Keyword reference for synchronisation

Question 64 (2000):

I am looking at some of the past papers and have a couple of questions about one of the questions. It asks you to explain the synchronisation of a channel? But all it has in the notes about synchronising is:

              input synchronising  =  input ? x

and the same for output. Is this all it means or is there more? Thanks.

Answer 64:

This is a pretty fundamental issue. If you don't know the answer, then you cannot have been following the course and will not be able to appreciate how any of the exercises or examples work. More likely, you have just been thrown by terminology and really do understand the concepts.

The basic facts of channel synchronisation are given in slides 4-27 through 4-31. This is repeated in sections 3.2 and 3.3 of the "occam2 Checklist" paper in your notes. The idea is assumed by almost everything else in the course.
