Flow control (data)

Flow control is like playing with a water hose in the garden. When you turn on the water, the water flow comes out of the hose. You need to control the water flow so that you do not waste too much water or damage the hose.

In computers, flow control is the same thing. When two devices communicate with each other, they need to set some limits on how much data to send at a time so that they do not waste bandwidth or damage the connection. They need to be careful, just like when playing with a water hose in the garden.

Flow control is important when data is sent over a network. It makes sure that data is sent at the right speed and not too fast or too slow. Flow control also makes sure that data is not lost during transmission. It's like traffic on a highway - If the traffic moves too fast or too slow, there can be an accident or traffic jam.

To summarise, flow control is a way of making sure that data is sent at the right speed and not too fast or too slow so that it reaches its destination successfully without any loss.
