The Restaurant Order System

Think of a restaurant kitchen getting orders. First, the waiter fetches the order slip from the counter (gets the instruction from memory). Then, the head chef decodes it - "Table 5 wants pasta" becomes "boil water, cook pasta, add sauce" (Control Unit interprets the instruction). Finally, the sous chefs execute the tasks - actually making the dish (ALU does the work). This cycle repeats billions of times per second - fetch the next order, decode what it means, execute the steps, then immediately fetch the next order!
