 DISCUSSION INFO: Direction of data flow (simplex, half duplex, full duplex), Topology design, categories of network (LAN, MAN, WAN, WLAN), Reference models: OSI reference model, TCP/IP reference model, their comparative study. Network Devices.       Transmission Modes in Computer Networks (Simplex, Half-Duplex and Full-Duplex)   Transmission mode means transferring of data between two devices. It is also known as communication mode. Buses and networks are designed to allow communication to occur between individual devices that are interconnected. There are three types of transmission mode:    These are explained as following below.   1. Simplex Mode: In Simplex mode, the communication is unidirectional, as on a one-way street. Only one of the two devices on a link can transmit, the other can only receive. The simplex mode can use the entire capacity of the channel to send data in one direction. Example: Keyboard and traditional monitors. ...
