Explain half-duplex and full-duplex communication?..

Answer / riyaz

Duplex is a method of communication method in which a
system can send and receive data i.e bi-directional
communcation.

Half Duplex is the system in which either data is
transmitted or received (any one process at a time)

Full duplex is the system in which data is transmitted and
received simultaneously

Explain half-duplex and full-duplex communication?..

Answer / syed yakub sha

A duplex communication system is a system composed of two
connected parties or devices that can communicate with one
another in both directions. (The term duplex is not used
when describing communication between more than two parties
or devices.)

Duplex systems are employed in many communications networks,
either to allow for a communication "two-way street" between
two connected parties or to provide a "reverse path" for the
monitoring and remote adjustment of equipment in the field.

A half-duplex system provides for communication in both
directions, but only one direction at a time (not
simultaneously). Typically, once a party begins receiving a
signal, it must wait for the transmitter to stop
transmitting, before replying.

An example of a half-duplex system is a two-party system
such as a "walkie-talkie" style two-way radio, wherein one
must use "Over" or another previously-designated command to
indicate the end of transmission, and ensure that only one
party transmits at a time, because both parties transmit on
the same frequency.

A good analogy for a half-duplex system would be a one-lane
road with traffic controllers at each end. Traffic can flow
in both directions, but only one direction at a time,
regulated by the traffic controllers.

A full-duplex, or sometimes double-duplex system, allows
communication in both directions, and, unlike half-duplex,
allows this to happen simultaneously. Land-line telephone
networks are full-duplex, since they allow both callers to
speak and be heard at the same time. A good analogy for a
full-duplex system would be a two-lane road with one lane
for each direction.

Examples: Telephone, Mobile Phone, etc.

Explain half-duplex and full-duplex communication?..

Answer / abdul quadir khumani

Let, we have two systems A & B

Half Duplex = in this type of communication both can work as
receiver and transmitter. but when A is acting as a
transmitter then B must be working as a receiver.
and when B is acting as a transmitter then A must be working
as a receiver.
Eg. Wireless used by police.


Full Duplex = in this type of communication, A and B can
work as a transmitter and receiver together
Eg. all Telephones and Mobile Phones
