If a sporadic implicit deadline task set is schedulable under RM, will it be schedulable under RM after enlarging one of the deadlines (now it becomes an arbitrary deadline task set)? Note that we are still following the original RM priority order (not DM). What if we follow DM order?
In a Computer System, there are 4 processes namely Chrome, Teams, Zoom and Skype that arrived at the same time. Processes are executed based on priority : Zoom has highest priority, then Skype, after that Chrome and finally the Teams. Process Chrome Teams Burst time 25 33 Zoom 52 Skype 76 Consider this scenario in terms of Process Scheduling Algorithm and answer the following. a) Draw a Gantt chart in a paper for the above scenario capture an image, upload it in Moodle c) Find the Average Turnaround Time. d) Find the Average Waiting Time.

Suppose a team creates a shared spreadsheet that lists all pending tasks. Each team member picks a task and moves it to a separate worksheet in the file. When that task is completed, its owner moves it to a third worksheet. The team checks in regularly to ensure work is distributed evenly and no task is held up waiting on another. Which methodology is this team using? A)waterfall B) scrum C)Kansan D) extreme programming
P and Q are two processes that share a set of variables that is common. The variable includes: seq, tA and tB: Before either process starts to execute, variable seg initially has the value 10. State the possible sets of different values of seg when both processes have finished executing. Provide an order of execution of statements from processes P and Q that would produce each of the values you give. Justify your answer in detail. P P1: tA= seq + 1; P2: seq = tA; tily has the value 10. Q Q1: tB = seq+ 2; Q2: seq = tB;
