Hey there! So, Link Layer Discovery Protocol is a way for devices to talk to each other and figure out if they can work together to send data.
Think of it like this: when you go to a new school, you need to make new friends so you can do things together, like play during recess. Your computer needs to make friends too, so it can talk to other devices and send data between them.
That's where LLDP comes in! It's like a language that devices can use to introduce themselves to each other. They can say things like "Hi, I'm a computer and I can send data using Ethernet" or "Hi, I'm a printer and I can receive data using Wi-Fi."
This helps devices figure out how they can work together to send data. It's like making a plan with your friends for what game to play during recess. Without LLDP, devices might not know how to talk to each other, and data could get lost or not be sent at all.
So, in summary: LLDP helps devices talk to each other and figure out how they can work together to send data. It's like making friends at a new school!
