Consider a books ordering system in order to purchase books. Process order is elaborate below in order to define the logical functions ofthe system. First, incoming orders are checked for correct book titles, author's names, and other information and then batched into other book orders from the same bookstore to determine how may copies can be shipped through the ware house. Also, the credit status of each book stores is checked before shipment is authorized. Each shipment has a shipping notice detailing the kind and numbers of booked shipped. This is compared to the original order received (by mail or phone) to ascertain its accuracy. Thedetails of the order are normally available in a special file or data store, called "Bookstore Orders”. Following the order verification and credit check, a clerk batches the order by assembling all the book titles ordered by the bookstore. The batched order is sent to the warehouse with authorization to pack and ship the books to the customer.…

In a computer system five processes are attempting to proceed with three resource types. The total units of system resources are: (8,9,7). The maximum demands for every process are: P1(3,1,1), P2(3,3,2), P3(5,3,2), P4(5,1,2), P5(8,4,3). The current allocation is: P1 (0,1,1), P2 (2,1,1), P3 (3,1,2), P4 (1,1,1), and P5 (2,3,2). Is this state a safe state? Explain your answer. Please explain in great detail so i can understand .
