Point-to-Point Protocol over Ethernet

Hey buddy, today I'm going to explain to you about a topic called Point-to-Point Protocol over Ethernet, but don't worry it's not as complicated as it sounds.

PPP stands for Point-to-Point Protocol, which is like a language used by computers to talk to each other. They use this language to transfer data or information just like how you talk to your friend using words.

Now, Ethernet is a way of connecting computers together to share information, it's like a big network of friends in your school, all talking to each other.

When we use PPP over Ethernet, it means we are using the PPP language to transfer data between computers in an Ethernet network.

It works like this: imagine you have two friends who want to share a secret message, but they don't want anyone else to know what it is. They can put the secret message into a special envelope, seal it and give it to a friend who is going straight to the recipient. This is called a point-to-point connection because there are only two people involved.

In the same way, when we use PPP over Ethernet, we create a special envelope or “packet” of information that is put on the Ethernet network and travels to the other computer through a point-to-point connection.

It's like sending a secret message to your friend without anyone else knowing what's in it, as the packet containing the information is encrypted to protect it from being read by anyone else on the network.

So basically, PPP over Ethernet enables computers to communicate with each other through a secure point-to-point connection on a bigger Ethernet network. It's like the private language that helps them understand each other better.
