Correct Answer: TCP-Transmission Control Protocol UDP- user Datagram protocol UDP is user assisted program and converts the application into the encapsulated form and makes it end point for data to send and then TCP helps in transmission or broadcast!

Correct Answer: To send data/info to group of computers using same network

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
