Baseband and broadband are two techniques used to transmit data packets over cable.
Bandwidth is the maximum speed at which a particular communications medium, such as cables, can transfer information. Bandwidth measurement depends on the type of signal (analog or digital) and the media used to carry the information.
Type of Signal (analog or digital) + Type of Media = Bandwidth
In an analog signal, information travels as a continuously changing wave. This signal cycles up and down in a wavelike pattern. analog A signal that travels as a continuously variable wavelike pattern.
Broadband transmissions can be divided into multiple channels separated by small bands of unused frequencies to avoid one channel interfering with the signal being transmitted on its neighbors.
Broadband is unidirectional—it moves in one direction only. To send and receive, the communications bandwidth is divided into two channels, one for each direction. broadband transmission Transmissions that rely on an analog signal, a range of frequencies, and a communications medium. Broadband signals can be divided into multiple channels separated by small bands of unused frequencies to avoid interference.
Baseband transmissions send digital signals over a single channel. Multiple transmissions can be sent through the channel simultaneously through a technique known as multiplexing.
baseband transmission Transmissions of digital signals over a single channel, typical of most current LANs. One signal at a time travels over the network cable.
multiplexing Multiple transmissions sent through a channel simultaneously and are interwoven into a single signal. Network models describe how different network devices communicate with each other. The OSI model consists of seven layers that describe the tasks a network component must handle.
