Road To 200 OCR A Level Computer Science Resources: Protocols Presentation

As Salamu Alaykum Wa Rahmatullahi Wa Barakatuh World!

I said I would do something different after posting 2 Big O Notation resources consecutively so I found this presentation on the networks part of the specification. I think this is the first one on this topic - specifically protocols. Anyway it's really short but it goes through some stuff relevant to the OCR spec. 

Here's the link: Protocols Presentation

Hope this helps!
