Routers perform the decision process that selects what path a packet takes. These （） laye

r devices participate it the collection and distribution of network-layer information, and perform Layer 3 switching based on the contents of the network layer （） of each packet. You can connect the routers directly by point-to-point （） or local-area networks, or you can connect them by LAN or WAN switches. These Layer 2 switches unfortunately do not have the capability to hold Layer 3 （） information or to select the path taken by a packet through analysis of its Layer 3 destination address. Thus, Layer 2 switches be involved in the Layer 3 packet （） decision process.

A.application B. network C.physical D.link A.header B.connection C.protocol D.data A.medium B.links C.switches D.carriers A.network B.links C.protocol D.routing A.switching B.processing C.forwarding D.connecting

TCP functions at the Open System Interconnection(OSI)(61)layer, or Layer 4. Its chief responsibility is to ensure(62)end-to-end connectivity. IP, located one layer down, at the OSI network layer, or Layer 3, communicates the addresses of each(63)sender and receiver to the routers along the way. Routers and Layer 3 switches can read IP and other Layer 3(64). This information, combined with routing tables and other network intelligence, is all it takes to get(65)the room or around the world via TCP/IP.
