The
router has many advantages. First, a router can work on both LAN and WAN,
second, it is able to define the best way the information or data have to
follow; third, a router is able to filter the broadcasts while leading
them between two interfaces. Also, a router can be connected to many media
and architectures and this facilitates the work in some companies.
At the same time a router has some
disadvantages. The most important one is that it costs more than any other
device that can play a similar role like Hub, Bridge, and Switch.
Then, a router functions only according to a routing protocol. Finally,
the more data it has to filter, the slower the router’s function gets.
