Okay, so imagine you have a bunch of toys in your room, and you want to be able to play with them all at the same time. But you have to pick them up one at a time, and you can only hold a few in your hands at once. That's kind of like how computers used to talk to each other. They would send messages one at a time, and they could only send a little bit of information at once.
But now imagine your room has a really cool clear tube that connects all your toys together. Now you can can play with all your toys at the same time, and you can see them all through the tube. That's kind of like what a fibre channel network does for computers. It connects them all together in a really fast way so they can talk to each other really quickly and send lots of information at once.
Now, to make sure everyone can talk and play nicely, there are some rules that the computers have to follow. These rules are called protocols. In a fibre channel network, the protocols make sure that everyone is sending their messages in the right order and that they don't get mixed up with other messages.
Think of it like having a special language you use with your friends. You might say things like "pass the blue toy" or "can I play with the yellow car?" In a fibre channel network, the computers use special language too. They say things like "I need to read this file from that computer over there" or "I'm sending this message to everyone in the network."
So, in summary, fibre channel network protocols are rules that computers follow when they're talking to each other over a really fast connection. The protocols make sure that everyone is speaking the same language and that their messages don't get mixed up. It's kind of like having a cool tube that connects all your toys together so you can play with them all at once.
