What are flow-control methods?
Sliding Window Stop and Wait
What is the advantage of sliding window flow control over stop-wait flow control?
As compared to stop-and-wait flow control the sliding window flow control has a far better performance. This is because in a wireless environment data rates are very low and noise level is very high, so waiting for an acknowledge for every packet that is transfered does not seem feasible. Thus,Transferring data as a bulk ( Once the medium is allocated ) would yield a better performance in terms of higher throughput. So the choice is sliding window flow control. Sliding window flow control is a point to point protocol assuming that no other entity tries to communicate until the current data transfer is complete by truqchalar

What size is a sliding window for a device that uses the stop and wait flow control method?
A single frame
What mechanism is used by tcp to provide flow control?
the station window size the congestion window memory buffers receipt acknowledgement
Are the objectives of flow control and congestion control the same?
Average rate will remain same but Flow control: end-to-end mechanism for regulating traffic between source and destination • Congestion control: Mechanism used by the network to limit congestion
Which layer is responsible for flow control with sliding windows and reliability with sequence numbers and acknowledgements?
Transport layer
How does a faucet work to control the flow of water in a sink or bathtub?
A faucet controls the flow of water by using a valve mechanism to regulate the amount of water that is released. When the handle is turned, the valve opens or closes to allow more or less water to flow through the spout. This mechanism helps to control the water pressure and temperature, allowing the user to adjust the flow of water to their desired level.
What is the difference between flow control and congestion control?
Flow control vs. congestion control: Flow control means preventing the source from sending data that the sink will end up dropping because it runs out of buffer space. This is fairly easy with a sliding window protocol--just make sure the source's window is no larger than the free space in the sink's buffer. TCP does this by letting the sink advertise its free buffer space in the window field of the acks. Congestion control means preventing (or trying to prevent) the source from sending data that will end up getting dropped by a router because its queue is full. This is more complicated, because packets from different sources travelling different paths can converge on the same queue.
What mechansim is used by tcp to provide flow control as segments travel from source to destination?
Window size
Why is the sliding collar on a Bunsen burner?
The sliding collar on a Bunsen burner is used to control the air flow into the burner. By adjusting the collar, you can regulate the amount of oxygen mixed with the gas, which affects the flame's size and temperature.
What the different valve sdnr and globe valve?
A globe valve is designed for throttling flow and provides a spherical body shape that allows for precise control of fluid flow. It features a movable disk or plug that can be raised or lowered to adjust the flow rate. In contrast, a SDNR (Sliding Disc Non-Rising) valve is a type of valve that uses a sliding disc mechanism to open and close, often offering quicker operation and a more compact design. While globe valves are typically used for regulating flow, SDNR valves are often favored for on/off applications in systems where space constraints are a concern.
