The document explains the three types of transmission modes in computer networks: simplex, half-duplex, and full-duplex. Simplex is uni-directional, half-duplex allows two-way communication but not simultaneously, and full-duplex supports simultaneous two-way communication. It also compares the performance of each mode, indicating that full-duplex offers the best performance, followed by half-duplex and then simplex.

Transmission Modes in Computer Networks
Transmission mode means transferring of data between two devices.
It is also known as communication mode
There are three types of transmission mode:-
•Simplex Mode
•Half-Duplex Mode
•Full-Duplex Mode

SIMPLEX HALF DUPLEX FULL DUPLEX
Simplex mode is a
uni-directional
communication.
Half duplex mode is
a two-way
directional
communication but
one at a time.
Full duplex mode is
a two-way
directional
communication
simultaneously.
In simplex mode,
Sender can send
the data but that
sender can’t receive
the data.
In half duplex mode,
Sender can send
the data and also
can receive the data
but one at a time.
In full duplex mode,
Sender can send
the data and also
can receive the data
simultaneously.
The simplex mode
provides less
performance than
half duplex and full
duplex.
The half duplex
mode provides less
performance than
full duplex.
Full duplex provides
better performance
than simplex and
half duplex mode.
Example of simplex
mode are:Keyboard
and monitor.
Example of half
duplex mode is:
Walkie-Talkies.
Example of half
duplex mode is:
Telephone.
Difference between Simplex, Half duplex and Full Duplex Transmission Modes:
