In a batch operating system, three jobs are submitted for execution. Each job involves an I/O activity, CPU time and another I/O

Ilia_Sergeevich [38]

Answer:

a) CPU utilization for uniprogramming system = 18.2%

b) CPU utilization for multiprogramming system = 41.379%

Explanation:

IO time = total time – CPU time

For JOB 1

CPU time = 3ms ,

total time= 23ms

IO time = 23-3 = 20ms ,

For JOB 2

CPU time =5ms

total = 29ms

IO time = 29-5 = 24ms

For JOB 3

CPU time = 4ms

total = 14ms

IO time = 14-10 =10ms

1.) In uniprogramming system, operations are performed sequentially

CPU utilization=total CPU time / total real time

CPU utilization =(3+5+4) / (23+29+14)

CPU utilization =0.182 or 18.2%

2) In multiprogramming system, jobs wait for the CPU to get free while performing IO operations concurrently

steps followed by the os

1. IO for 1st job at 0ms

2. IO for 2nd job at 0ms

3. IO for 3rd job at 0ms

4. CPU time for 3rd job at 5ms

5. Next IO job for 3rd job at 9ms END at 14ms

6. CPU time for 1st job at 9ms

7. Next IO job for 1st job at 14ms END at 23ms

8. CPU time for 2nd job at 14ms

9. Next IO job for 2nd job at 15ms END at 29ms

CPU time is 3+5+4 =12ms

Total execution time = 29ms

CPU utilization = 12*100/29= 41.379%

What type of game is LEAST LIKELY to need a structured narrative?

VladimirAG [237]

Answer:

Probably a sports game

Explanation:

A role-playing means acting it out, so you need to explain the life with a structured narrative.

An adventure game needs lots of background, so you need to fill that in with a structured narrative.

A sports game revolves solely around sports, so you only need to know how to play the game and/or sport, so no structured narrative is needed.

An fps game needs a structured narrative in that it is similar to an adventure game and needs background.

Let me know if I was right! Hope this helped. :)

What difference between plagiarism and fair use?

Alekssandra [29.7K]

Plagiarism is quite a bad thing because if you plagiarize, you are copying and pasting other people's work and using the work as yours (even though you change the sentence structure/ some words, it is still plagiarizing.) Fair use means un-biasness.

In a school 50% of the students are younger than 10, 1/20 are 10 years old and 1/10 are older than 10 but younger than 12, the r

Zielflug [23.3K]

Answer: 10 students

Explanation:

Students younger than 10 = 50%

Students that are 10years old = 1/20 = 1/20 × 100 = 5%

Students that are older than 10 but younger than 12 = 1/10= 1/10 × 100 = 10%

Students that are 12 years or older

= 100% - (50% + 5% + 10%)

= 100% - 65%

= 35%

This means that 35% of the students are 12 years or older and we've been given the number as 70.

Let's say the total number of students is x. Therefore,

35% of x = 70

0.35 × x = 70

0.35x = 70

x = 70/0.35

x = 200

The total number of students is 200.

Therefore, the number of students that are 10years will be:

= 1/20 × 200

= 10 students

Therefore, 10 students are 10 years.

Which of the following is the most effective password?

zzz [600]

I would have to say that the M3(ury would be the MOST effective, because it has more capitals, numbers, and symbols, which would make it harder to hack into.
