CSP is a process algebra which is used to describe parallel programs. In this world, a program is a network of processes, which are connected using channels. The first process to arrive at a channel will wait for the second one. When the second process arrives, it wakes the other one up, the data is coppied and both processes carry on as before. Even though a channel connects them, it doesn't have to be used.
