**Hi steemit friend**
this time I will continue my post about the network topology, I have in the previous post about ring topology, this time I will discuss about topology **star**.

**Star topology** is a form of network topology in the form of convergence from the middle node to each node or user. Each workstation is connected directly to Server or Hub / Swich. Essentially this topology uses Hub / Switch to connect from one computer to another computer. Hub / Switch function to receive signals from kopmputer and forwarded to all computers connected to the Hub / Swich. Star network topology includes network topology with medium cost.

### Advantages
* Damage to one channel will only affect the network  the channel and the linked station.
* The security level is high.
* Resistant to busy network traffic.
* Station addition and subtraction can be done easily.
* Centralized Control Access.
* Ease of detection and fault isolation / damage to network management.
* Paling fleksibel.

### Deficiency
* If the middle node is damaged, then the whole circuit will stop.
* Wasteful in the use of cable.
* HUB / SWITCH becomes a critical element because of centralized control.
* The role of the hub is very sensitive so that when there is a problem with the hub then the network will be down.
* Network depends on the central terminal.
* If using HUB and heavy data traffic can cause slow network.
* Network cost is more expensive than bus or ring.<hr>

In conclusion that with the existence of separate cables for each workstation to the server, the Bandwidth or the width of the communication lines in the cable will be wider so that it will increase or improve the overall network work. And also if there is interference in a cable path then the interference occurs only in communication between the workstation concerned with the server, and the network as a whole does not experience interference.

Need more cable compared to other topology. Because each workstation must have its own cable to connect with Hub / Switch and also require special handling.

** *just so much for my exposure to the topolog star, and maybe I will discuss it on other occasions about other topology networks.* **
