Transmission Modes in Computer Networks Transmission mode refers to the mechanism of transferring of data between two devices connected over a network. It is also called  Communication Mode . These modes direct the direction of flow of information. There are three types of transmission modes. They are: 1.     Simplex Mode 2.     Half duplex Mode 3.     Full duplex Mode SIMPLEX Mode In this type of transmission mode, data can be sent only in one direction i.e. communication is unidirectional. We cannot send a message back to the sender. Unidirectional communication is done in Simplex Systems where we just need to send a command/signal, and do not expect any response back. Examples of simplex Mode are loudspeakers, television broadcasting, television and remote, keyboard and monitor etc. HALF DUPLEX Mode Half-duplex data transmission means that data can be transmitted in both directions on a signal carrier, but not at the same time. For example , on

What is Software :  Computer software , or simply software, is a kind of programs that enable a user to perform some specific task or used to operate a  computer . It directs all the peripheral devices on computer system - what to do and how to perform a task. PC Software plays a role of mediator between user and computer hardware. Without Software, a user can’t perform any task in  digital computer . A computer system can be divided into three components: the hardware, the software and the users. Software can be further divide into mainly two parts: Application software and System Software. Bare use of hardware is not easy, so to make it easy software is created. Type of Software Software has mainly divided into two Categories: Application software and System software. Application Software Applications software  also called  end-user programs  or simply an app. It is resides above system software. Applications software is used by end user for specific purpose.  It is
