What type of connection allows both devices to send and receive data simultaneously?

Full-duplex connections are designed to allow both devices to send and receive data simultaneously. This means that at any given moment, data can flow in both directions, enabling more efficient communication. This is particularly beneficial in network communications where quick exchanges of information are essential, such as in voice over IP (VoIP) calls or real-time video conferencing.

In contrast, half-duplex connections permit data transmission in only one direction at a time, which can lead to delays as devices take turns to send and receive data. Simplex connections are unidirectional and only allow data to flow in one direction, meaning that one device can transmit data while the other can only receive it without the ability to reply. Multi-point connections refer to configurations where multiple devices can communicate with each other but do not inherently indicate simultaneous data transmission capabilities between two specific devices. Therefore, full-duplex is the most efficient and effective option for facilitating simultaneous communication between devices.
