What is the difference between flow control and error control

If the sender receives a negative acknowledgement, it should retransmit error frame and all succeeding frames. It sends a negative acknowledgement from only the frame which is lost or damaged. The sender can only send the frame for which the NACK is received. Those are the common error control techniques. Data is transmitted from the sender to receiver.

For reliable and efficient communication, it is essential to use techniques. Flow Control and Error Control are two of them. This article discussed the difference between Flow Control and Error Control.

The difference between the Flow Control and Error Control is that Flow Control is to maintain the proper flow of data from the sender to the receiver while Error Control is to find out whether the data delivered to the receiver is error free and reliable.

Flow control is the mechanism for maintaining the proper transmission from the sender to the receiver in data communication. In case the buffer begins to fillup then the receiver must be able to tell the sender to halt the transmission until once again the receiver become able to receive.

Thus the flow control makes the sender; wait for the acknowledgment from the receiver before the continuation to send more data to the receiver. Error Control contains both error detection and error correction.

It mainly allows the receiver to inform the sender about any damaged or lost frames during the transmission and then it coordinates with the retransmission of those frames by the sender. The term Error control in the data link layer mainly refers to the methods of error detection and retransmission. Error control is mainly implemented in a simple way and that is whenever there is an error detected during the exchange, then specified frames are retransmitted and this process is also referred to as Automatic Repeat request ARQ.

The implementation of protocols is mainly implemented in the software by using one of the common programming languages. The classification of the protocols can be mainly done on the basis of where they are being used. Protocols can be used for noiseless channels that is error-free and also used for noisy channels that is error-creating.

The protocols used for noiseless channels mainly cannot be used in real-life and are mainly used to serve as the basis for the protocols used for noisy channels.

And the error correction that becomes the discovery of blunders and recreation of the first blunder free information. The general thought for accomplishing error detection and adjustment is to add some access to a message, which beneficiaries can use to check the consistency of the conveyed message and to recoup information that has been resolved to be undermined.

Error discovery and amendment plans can be either orderly or non-precise: In a deliberate plan, the transmitter sends the first information and connects a settled number of check bits which come from the data bits by some deterministic calculation. Two types of error control exist, the first one called the forward error control adds the information before it gets transmitted and becomes useful data.

The feedback error control helps in rechecking the information once it reaches the feed. These techniques become useful only when we know what type of error exists.

Then the recipient sends the acknowledgment.

If the sender has not received an acknowledgment within a specified time, it will send this frame again. This period is determined using a special device called a timer. When the frame is sent, the sender starts the stopwatch. He has a fixed time. If there is no recognizable acknowledgment of receipt from the recipient, the sender will retransmit this frame again.

If there is no error, the recipient sends the acknowledgment as usual. If the destination detects an error, it sends a negative acknowledgment NACK for this frame. The receiver will discard the error frame and all future frames until the error frame is corrected. If the sender receives a negative acknowledgment, it should retransmit the error frame and all subsequent frames.

It sends a negative acknowledgment from the only lost or damaged frame. The sender can only send the frame for which the NACK is received. These are the common error checking techniques. Similarity between flow control and error control? Flow control and error control occur in the data link layer. The data is transmitted from the sender to the recipient.

For reliable and effective communication, it is essential to use techniques. Flow control and error control are two of them. This article discusses the difference between flow control and error control. The difference between flow control and error control is that flow control is to maintain the correct data flow from sender to recipient, while error control is to determine whether the data being transmitted to the receiver are reliable and error free.
