1. Data Transmission Mode
Data transmission mode
is the way of transmission of data from one location to another. There are
three types of transmission mode:
i) Simplex mode ii) Half duplex mode iii) Full Duplex Mode
i) Simplex mode ii) Half duplex mode iii) Full Duplex Mode

Simplex mode
The transmission mode in which transmission of data can take place in one direction only is called simplex mode.
E.g.: Newspaper, Radio and Television.
The transmission mode in which transmission of data can take place in one direction only is called simplex mode.
E.g.: Newspaper, Radio and Television.
3.
Half duplex mode
The transmission mode in which transmission of data can take place in both directions but only in one direction at a time is called half duplex mode. E.g.: Wireless handset and walkie-talkie.
The transmission mode in which transmission of data can take place in both directions but only in one direction at a time is called half duplex mode. E.g.: Wireless handset and walkie-talkie.
4.
Full duplex mode
The transmission mode in which data can be transmitted in both directions simultaneously is called full duplex mode. E.g.: Telephone, internet etc.
The transmission mode in which data can be transmitted in both directions simultaneously is called full duplex mode. E.g.: Telephone, internet etc.

Bandwidth
Bandwidth can be defined as the maximum volume of data that can be transmitted through a communication system. We can measure bandwidth in digital devices by bits per second and in analogue devices by cycles per second or Hertz (Hz).
