FAQs on Flow Control - Fundamentals & Link Layer Video Lecture - Computer Networks - Computer Science Engineering (CSE)

1. What is flow control in computer networks?
Ans. Flow control in computer networks refers to the techniques and mechanisms used to ensure that data transmission between two devices happens at an appropriate rate. It helps in managing the flow of data to prevent congestion and ensure efficient communication.
2. What are the different types of flow control techniques?
Ans. There are several flow control techniques used in computer networks, including: - Stop-and-Wait: The sender waits for an acknowledgment before sending the next data frame. - Sliding Window: Allows the sender to transmit multiple frames without waiting for individual acknowledgments. - Rate-based flow control: Controls the flow of data based on the rate at which the receiver can process it. - Buffering: Involves using buffers to temporarily store data when the receiver is not ready to receive it.
3. What is the purpose of flow control in the link layer?
Ans. In the link layer, flow control ensures that the data transmission between two directly connected devices, such as switches or Ethernet interfaces, happens at an appropriate rate. It prevents overflow or underflow in the receiving buffer and helps in managing the flow of data to maintain efficient communication.
4. How does flow control prevent congestion in computer networks?
Ans. Flow control prevents congestion by regulating the rate at which data is transmitted. It ensures that the sender does not overwhelm the receiver with data faster than it can process. By maintaining a balance between the sender and receiver's data rates, flow control prevents the occurrence of congestion, which can lead to packet loss, delays, and reduced network performance.
5. What is the role of flow control in ensuring reliable data transmission?
Ans. Flow control plays a crucial role in ensuring reliable data transmission by preventing the loss or corruption of data. It ensures that the sender adjusts its transmission rate based on the receiver's ability to handle the data. By avoiding data overflow or underflow, flow control helps in maintaining the integrity of the transmitted data and minimizing the chances of errors or data loss during the communication process.
