Why do we need to have flow control and error control discuss with examples?
Why do we need to have flow control and error control discuss with examples?
The method used for error control is called Automatic Repeat Request which is used for the noisy channel….Difference between Flow Control and Error Control :
| S.NO. | Flow control | Error control |
|---|---|---|
| 1. | 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. |
In which two layer the error control and flow control takes place?
Flow control and Error control are the control mechanism at data link layer and transport layer. Whenever the sends the data to the receiver these two mechanisms helps in proper delivering of the reliable data to the receiver.
What is flow control and where it is implemented in OSI model?
In addition, in data communications, flow control is the process which happens between two nodes and tells the sender how much data it can transmit before it must wait for an acknowledgement from the receiver. …
Which layers are responsible for error and flow control in OSI model and how these processes are executed?
Flow control: The transport layer also responsible for flow control but it is performed end-to-end rather than across a single link. Error control: The transport layer is also responsible for Error control. Error control is performed end-to-end rather than across the single link.
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 and where is flow control needed?
Flow control mechanisms can be classified by whether or not the receiving node sends feedback to the sending node. 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.
What is error control in data link layer?
Error control in data link layer is the process of detecting and correcting data frames that have been corrupted or lost during transmission. Data link layer follows a technique to detect transit errors and take necessary actions, which is retransmission of frames whenever error is detected or frame is lost.
What is error control and how it can be implemented?
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.
Is error control a function of network layer?
Error control is basically process in data link layer of detecting or identifying and re-transmitting data frames that might be lost or corrupted during transmission.
