What is flow control and error control in data link layer briefly describe?
Flow control is meant only for the transmission of data from sender to receiver. Error control is meant for the transmission of error free data from sender to receiver. 2. For Flow control there are two approaches : Feedback-based Flow Control and Rate-based Flow Control.
Which layers provide flow control and error control?
The transport layer provides mechanisms such as error control, flow control, and congestion control to keep track of the data packets, check for errors and duplication, and resend the information that fails delivery.
Are the flow control and error control mechanism handled at the data link layer?
For the node-to-node delivery of the data, the flow and error control are done at the data link layer. Flow Control mainly coordinates with the amount of data that can be sent before receiving an acknowledgment from the receiver and it is one of the major duties of the data link layer.
Why is flow control required at both data link and transport layers?
Flow control in transport layer ensures the delivery of the message globally, as the two points of connection over this protocol are logically connected. Whereas in data-link layer, the concern is to deliver message locally, as the two points of connection over this protocol are physically connected.
Why is flow control required at both the data link and transport layers?
What do you mean by error control?
Error control is the technique of detecting and correcting blocks of data during communication. In other words, it checks the reliability of characters both at the bit level and packet level.
What is error control in transport layer?
TCP provides reliability using error control. Error control includes mechanisms for detecting corrupted segments, lost segments, out-of-order segments, and duplicated segments. Error control also includes a mechanism for correcting errors after they are detected.
