+
+
+## don't panic
+
+* reading the slides & working through the labs gives you everything you need
+* there are 40 short questions at the start of the exam which give you a good chunk of the pass mark
+* don't rush these (there may be a plausible answer which is wrong)
+* plan your revision...
+
+## diagram time
+
+we're going to draw a series of annotated diagrams to represent how our web apps work. 
+
+for each diagram you will work in a small group. the steps will be:
+
+* discuss as a group
+* draw and annotate your diagram
+* a show-and-tell by one or more of the groups
+* a wrap-up
+
+## internet
+
+draw a labelled diagram to represent the working of the internet protocal stack, when a client communicates with a server across the internet. include on your diagram:
+
+* the layers
+* indicate at which layer SMTP operates (SMTP = Simple Mail Transfer Protocol)
+* indicate at which layer SSH operates
+* indicate the numbers used to identify a unique connection between processes at either end (e.g. browser & web app)
