Correct Answer: One of the main causes of congestion is that traffic is often busy If hosts could be made to transmit at a uniform rate, congestion would be less common Another open loop method to help manage congestion is forcing the packet to be transmitted at a more predictable rate This is called traffic shaping

Correct Answer: Server-based network: Provide centralized control of network resources and rely on server computers to provide security and network administration peer-to-peer network: computers can act as both servers sharing resources and as clients using the resources

Correct Answer: The address resolution protocol(ARP) is used to associate the 32 bit IP address with the 48 bit physical address, used by a host or a router to find the physical address of another host on its network by sending a ARP query packet that includes the IP address of the receiver The reverse address resolution protocol (RARP) allows a host to discover its Internet address when it knows only its physical address

Correct Answer: FDM is an analog technique that can be applied when the bandwidth of a link is greater than the combined bandwidths of the signals to be transmitted

Correct Answer: WDM is conceptually the same as FDM, except that the multiplexing and demultiplexing involve light signals transmitted through fiber optics channel
