Which technology allows for simultaneous two-way communication?

Full Duplex technology allows for simultaneous two-way communication, enabling both parties to send and receive messages at the same time without interference. This capability is particularly beneficial in various communication systems, such as telephony, networking, and data transfer, where real-time interaction is essential.

In contrast, half duplex communication allows for two-way communication, but not simultaneously; instead, one party must wait for the other to finish transmitting before responding. Simplex communication is unidirectional, meaning information can flow in only one direction — one party can send data while the other can only receive it. Single Point Communication is not a standard term typically used in networking or communication technologies, leading to ambiguity about its meaning. Therefore, full duplex is the correct choice as it strictly defines the ability for ongoing back-and-forth communication at the same time.
