs, such as wiring panels or punch-down blocks, only serves as the connection point (connection point) and does not perform signal amplification or signal renew. Passive hubs do not require electrical power to run it.

Star Topology Network Hybrid (HYBRID NETWORK STAR)
We can use some type of cable to implement a network star topology. Hybrid hubs can be used to accommodate several types of cable in a star network.

The star topology is a form of network topologies in the form of convergence of the central node to every node or user. A star network topology including network topology with intermediate costs.

Star topology called because of its shape like a star, a device called a concentrator may be a hub or switch into the center, where all the computers in a network connected to this concentrator. read - what is the internet

Star Topology Sadvantages:
Because each component is connected directly to the central node then management becomes easy
Communication failure easily traced.
Failure of one component / terminal does not affect other communication terminal.
Centralized control to facilitate the detection and isolation of faults and easy network management.

Star Topology Disadvantages:
Failure of the control center (central node) sever all communication
When used as the control center is HUB then the speed will be reduced in accordance with the addition of a computer, the more the slower.
Wasteful in the use of cables
HUB conditions should remain in good condition, HUB damage resulting paralysis of the entire link in the network so that the computer can not communicate with each other.

ConclusionStar topology used in dense tissue,
When the endpoint can be reached directly from the central location, the need for network expansion, and require high reliability. This topology is an arrangement which uses more cable than the bus and because of all the computers and devices connected to the central point.

So if there is one computer or device is damaged then it will not affect the other (networking).
