Neco 2022 Data Processing Question 16
Practice objective / multiple choice question 16 from the 2022 Neco Data Processing examination.
Consider the five steps of a data processing cycle labelled as follows: Input (\(I\)), Process (\(P\)), Output (\(O\)), Storage (\(S\)) and Retrieval (\(R\)). The following ordering constraints must be satisfied: \(I\) must occur before \(P\); \(P\) must occur before both \(O\) and \(S\); and \(S\) must occur before \(R\). No other ordering restrictions apply. How many distinct linear orders of the five steps satisfy all the constraints?
