(a) The set of tasks T = {(5, 2),(8, 3),(10, 1)} is scheduled by the rate-monotonic algorithm.
(b) The set of tasks T = {(3, 1),(6, 1),(18, 6),(36, 4)} is scheduled by the least-slack-time-first algorithm.
(c) The set of tasks T = {(3, 1),(0, 6, 1, 4),(18, 6),(36, 4)} is scheduled by the earliest-deadline-first algorithm.
(d) The set of tasks T = {(3, 1),(6, 1),(18, 6),(36, 4)} is scheduled by the deadline-monotonic algorithm
Design a real time system to update a real time database. The data needs to be consistent and atomic transactions need to be performed serially. Identify the basic tasks required.
Explain what type of system it is i.e. either HARD /SOFT OR FIRM and justify your answer.
Also mention what type of scheduling algorithm can be used and justify your answer.
Also say whether it is online or offline scheduler and justify your answer.
