Hi. I am very confused on what is a router. I looked on the internet for the difinition. All I got was:
A device that forwards data packets along networks. A router is connected to at least two networks, commonly two LANs or WANs or a LAN and its ISPís network. Routers are located at gateways, the places where two or more networks connect.
Routers use headers and forwarding tables to determine the best path for forwarding the packets, and they use protocols such as ICMP to communicate with each other and configure the best route between any two hosts.
I got a little more info on it but still a little confused. The reason why I ask is becuase I have this game called "Home World 2" and play on multiplayer mode. When more than 2 players get in the game my ping goes over the limit (gets higher than .500 ping). One of the players asked me if I was behind a router (firewall). Can any1 tell me what s/he meant? Is router the same as a firewall? Also, if there is more to the definition to a router? Thank you for your time.
