Ethernet flow control

Imagine you have a toy car track and you're trying to race your cars around it. But sometimes, the cars are going so fast that they crash into each other, causing a traffic jam. Ethernet flow control is kind of like a traffic cop that keeps the cars from crashing into each other.

In a computer network, devices use something called Ethernet to communicate with each other. Ethernet flow control is a method that helps these devices communicate more effectively. When a device (like a computer or printer) sends data to another device, it can tell that device to slow down if it's receiving too much data too quickly. Think of this like a person telling their friend to talk slower because they can't understand what they're saying.

This helps prevent network congestion, which is when there's too much data going through the network and it slows everything down. Ethernet flow control basically helps to manage the flow of data so that the network can handle it more efficiently.

So, let's go back to the toy car track. Imagine the traffic cop is controlling how fast the cars can go around the track so that they don't crash into each other. Ethernet flow control does something similar - it controls how much data can be sent at once so that the network doesn't get backed up and cause problems.
