Explanation:
Every change that an operating system experiences (user logs on, useropens application, application communicates to another application, user inputsdata, and so on) is considered a state transition. a very technical sense alloperating systems and applications are just lines and lines of instructions that arewritten to carry out functions on data. The instructions have empty variables, whichis where the data is held.
