Something that has to do with the internet, I get this part. But what are those layers? Are they physical?
I also heard the term: layer 2 switch. What is that, is there a difference between this and a normal switch?
What can be achieved using the OSI model?

So only the first layer is physical. The rest are software (generally).
To keep it simple, the idea is to break up all the complexities of communicating across wires into smaller building blocks that can be stacked up on each other until you get “I type in google, and google appears”.
So maybe think of it like how we speak to each other.
Layer one is, we make physical sounds. Then we can code some of those sounds into words. Then we can take those words and form sentences, and then we can take those sentences and make paragraphs.
