In order to fulfil its function to buffer and transfer data packets among networks the router acts as a junction between two or more of those networks.

Due to the fact that the router is different from a switch (that is working on layer 2) and a hub (that is working on layer 1) it is possible that they work for different situations. So a switch may be used in order to connect devices to form a Local area network (short LAN).

In comparison to a switch a router at home is used in order to connect the Internet Service Provider's (short ISP) network together with the LAN in the home and a single broadcast domain.

In general this ISP network is an internet address and the home is usually using a range of different private IP addresses. Even if these two network products are different, it may be possible that they are combined in one single package. As a router routes packets, it communicates with other routers in order to fulfil its function.

To communicate with other routers it uses routing protocols and it also uses this information to create and maintain a routing table. The best routes to certain network destinations as well as the path to the next hop router are stored in those routing tables.

The difference between a hub and a switch is that while a hub forwards every incoming packet out via all ports, a switch forwards each incoming packet only to the port that offers access to the destination system.
A computer network refers to an interconnected group of computers. The networks may be classified according to the network layer at which they function depending upon the basic reference models. The reference models may differ from industry to industry, just like the five-layer Internet Protocol Suite model.
