Why is flow control needed 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. It is very essential because it is possible for sender to transmit data or information at very fast rate and hence receiver can receive this information and process it.

Why is flow control needed?

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 the need of data link control?

Data Link Control is the service provided by the Data Link Layer to provide reliable data transfer over the physical medium. For example, In the half-duplex transmission mode, one device can only transmit the data at a time.

Which layer is responsible for flow control?

The transport layer
Transport The fourth layer of the OSI model ensures complete and reliable delivery of data packets. The transport layer provides mechanisms such as error control, flow control, and congestion control to keep track of the data packets, check for errors and duplication, and resend the information that fails delivery.

What is the significance of flow control and error control in transport and data link layer?

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 purpose of flow control Mcq?

Solution(By Examveda Team) Flow control allows the receiving device to control the transmitter so the receiving device’s buffer does not overflow.

What is the purpose of flow control in networking Mcq?

What is flow control Where should flow control be done?

Flow control is a mechanism used to help manage the rate of data transfer between two devices. This is done to help prevent a source evice from overwhelming a destination device by sending more packets than the destination can handle.

What is the difference between flow control in transport and data-link layer?

Flow control in transport layer ensures the delivery of the message globally, as the two points of connection over this protocol are logically connected. Whereas in data-link layer, the concern is to deliver message locally, as the two points of connection over this protocol are physically connected.

What is the function of the flow control valve?*?

A very common function of flow control valves is to control the speed of cylinders and air motors. The speed of cylinders or air motors depends on the amount of air, which can be controlled by flow control valves.

Which of the following is true with respect to UDP?

Explanation: UDP is an unreliable, connectionless transport layer protocol that provides message-based data transmission. TCP is an example of connection-oriented protocols.

What is flow control in data link layer?

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. Flow control is actually set of procedures that explains sender about how much data or frames it can transfer or transmit before data overwhelms receiver. Attention reader!

What is the goal of the data link layer?

The goal is consistent learning and absorbing information while feeling engaged and not overwhelmed. I have divided the data link layer articles in five parts. I will be explaining the flow control and error control in the data link layer of the TCP/IP Five-layer network model.

What is flow control in computer networking?

Computer Engineering Computer Network MCA. Flow control is a technique that allows two stations working at different speeds to communicate with each other. It is a set of measures taken to regulate the amount of data that a sender sends so that a fast sender does not overwhelm a slow receiver. In data link layer, flow control restricts

Which layer of the transport layer uses feedback based flow control?

This is used in the network layer and the transport layer. Data link layer uses feedback based flow control mechanisms. There are two main techniques − The sender sends a frame and waits for acknowledgment.
