A router is a computer that forwards OSI layer 3 packets from interface to interface. It has a table (set of rules) called a routing table that makes it determine what interface it should sent a packet out on. Routers decrement the IP time-to-live on the packet they receive before they pass it on, meaning they have to recompute the checksum on the IP header.
