Duplex transmission is a type of communication used in cables that enable the transmission of data in both directions, either one direction at a time or both directions simultaneously. Half-duplex transmission is used when only one direction of communication is active at a time, while full-duplex transmission is used when both directions of communication are active simultaneously.
Half-duplex transmission is typically used in older technologies, such as RS-232 serial cables. Full-duplex transmission is typically used in modern technologies, such as Ethernet cables. In full-duplex transmission, data can move in both directions at the same time, allowing for more efficient communication and faster data transfer.
In both half-duplex and full-duplex transmission, the data is transmitted through a cable, which is typically a copper wire but can also be a fiber-optic or coaxial cable. The cable is used to connect two devices, such as a computer and a router, and the data is transmitted between the two devices in either direction. The data is sent in packets, which contain the data, along with any instructions needed for the receiving device to interpret the data.
The data is transmitted over a cable in either an analog or digital format. In an analog format, the data is transmitted as a continuous signal, while in a digital format, the data is transmitted as binary codes. In both formats, the data is sent in a series of pulses, which can be interpreted by the receiving device.
Duplex transmission is a widely used method of communication that enables efficient data transfer between two devices. It is used in a variety of applications, from networking to broadcasting, and is used to send data in both directions, either one direction at a time or both directions simultaneously.
