Answer: D - Broadband divides communication channels into individual and independent channels so different types of data can be transmitted simultaneously. Baseband permits only one signal to be transmitted at a time, whereas broadband carries several signals over different channels. Broadband encompasses many different technologies, but one general rule is that it provides data transmission higher than 56 Kbps, which is what a standard modem dial-up connection line provides. Broadband communications provide channels for data transmission and can be used by many users.
