ROUTER:-
Router is the basic backbone for the Internet. The
main function of the router is to connect two or more than two network and
forwards the packet from one network to another. A router connects multiple
networks.
main function of the router is to connect two or more than two network and
forwards the packet from one network to another. A router connects multiple
networks.
This means that it has multiple interfaces that each belong to a
different IP network. When a router receives an IP packet on one interface, it
determines which interface to use to forward the packet onto its destination.
The interface that the router uses to forward the packet may be the network of
the final destination of the packet (the network with the destination IP
address of this packet), or it may be a network connected to another router
that is used to reach the destination network.
A Router is a computer, just like any other computer
including a PC. Routers have many of the same hardware and software components
that are found in other computers including:
including a PC. Routers have many of the same hardware and software components
that are found in other computers including:
• CPU
• RAM
• ROM
• Operating System
The primary responsibility of a router is to direct
packets destined for local and remote networks by:
packets destined for local and remote networks by:
• Determining the best path to send packets
• Forwarding packets toward their destination
The router uses its routing table to determine the
best path to forward the packet. When the router receives a packet, it examines
its destination IP address and searches for the best match with a network
address in the router’s routing table. The routing table also includes the
interface to be used to forward the packet. Once a match is found, the router
encapsulates the IP packet into the data link frame of the outgoing or exit
interface, and the packet is then forwarded toward its destination.

Router are both types Wireless and Wired. For Example when we are connect our Laptop to internet via WiFi Connection then it is work with a Wireless Router. But When we are connect our Computer with internet via a Ethernet cable then it work with Wired Router.
So, these are the best example of Wireless and Wired Router.
