- Do java object oriented full project source code Implement a project that will apply knowledge in JAVA object-oriented programming to manipulate records of information for a system. Apply array of objects or linked list of objects to store the records. The project shall consider the following requirements: 1. Demonstrate the following methods with records of objects: create and insert new object, remove existing object, search object, update object, and display object(s). 2. Be logical in the design of the solution – implement at least 3 classes including main() class, apply inheritance, create linked list of objects or array of objects, input validation. 3. Implement tasks to manipulate records in producing meaningful output – (e.g. apply searching and/or sorting to generate reports, perform calculation and others) *Use all knowledge (classes, objects, array of objects, exception handling, inputs, outputs, files) when developing the program. Topic: Student record system…Operating System Structures: Select all of the following statements that are true. Ring 0 of the onion model of the layered approach to operating system structuring is the innermost ring and corresponds to kernel mode. An operating system's user mode (a privilege level) offers access to privileged commands, which are reserved for the kernel components of the operating system. The traditional UNIX kernel is an example of a microkernel.Assignment 4: RPC/RMI Exercises 1. Design a SciCalculator function and call it with RPC. 2.

- please write with proper explanation. Question half solution is here please write what is main disadvantages of this approach? Half solve questions: Mutual Exclusion: Mutex is an abbreviation for Mutual Exclusion. It is a programme object that prevents multiple users from accessing a shared resource at the same time. When a process accesses a shared variable, it is said to be in the critical section. When no two processes are present in the critical section at the same time, this is referred to as Mutual Exclusion or Mutex. while (true) { semaphore sem = S; while (S <= 0) do no operation { S = S-1; wait (S); } /*critical section*/ while (S > 0) { S = S+1; signal (S); } /*remainder section*/ }B1.

- Q-5: A semaphore for a resource with four channels is defined by the following structure (after multiple operations running for some time ending with the three waits shown below) Process 100: wait( s1); Process 101: Process 105: wait(s); wait(s1); This produces the current values of the semaphore as: semaphore s1 { } value = -3; *list={100, 101, 105) // processes will be awakened in order from left to right Describe how the semaphore value and list change for the following sequences: What is *list and value? What is list and value? What is *list and value? What is list and value? What is list and value?
