Router
From The IT Law Wiki
A router is a hardware device or software program that forwards Internet and network traffic between computer networks. A router stores each packet and reads its IP destination address. Using a routing table, it finds the best path for forwarding ("routing") a packet to the next router on the network until all of the packets are received at the destination computer, where all of the packets in a message are reassembled.
A router typically uses a simple set of rules, known as an access control list (ACL), that addresses only the most basic characteristics of network traffic.
