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.

Congestion Control: control traffic entry to avoid congestive control. once Congestion occurs the traffic will wait to recover from it.

∙ 14y agoFlow control may cause a sending network to pause when the receiving network is overwhelmed with traffic. The receiving network can signal the sending network to temporarily stop and then to resume traffic once it gets caught up with the traffic.
Error detection occurs when a receiver has detected a corrupted packet and needs to have it resent.

What is difference between electrical and electricity?
Electrical is an one type of energy ie flow of electrons... this flow of electrons constitutes the Electricity which we are using for our use
What is the difference between power and current?
It's the difference between pressure and flow. The pressure is measured in volts, and the current in amps.Current is the flow of electrons.Power=VIcosϕV=voltageI=currentCosϕ=cosine of angle between V and IAnswerCurrent is a drift of electric charge, expressed in amperes. Power is the rate of doing work, expressed in watts (equivalent to a joule per second).
What is the function of Substrate in MOSFET?
it will control the flow of electrons between the source and drain,the controlling will be depends upon the input voltage to the substrate.
Which electrical protective device is designed to detect a difference in a current between circuit wires and interrupt the circuit and stop the flow of electricity?
A resistor is a device designed to detect difference in current and stop the flow of electricity. On most every type of electric engine or circuit has a resistor.
What came first the voltage or the current?
For a current to flow between two points, those points must have a potential difference (voltage) across them.
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
How can you control the congestion in tcp?
The techniques include End-system flow control, Network congestion control, Network based congestion avoidance and Resource allocation.
What is difference between datalink layer flow control and transport layer flow control?
The difference between datalink layer flow control and transport layer flow control is the need to keep the different layers of data separate in the flow control option.
What manages data delivery if there is congestion on the host?
Flow Control
How does congestion control and QOS related?
In congestion control, the load on a network is prevented from exceeding the capacity. Quality of service refers to the characteristics that a flow of data seeks to attain. If there is good congestion control, then the QoS is also good and vice versa.

What is the difference between flow and motion?
the difference between flow and motion is well flow is like floating and motion is the way you move
What mechanism is used by tcp to provide flow control?
the station window size the congestion window memory buffers receipt acknowledgement
