How is full duplex implemented?

Full duplex communication is implemented by allowing simultaneous transmission and reception of data between two devices. This is typically achieved using separate channels for sending and receiving signals, such as in telephone systems where one channel is dedicated to outgoing audio and another to incoming audio. In networking, full duplex is implemented through technologies like Ethernet, which can use twisted pairs of wires to enable concurrent data flow in both directions. This setup enhances the overall efficiency and speed of communication compared to half duplex systems, where data transmission occurs in only one direction at a time.
