Sorry I'm not there - I know you'll not have nearly as much fun without me! I need you to research circuit and packet switching. It's under the heading of network switching.
You need to be able to describe both circuit and packet switching and understand the differences between them. You will all need your own notes on this in some form.
This is 2 lessons work; I'll either consolidate what you've done and carry on with it tomorrow or, if I'm still poorly, please continue and finish it off yourselves.
If I'm not in tomorrow, please check this Blog again for any further instructions.
Hope that's ok
Hope to see you tomorrow, or if not, soon!
Ms W :-)
