ROUTER

Router tool is a computer network that sends packets of data through a network or the Internet to its destination, through a process known as routing

Router function:
LAN network connects to the Internet in merutekan tranmisi between the two. ROUTER menstranmisikan information from one network to another network system that works similar to BRIDGE.

In general, the router is divided into two types, namely:

* Static router (the router static) is a router that has a static routing table is set manually by the network administrator.
* Wasted the router (the router dynamic) is a router that has a dab create dynamic routing table, listening to the traffic network with each other and also connected with other routers.


The difference between static and dinamic:

Static routing is configured manually. Routing table is set manually and stored in the router. No information sharing among the router. This resulted in the clear limitations because he can not automatically determine the best route; he always use the same routes that are likely not the best route. If the route change, static router must be updated manually. Because the static router provides full control on the routing table, it is more secure than the dynamic router.

Dynamic routing is able to create their own routing table to talk with fellow router. To do so, he found an alternative route and the route that are on the network. Dynamic router can make a decision on which route a packet reaches the destination. Generally, he sends the package to the most efficient route; the one that produces fewer number of hop. However, if the jammed route, dynamic route can send packages to the alternative route.
