TRANSMISSION MODES IN COMPUTER NETWORK
Transmission mode in computer network refers to the method used to transfer data between devices on a network. There are two main types of transmission modes:
• Simplex mode:
In simplex mode, data is transmitted in only one direction, from the sender to the receiver. This mode is used for one-way communication, such as in radio or television broadcasting.
• Duplex mode:
In duplex mode, data is transmitted in both directions, from the sender to the receiver and from the receiver to the sender. This mode is used for two-way communication, such as in telephone and computer networks.

There are two types of duplex modes:
• Half-duplex mode:
In half-duplex mode, data can be transmitted in both directions, but not at the same time. This means that the sender and receiver take turns transmitting and receiving data.
• Full-duplex mode:
In full-duplex mode, data can be transmitted in both directions at the same time. This means that the sender and receiver can transmit and receive data simultaneously.
Simplex mode in computer network
Simplex mode is a type of data transmission in which data is transmitted in only one direction, from the sender to the receiver. It is commonly used in one-way communication systems such as radio and television broadcasting.
Advantages of Simplex mode:
• Simple: Simplex mode is simple to implement and does not require complex protocols or additional devices.
• Low cost: Since simplex mode does not require additional devices or complex protocols, it is relatively low-cost to implement.
• High-speed: Simplex mode can transmit data at high speeds, making it suitable for applications that require high-speed data transfer.
• Unidirectional: Simplex mode transmits data in one direction, which makes it easy to control the flow of data.
Disadvantages of Simplex mode:
• One-way communication: Simplex mode only allows data to be transmitted in one direction, which makes it unsuitable for applications that require two-way communication.
• No feedback: Since data is transmitted in only one direction, there is no feedback mechanism to confirm that the data has been received, which can lead to errors.
• Limited applications: Simplex mode is mainly used in one-way communication systems such as radio and television broadcasting, which limits its applications.
• No error detection: Since data is transmitted in only one direction, it is not possible to detect errors in the transmitted data.
Half-duplex mode in computer network
Half-duplex mode is a type of duplex mode in computer networks where data can be transmitted in both directions, but not at the same time. This means that the sender and receiver take turns transmitting and receiving data.
Advantages of Half-Duplex mode:
• Simple: Half-duplex mode is relatively simple to implement, as it only requires one channel for communication.
• Cost-effective: Half-duplex mode is less expensive than full-duplex mode, as it requires fewer resources and less expensive equipment.
• Low error rate: The error rate is low in half-duplex mode because data is transmitted in one direction at a time.
Disadvantages of Half-Duplex mode:
• Slow data transfer rate: The data transfer rate is slower in half-duplex mode because the sender and receiver must take turns transmitting and receiving data.
• Limited bandwidth: The bandwidth is limited in half-duplex mode because data can only be transmitted in one direction at a time.
• No simultaneous communication: Simultaneous communication is not possible in half-duplex mode, which can be a drawback in some situations.
Full-duplex mode in computer network
Full duplex mode is a type of data transmission in which data can be sent and received simultaneously by the sender and receiver. In other words, both the sender and the receiver can transmit and receive data at the same time.
Advantages of full-duplex mode:
• Increased data transfer rate: Full duplex mode allows for faster data transfer as both the sender and receiver can transmit and receive data at the same time.
• Improved communication: Full duplex mode allows for more efficient communication between devices on the network, as they can send and receive messages simultaneously.
• More reliable communication: Full duplex mode provides more reliable communication between devices on the network, as it eliminates the need for the sender and receiver to take turns transmitting and receiving data.
• Better utilization of the bandwidth: Full duplex mode allows for better utilization of the available bandwidth on the network, as both the sender and receiver can transmit and receive data simultaneously.
Disadvantages of full-duplex mode:
• High cost: Full duplex mode requires specialized hardware and software, which can be more expensive than half-duplex mode.
• Complexity: Full duplex mode can be more complex to set up and maintain than half-duplex mode.
• Collision: Full duplex mode is more susceptible to collisions if the network is not well managed, as both sender and receiver can send data at the same time.
