Three periodic processes with the following characteristics are to be scheduled: (D is the period and T is the total CPU time).   Picture2.png For each case, determine if a feasible schedule is likely to be generated by: • RM • EDF

(Please refer back to the previous problem or two to remind yourself about Jack’s original home purchase).After 6 years in California, Jack has found much success in his job and has even found “the one”!  They want to refinance his home into both of their names and get a 15 year mortgage.  How much will they be refinancing the home for at this time?

What do interrupts and traps have in common? What are the differences between the two concepts?

Three processes, p1, p2, p3, arrive at the same time and start executing using RR scheduling. p1 starts first, followed by p2, and then p3. The respective total CPU times of the 3 processes are 8, 3, 5 time units. The context switching time is negligible.a) Determine the average turnaround time, ATT, when the quantum is Q = 1 time unit.b) Determine the average turnaround time, ATT, when the quantum is Q = 3 time units.

Jack has just graduated from Texas A&M and taken a job making a very nice salary!  The job is in California and although he did not realize how expensive homes were there he has found a house he really likes.  It is listed at $2,750,000 and his family has gifted him 15% for the down payment.  He secures a loan for the rest at 6.49% interest.  He will make monthly payment for the next 30 years.  Using the payment you found in the previous problem, write out what you need to type in your calculator (in one line) in the blank below to determine the INTEREST Jack will pay if he stays in the home for the 30 years. NOTE: For example, 3*4*5 – 2 _______ Now in the second blank below, please type out the INTEREST. Please format your answer with a ‘$’ and rounded to 2 decimal places where needed. For example, $1234.56 _______

Use your TVM Solver on your graphing calculator to solve the problem below: Jack has just graduated from Texas A&M and taken a job making a very nice salary!  The job is in California and although he did not realize how expensive homes were there he has found a house he really likes.  It is listed at $2,750,000 and his family has gifted him 15% for the down payment.  He secures a loan for the rest at 6.49% interest.  He will make monthly payment for the next 30 years.  Using your information you found in the previous problem, determine Jack’s monthly payments.

(Yes, this is the SAME Jack as in the previous problem). After 6 years in California, Jack has found much success in his job and has even found “the one”!  They want to refinance his home into both of their names and get a 15 year mortgage.  They are able to get a loan for 3.325% interest.   How much will their new payment be?(keep in mind the new amount for PV and shorter time!)
