Computer Networking The research and development department at your office has been experimenting with different technologies to help improve the performance of the network. One group has been examining the use of a broadband network versus a based band network. Select the correct statement about broadband and baseband. Broadband networks carry several channels on a single cable, whereas in a baseband network several cables carry one channel Broadband and baseband refer to the different frequencies at which infrared operates then transmitting signals in certain conditions Baseband refers to local area networks, and broadband refers to wide area networks. Baseband operates at a standard bit rate, whereas broadband may operate at different rates as needed Baseband networks carry a single channel on a single cable, whereas broadband networks carry several channels on a single cable Broadband networks carry several channels on a single cable, whereas in a baseband network several cables carry one channel Broadband and baseband refer to the different frequencies at which infrared operates then transmitting signals in certain conditions Baseband refers to local area networks, and broadband refers to wide area networks.

Computer Networking Which of the following is true when describing a multicast address? Packets addressed to a unicast address are delivered to a single interface. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap. Packets are delivered to all interfaces identified by the address. This is also called a one-to-many address. Identifies multiple interfaces and is only delivered to one address. This address can also be called one-to-one-of-many. Packets addressed to a unicast address are delivered to a single interface.
