Full duplex is a type of data transmission that allows for simultaneous two-way communication over a single cable. In a full duplex system, both the transmitter and receiver can send and receive data at the same time. This means that data can travel in both directions over a single cable at the same time. This is in contrast to half-duplex systems, which can only send data in one direction at any given time.
Full duplex systems are typically used in local area networks (LANs) where communication is needed in both directions between two nodes. They are also used in larger networks, such as those used to provide internet access.
In a full duplex system, each device is connected to the cable using two pairs of wires, one for sending data and one for receiving data. This allows the two devices to communicate simultaneously, without having to stop and wait for the other side to finish transmitting before they can start. This type of system is more efficient because it eliminates the need for the two sides to take turns sending and receiving data.
Full duplex systems also require more bandwidth than half-duplex systems, as each device needs to be able to receive and transmit data at the same time. It is also more expensive than half-duplex systems, as it requires more wires and more complex equipment. However, the increased efficiency and faster speeds that come with full duplex systems make them a popular choice in many applications.
Overall, full duplex systems are a popular choice for many types of networks due to their increased efficiency and faster speeds. They are used in many applications, from local area networks to larger networks that provide internet access. The increased cost and bandwidth requirements of these systems must be taken into consideration when deciding which type of system to use.
