What do you mean 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 flow control in data communication?
In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. Flow control should be distinguished from congestion control, which is used for controlling the flow of data when congestion has actually occurred.
What is flow control Example?
Xon-Xoff is an example of a flow control protocol that sync the sender with the receiver. It transmits a transmit off signal when the receiver no longer has space in its buffer and a transmit on signal when the receiver can resume taking data. Xon-Xoff works on asynchronous serial connections.
Which of the following is flow and error control techniques?
Flow & Error control techniques: Stop-and-Wait ARQ, Go-Back-N ARQ, and Selective Repeat ARQ.
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 flow control in Java?
Java compiler executes the code from top to bottom. The statements in the code are executed according to the order in which they appear. However, Java provides statements that can be used to control the flow of Java code. Such statements are called control flow statements.
What controls the flow of information in computer?
The control unit (CU) is a component of a computer’s central processing unit (CPU) that directs the operation of the processor. … It directs the flow of data between the CPU and the other devices.
What are the types of flow control?
The most common valve types in flow control industries include:
- Gate valves.
- Globe valves.
- Pinch valves.
- Diaphragm valves.
- Needle valves.
What is the meaning of error control and its types explain in detail?
Error control in data link layer is the process of detecting and correcting data frames that have been corrupted or lost during transmission. In case of lost or corrupted frames, the receiver does not receive the correct data-frame and sender is ignorant about the loss.
What are error control techniques?
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.
What is the use flow control in data link layer?
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.
