in C++ please create a Priority : -pre-emptive algorithm code: here are information that will help you Tasks: • Lab 4: Process management • Review Process management algorithms Definitions: (in terms for this lab not formal definitions) • Preemptive: When a new process arrives and has a higher priority than the current running process, Then the current running process is paused and put back in the waiting queue, and the new process starts executing. In most systems it will automatically interrupt the current running job when the new job arrives, however some systems use a predetermined interval (a certain number of time units), to check for new jobs. • Non preemptive: Take no action when a process with higher priority arrives,when a new process with a higher precedence arrives current running process need to finish first before the new process goes Oxford definition: Preempt – to take action in order to prevent (an anticipated event) from happening; forestall. • Metric: a metric is…
use java and javaFX A simple Library Management System aims at developing a computerized system to maintain all the day-to-day activity of a library. This functional project handles data of books and their copies, users that can be either students or teachers as well as book loans, Each book has an id, title, publisher, author, year, number of copies, copies of the book, financial value and status(true if at least one copy is available). Each copy has id, status whether a copy is available to be borrowed of not and insert date. A user has id, first name, last name, password and registration date. In addition to the total fine which is the total of each fine the user get for every late return of a book. Students has major whereas staff has department. When borrowing a book, the system recording the copy of the book being issued (borrowed), the borrower and the date at which borrowed. The system must first check for the copy availability and record the return date which is 3 days from…
Intro to software engineering: A company specializing in consumer electronics requires an order processing systemto be developed that is easy-to-use by its employees, and provides a good responsetime of less than five seconds. Orders are received from customers online who muststate the items and expected delivery deadlines. The orders are recorded andprioritized according to stock availability, transport capacity, delivery deadlines, andtime of order. The output from the system will be the price of the order, and thedelivery date. The customer then has the option to confirm or reject the order. Usingan appropriate modelling technique with supporting notation, and stating anyassumptions made, produce the summary of the problem requirements in the form ofa table that clearly differentiates functional and non-functional requirements;
Programming Project: Scheduling Algorithms This project involves implementing several different process scheduling algorithms. The scheduler will be assigned a predefined set of tasks and will schedule the tasks based on the selected scheduling algorithm. Each task is assigned a priority and CPU burst. The following scheduling algorithms will be implemented: First-come, first-served (FCFS), which schedules tasks in the order inwhich they request the CPU. Shortest-job-first (SJF), which schedules tasks in order of the length of the tasks’ next CPU burst. Priority scheduling, which schedules tasks based on priority. Round-robin (RR) scheduling, where each task is run for a time quantum (or for the remainder of its CPU burst). Priority with round-robin, which schedules tasks in order of priority and uses round-robin scheduling for tasks with equal priority. Priorities range from 1 to 10, where a higher numeric value indicates a higher relative priority. For round-robin scheduling, the…
Draw an activity diagram that models the following employee reimbursement process: Employees of a university have to follow a specific procedure to get reimbursed for travel they undertake on behalf of the university. First, in order to prepare a reimbursement request, they have to do the following activities at the same time: gather all of the receipts the university requires for reimbursement and complete the official reimbursement form. They then submit both the receipts and the form to their departmental secretary for checking purpose. If something on the form is incorrect, the secretary returns the form to the employee and ask for correction. If the form is correct, the employee is asked to review the reimbursement amounts, which are determined by an analysis of the reimbursement request. If the amount shown is not correct, the employee must indicate that this is the case. If the amount shown is correct, then the employee": responsibilities for reimbursement are complete.
Problem Statement: A famous product photographer Xavier is in high demand and is being approached by various companies to get their products photographed. Xavier does all of this product shoots at his studio and wants to make sure that he maximizes his returns by covering as many photoshoots in a day as possible. For a product shoot to be conducted, the product first has to be staged and then photographed. He has a team who stages the products and he does the photoshoots. Depending on the product, it takes different amounts of time to stage and varied time to complete the shoot. His team can stage another product in another part of the studio while Xavier is busy with a photoshoot of a previously staged product. Assuming that his team can work on only one product at a time before they move to staging another and Xavier also finishes one product photoshoot before moving to the next, you are expected to help Xavier make best use of his team and his time by deciding the order in which the…

Process Scheduling: Select all statements below that are true The time quantum T for RR should be larger than the average CPU demand between two I/O operations (CPU burst) of 80% of the processes. Round Robin (RR) imposes a fixed time quantum (time slice) on the amount of continuous CPU time that can be used by a process. Shortest Job First (SJF) is a preemptive scheduling method. Waiting time refers to the time a processor spends in the ready state waiting for the processor. First-In / First-Out (FIFO) scheduling assigns higher priorities to processes that arrive earlier. Shortest Remaining Time (SRJ) is a nonpreemptive version of SJF.
COPY FROM CHEGG == DISLIKE AND REPORT Assume that a finite number of resources of a single resource type mustbe managed. Processes may ask for a number of these resources and will returnthem once finished. As an example, many commercial software packagesprovide a given number of licenses, indicating the number of applications thatmay run concurrently. When the application is started, the license count isdecremented. When the application is terminated, the license count isincremented. If all licenses are in use, requests to start the application aredenied. Such a request will be granted only when an existing license holderterminates the application and a license is returned. The following program segment is used to manage a finite number of instancesof an available resource. The maximum number of resources and the number ofavailable resources are declared as follows: #define MAX_RESOURCES 5 int available_resources = MAX_RESOURCES; /** When a process wishes to obtain a number of…

For example, a one liter container is permitted to contain between 997 cm3 and 1,003 cm3. Design a test suite for testing the company’s quality control using a liter container of a different amount of chemical for each different test case.
Computer Science Class diagram and Object diagram Answer the following questions based on the scenario below of a Request For A Cleaning System. Busy Bees Home Cleaning Service employs a number of cleaners that take cleaning jobs from a central dispatch service. Customers can request a cleaning job by phoning in and making an appointment. The employee that takes the call checks if there is sufficient staff for the appointment. If there is, the employee records the customer and appointment. If there isn’t the staff member suggests other times that are available. Customers can also request a regular cleaning service (e.g. weekly), as well as a specific cleaner. If there is any variation in the job (e.g. the customer requests that windows be cleaned in addition to the normal cleaning job) the cleaner informs the office before the bill is credited to the customer’s account. Most customers are charged via their credit card; regular customers can have an account whereby they are invoiced on…
