Key Differences
Half Duplex Transmission Mode is a communication method where data can be transmitted in both directions, but not simultaneously. In contrast, Full Duplex Transmission Mode allows simultaneous two-way communication, enhancing speed and efficiency.
In Half Duplex Transmission Mode, a device must wait for the other to finish transmitting before it can send data. Full Duplex Transmission Mode, however, enables both devices to send and receive data at the same time without waiting.
Half Duplex Transmission Mode is like a two-way street where only one vehicle can pass at a time, leading to potential delays. Full Duplex Transmission Mode is akin to a dual carriageway, allowing traffic to flow in both directions simultaneously.
Half Duplex systems are simpler and less expensive but less efficient than Full Duplex systems, which require more complex and costly hardware but offer greater efficiency and speed.
In practice, Half Duplex Transmission Mode is suited for environments where simultaneous communication is not critical, whereas Full Duplex is ideal for high-speed, real-time communication needs.
