CAN is half-duplex. One differential pair means one message at a time.

In full duplex, a device can send and receive data at the same time. In half duplex, it can only communicate one way at a time.

Full Duplex

duplex means one way communication and i think half duplex at different time communication and full duplex means in a same time send and recieve -------------------------------------------------------------- A: Half duplex means a host cannot simultaneously send or receive data. Full duplex means a host can send and receive data simultaneously.

A simple duplex is a channel through which data is transmitted and it can either be half or full duplex. Half duplex means that data can be sent or received but not at the same time while full duplex means that this can happen simultaneously.
