What is a flow control in computer network?

Flow control is defined, in its broad sense, as a synchronization protocol that dictates the advance of information from a sender to a receiver. Flow control determines how resources in a network are allocated to packets traversing the network. First, basic definitions and types of flow control are introduced.

What is flow control and its types?

Flow control is a technique that allows two stations working at different speeds to communicate with each other. In data link layer, flow control restricts the number of frames the sender can send before it waits for an acknowledgment from the receiver.

What are flow controls used for?

The purpose of flow control in a hydraulic system is to regulate speed. All the devices discussed here control the speed of an actuator by regulating the flow rate. Flow rate also determines rate of energy transfer at any given pressure.

What is flow control and buffering?

FLOW CONTROL AND BUFFERING: Flow control is done by having a sliding window on each connection to keep a fast transmitter from over running a slow receiver. Buffering must be done by the sender, if the network service is unreliable. The sender buffers all the TPDUs sent to the receiver.

What is flow control in Python?

A program’s control flow is the order in which the program’s code executes. The control flow of a Python program is regulated by conditional statements, loops, and function calls. Python has three types of control structures: Repetition – used for looping, i.e., repeating a piece of code multiple times.

What is flow control and error control?

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.

What is the role of 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.

Why is flow control important in computer networks?

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.
