## Resource Allocation Diagram AnalysisIn the provided resource allocation diagram, we have three processes labeled P1, P2, and P3 corresponding to three resources: Processor, I/O, and Main Memory. The diagram uses solid and dashed lines to indicate the allocation and waiting states of resources by processes.**Key:**- **Solid Line:** The resource has been allocated to the process.- **Dashed Line:** The process is waiting for the resource.### Diagram Explanation:- **P1:** - Has a solid line connecting it to the Processor, indicating that the Processor is currently allocated to P1. - A solid line connects P1 to I/O, showing that P1 is also allocated the I/O resource. - **P2:** - Displays a solid line to the I/O resource, indicating it is allocated the I/O resource. - Has a dashed line pointing towards the Processor, signifying P2 is waiting for the Processor. - Also has a dashed line toward Main Memory, meaning P2 is waiting for it as well. - **P3:** - Shows a solid line leading to Main Memory, indicating that Main Memory is allocated to P3. - Dashed lines connect P3 to the I/O and Processor, indicating P3 is waiting for both these resources.### Analysis of Process States:- **P1** is in a running state since it has both the Processor and I/O resources needed for its operation.- **P2** is in a waiting state because it lacks both the Processor and Main Memory.- **P3** is also in a waiting state because it requires the Processor and I/O resources to proceed.This diagram illustrates a typical allocation scenario in operating systems, helping visualize how resource allocation and process scheduling might work, which is critical for avoiding deadlocks and optimizing performance within a system.

The Algorithmic Flow of the process running is as follows.Step.1) In the queue for executionStep.2)…

Derive the states of the three processes P1, P2 and P3 from below resource allocation diagram and explain why. (A solid line. indicates that the resource has been allocated to the process; a dashed line means that the process is waiting for the resource)

2) Draw an use case diagram according to the below scenario: MAIN FLOW • The user could be student and staff. • The user request for book, reserve a book and renew a book (although rare, the user enter invalid renewal) • The user can view the book information . At the same time, the user may search for book. The user pays for fine and also give feedback. • The user can also register as new user. • The librarian can add record, delete and updatate a book record (although rare, the librarian enter invalid ID) EXCEPTIOANAL CONDITION The user and librarian must be authenticated to finalize the process. It could be done through user login page, user authentication cookie ('remember me') or single sign on. Although rare, they enter invalid username and password. • The user must fill in up feedback form for giving feedback. • The user must fill in up registration form and get library card id for registering as new user. The librarian must update the record id for updating the book record. The…

Given a system of 4 processes with a set of constraints described by the following precedence relation: › : {(P1, P3), (P1, P4), (P2, P4)} The processes access memory locations according to the table attached. Answer the following questions about the system (you are not required to draw any graphs): 1. Is the system determinate for all interpretations of its processes? Explain why. 2. Is the process pair (P3, P4) mutually non-interfering (MNI)? Explain why. 3. If the process pair (P3, P4) is not MNI, what modifications are necessary to guarantee that the system is determinate for all interpretations?
b. You are modelling a working of a Business Process Organization (BPO) and trying to visualize handling two types of queries – 'order-queries' and 'request- queries.' There are three workers in the model – worker-1, worker-2, and worker-3. In the BPO, 'order-queries' will only be handled by worker-1. 'Request-queries' can be taken by any worker; however, workers operate sequentially and must not handle consecutive 'request-queries', i.e., 'request- queries' will be dealt with by worker- 2 if previous request was taken by worker- 1 and so on. Design a DFA that Accepts if the last 'request-query' is handled by worker-3, or worker-1, or the 'order-query' by worker-1. Assume that the first order or 'request-queries' arrive at worker- 1. [Hint: Use workers as states]
When there are several processes going on at the same time, what sort of a response does the capacity analysis get?
A process should be allowed to access only those resources for which it has authorization. Furthermore, at any time, a process should be able to access only those resources that it currently requires to complete its task. This is commonly referred to as the need-to-know principle, or domain of protection. Discuss this “domain” and its structure, including the following: Whether the relationship between a process and a domain is static or dynamic Domain switching How domain switching happens in the following cases: Each user is a domain Each process is a domain Each procedure is a domain
