Question: use a telecommunication channel.
Answers
Answer:
1) In telecommunications in general, a channel is a separate path through which signals can flow.
2) In the public switched telephone network (PSTN), a channel is one of multiple transmission paths within a single link between network points. For example, the commonly used (in North America) T-carrier system line service provides 24 64 Kbps channels for digital data transmission.
3) In radio and television, a channel is a separate incoming signal or program source that a user can select.
4) In optical fiber transmission using dense wavelength-division multiplexing (DWDM), a channel is a separate wavelength of light within a combined, multiplexed light stream.
5) On the World Wide Web, a channel is a preselected Web site that can automatically send updated information for immediate display or viewing on request. See push technology.
