Real Time Scheduling: Select all statements below that are true EDF scheduling assigns the highest priority to a process with the smallest remaining time until its deadline. RM scheduling assigns a higher priority to processes with shorter periods. Rate Monotonic (RM) scheduling works by dividing the total amount of time available into an equal number of shares, and then each process must request a certain share of the total when it tries to start. If a process has period p, it is activated every p units of time. A real-time system is schedulable under Earliest Deadline First (EDF) when its overall CPU utilization is less than or equal to 1. A real-time system is schedulable under RM when its overall CPU utilization is less than 1.

Software cost estimation

In software engineering, cost estimation defines the calculation of the amount spent on software development and testing. This includes maintenance, managing, buying equipment, user requirement reviews, software, training, and servers. Many methods are developed to estimate the software project cost. Software cost estimation has a major impact on planning and managing a project. The software cost estimation has three estimates like project duration(time), effort(person-month), and cost(dollars).

Real Time Scheduling: Select all statements below that are true
EDF scheduling assigns the highest priority to a process with the
smallest remaining time until its deadline.
RM scheduling assigns a higher priority to processes with shorter
periods.
Rate Monotonic (RM) scheduling works by dividing the total amount
of time available into an equal number of shares, and then each

From past experience, the bank knows that it needs the number of tellers shown in the table below at various times of the day. Bank of Tacoma hires two types of tellers. Full-time tellers work 9am to 5pm, 5 days a week, with 1 hour off each day for lunch. The bank determines when a full-time employee takes his or her lunch hour, but each teller must go between 11am and noon, noon and 1pm, or between 1pm and 2pm. Full-time employees are paid $24 per hour, including a paid lunch hour. The bank can also hire part-time tellers. Each part-time teller works exactly three consecutive hours each day, starting at any specified hour (e.g., 10am-1pm), the same time every day of the week. A part-time teller is paid $16 per hour. To maintain adequate quality of service, the bank has decided that at all…
There are two main types of scheduling strategies: preemptive and nonpreemptive.
There are two ways to cancel tasks and free up resources:
Real-time Scheduling: Choose all true assertions. Rate Monotonic (RM) scheduling divides time into equal parts and requires each process to seek a portion upon starting. RM schedules real-time systems with CPU utilization below 1. When CPU utilization is less than 1, Earliest Deadline First (EDF) may schedule a real-time system. A process is initiated every p time unit. RM scheduling prioritizes shorter processes. EDF scheduling prioritizes processes with the shortest time frame.
