A router is a hardware / device that receives incoming data packets, partially analyzes them and forwards them to another network!
Routes = forwarded! The best-known routers in the private sector are Speedport and the AVM FritzBox. A router has much more functions than other network devices, such as a simple hub, or a so-called switch, which can only perform basic network functions.
For example, a hub is often used to transfer data between computers or network devices, but does not analyze and do nothing with the transferred data. In contrast, routers can analyze the data sent over a network, change how it is packed, and send it to another network or to another network. For example, routers are often used in home networks to share a single Internet connection between multiple computers.
