What is meant by flow control?
Definition. Flow control is a synchronization protocol for transmitting and receiving units of information. It determines the advance of information between a sender and a receiver, enabling and disabling the transmission of information.
What is meant by error control?
Error control is the technique of detecting and correcting blocks of data during communication. If proper error control is in place, transmitted and received data is ensured to be identical, as in many cases communication channels can be highly unreliable.
What is flow control and its types?
Flow control is design issue at Data Link Layer. It is technique that generally observes proper flow of data from sender to receiver. Flow control in Data Link Layer simply restricts and coordinates number of frames or amount of data sender can send just before it waits for an acknowledgment from receiver.
What is the importance of flow control?
Flow control is important because it is possible for a sending computer to transmit information at a faster rate than the destination computer can receive and process it.
Why do we need error control?
With the error control process, we can be confident that the transmitted and received data are identical. Data can be corrupted during transmission. For reliable communication, error must be detected and corrected. Error control is the process of detecting and correcting both the bit level and packet level errors.
Why do we need flow control?
Where does flow and error control take place?
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.
What does flow control mean in a network?
TechTarget Contributor Flow control is the management of data flow between computers or devices or between nodes in a network so that the data can be handled at an efficient pace. Too much data arriving before a device can handle it causes data overflow, meaning the data is either lost or must be retransmitted.
Why is flow control important in data link layer?
The flow control is a design issue at data link layer and transport layer. A sender sends the data frames faster then the receiver can accept. The reason can be that a sender is running on a powerful machine.
What is the difference between feedback based control and flow control?
In feedback-based control whenever the sender sends the data to the receiver, the receiver then sends the information back to the sender and permits the sender to send more data or inform the sender about how the receiver is doing. The protocols of feedback-based control are sliding window protocol, stop-and-wait protocol.
