I mentioned recently that in his book The Craft of the Classroom) , Michael Marland provided very useful advice on very practical issues in the classroom, and good routines to ensure a smooth lesson. Routines are good, because pupils know what to expect. They are able to predict what is going to happen, and when. Some pupils, whose home lives are chaotic and unpredictable, may even feel safe because of routines.  Here are some routines that I think are useful for Computing lessons.
