WebSocket is the protocol that provides full-duplex communication. It enables simultaneous two-way communication between a client and server over a single connection, allowing data to be sent and received in real-time. This is particularly useful for applications that require constant data updates, such as chat applications or live data feeds.
Which protocol provides full-duplex communication HTTP, MQTT, WebSocket and COAP?
Among HTTP, MQTT, WebSocket, and COAP, WebSocket provides full-duplex communication. HTTP and COAP are generally request-response protocols that do not natively support full-duplex communication. MQTT, while supporting bidirectional communication, typically operates in a publish-subscribe model where messages are not continuously open for real-time two-way exchange like WebSocket.
Duplex communication refers to the ability of a communication channel to send and receive data. There are two main types: half-duplex and full-duplex. In half-duplex communication, data transmission occurs in both directions, but not simultaneously; each party must take turns sending and receiving data. In contrast, full-duplex communication allows data to be sent and received simultaneously, enabling more efficient and continuous interaction.
Full-duplex data transmission allows for simultaneous two-way communication. This means that data can flow in both directions at the same time without waiting for one party to finish before the other can start. This is achieved through separate channels or a communication protocol that supports such simultaneous data exchange, enhancing the efficiency and speed of interactions.
