Concept Questions on pages 4-5 1. What is the most important function of a router? To route packets to and from networks and computers. 2. Define default gateway: When a computer needs to send a packet to another subnet, it sends the packet to its default gateway, which is also known as the default router. 3. In three of four sentences, explain the purpose of DCE and DTE in WAN links: DCE and DTE are on the circuit ends of leased lines of Telco. DCEs is normally a CSU/DSU that receives information and sets the clocking speed to the DTE. The DTEs are normally routers that send information through the WAN at the rate set by the DCE. 4. Explain what a router is and what it does: A router is a network device, typically connected to a variety of LAN and WAN interfaces, that forwards packets based on their destination IP addresses.
