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 Baseband refers to local area networks, and broadband refers to wide area networks. Broadband and baseband refer to the different frequencies at which infrared operates then transmitting signals in certain conditions 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 Baseband refers to local area networks, and broadband refers to wide area networks.
