Here is the difference between simplex half duplex and full duplex communications data transmission modes in a computer networking.
Simplex
In the simplex mode, the communication is unidirectional. Only one device can transmit the data whereas another device can only receive the data. For example, the communication between the keyboard and CPU follows a simplex transmission mode. In this mode, the keyboard can only send data and the CPU can only receive data.
Half Duplex
In half-duplex transmission, both the devices can transmit and receive data but not simultaneously. When one device is transmitting, the other device can only receive. An example is a walkie-talkie.
Full Duplex
In the full-duplex mode, both the connected devices can send as well as receive data at the same time. An example is a telephone.
During communication through telephone, mobile, both the person can talk at the same time i.e. (sending and receiving data)
