Transmission Modes

What is Transmission Modes?
The term Transmission Mode defines the direction of the flow of information between two communication devices i.e. it tells the direction of signal flow between the two devices.
There are three types of transmission modes Simplex, Half duplex (HDX), Full duplex (FOX)

Types of Computer Networks

  • 1. Simplex mode
  • 2. Half-Duplex Mode
  • 3. Full-Duplex Mode
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. The keyboard can only introduce input, the monitor can only give the output.
Half-Duplex Mode: 
In half-duplex mode, each station can both transmit and receive, but not at the same time. When one device is sending, the other can only receive, and vice versa. The half-duplex mode is used in cases where there is no need for communication in both directions at the same time. The entire capacity of the channel can be utilized for each direction.
Example: Walkie-talkie in which message is sent one at a time and messages are sent in both directions.
Full-Duplex Mode: 
In full-duplex mode, both stations can transmit and receive simultaneously. In full_duplex mode, signals going in one direction share the capacity of the link with signals going in another direction, this sharing can occur in two ways:
* Either the link must contain two physically separate transmission paths, one for sending and the other for receiving.
* Or the capacity is divided between signals traveling in both directions.
Full-duplex mode is used when communication in both directions is required all the time. The capacity of the channel, however, must be divided between the two directions.
Example: Telephone Network in which there is communication between two persons by a telephone line, through which both can talk and listen at the same time.

 ### Network Layer: Design Issues and Key Concepts **Network Layer** is responsible for data transfer between devices on different networks. It determines how data is routed from the source to the destination, ensuring it follows the best path. ### 1. **Design Issues in the Network Layer:**    - **Routing**: Deciding the best path for data to travel across the network.    - **Congestion Control**: Preventing network overload, ensuring smooth data flow.    - **Packet Forwarding**: Moving data packets from one network to another.    - **Error Handling**: Detecting and correcting errors that occur during data transmission. ### 2. **Routing Algorithms**: A Detailed Explanation Routing algorithms are methods used by network devices (like routers) to determine the best path for data to travel from its source to its destination. The goal of these algorithms is to ensure that data packets reach their destination efficiently, quickly, and with minimal...
