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. Like in the…

Which of the following are true with respect to a mutiprogrammed, time-shared (multi-tasking) environments? (Select all that apply.) Context-switching provides optimal use of the CPU by scheduling ready processes as soon as the CPU is available. Context switching is a zero cost operation. There is better performance when the multiprogramming level is very low. Critical sections and race conditions are a direct result of context switching and programs sharing memory.

Create a process model for the following simple scenario using BPMN. In an online shopping application, the following steps will be followed whenever a customer places a new order. The shop receives an order from a customer to buy a product. The availability of the product will be checked. If the product is available, the order will be shipped to the customer. If the product is not available, a request for the order will be sent to the supplier, then it will be shipped to the customer.
P and Q are two processes that share a set of variables that is common. The variable includes: seq, tA and tB: Before either process starts to execute, variable seg initially has the value 10.
