Which of the following does not allow multiple users or devices to share one communications line?
Which of the following does not allow multiple users or devices to share one communications line?
The correct option is A Doubleplexer
Doubleplexer does not allow multiple users or
devices to share one communications line.
A diplexer is a passive device that implements
frequency-domain multiplexing. Two ports (e.g., L and H) are multiplexed onto a
third port (e.g., S). The signals on ports L and H occupy disjoint frequency
bands. Consequently, the signals on L and H can coexist on port S without
interfering with each other.
The best example of a communication device is a
computer Modem, which is capable of sending and receiving a signal to allow
computers to talk to other computers over the telephone. Other examples of
communication devices include a network interface card (NIC), Wi-Fi devices,
and an access point.
Modem (from modulator-demodulator) is a device that
turns the digital 1s and 0s of a personal computer into sounds that can be
transmitted over the telephone lines of Plain Old Telephone Systems (POTS), and
once received on the other side, converts those sounds back into a form used by
a USB, Ethernet, serial,
