The fastest communication mode is Full Duplex. In this mode, data can be sent and received at the same time without waiting.

Full Duplex is like a two-way road where both directions can move at once. It improves speed and efficiency compared to other modes.

Other modes:

• Simplex: Data flows in only one direction (e.g., keyboard to computer)


• Half Duplex: Data flows both ways, but one at a time (e.g., walkie-talkie)


• Full Duplex: Data flows both ways at the same time (e.g., phone calls)

Key points:

• Full Duplex allows simultaneous send and receive


• It is faster than Simplex and Half Duplex


• Used in advanced communication systems like telephones and networks

Understanding communication modes helps you learn how devices exchange data and why Full Duplex is the fastest method.
