- CPU is expecting to have two things for each application’s process section, a) data (this is ingredients for the cook) and b) Instructions (specific order of the food (recipe)). Consider the below-given parameters while working on questions 2 and 3. The parameters of the OS and Restaurant analogy. CPU: The cook who prepares the food based on given ingredients (data) and instructions. It will receive data and instructions for each process. PROCESS: The food preparation. The customer wants to have/order food. Each food order should be prepared based on customers' needs. Each food order considers to be a process and comes with data and instructions. Customers may order more than one process (i.e. salad, drink, and pizza). That means 3 different processes. Consider the customer as an application in computer OS. In this example, one application comes with three processes. OPERATING SYSTEM: The rules of the restaurant. The restaurant should be run based on these rules.
