A switch sorts and distributes the network packets sent between the devices on a local area network (LAN), while a router is a gateway that connects two or more networks, which can be any combination of LANs, wide area networks (WAN), or the Internet.
Conclusion:
What i have learned, a router uses tables to determine the best path to use to distribute the network packets it receives, and a protocol such as ICMP(Internet Computer Message Protocol) to communicate with other routers. A router is a significantly more complicated device than a switch--essentially a specialized computer--and more advanced models may use a reconfigurable operating system such as Linux, rather than firmware coded directly into the hardware. Both routers and switches operate on layers 2 and 3 of the OSI model. So, For me router is more intelligent than switch.
