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%

why is it useful to learn how to solve and program solutions with a limited set of command in computer science
12345 [234]

Answer:

Give at least one reason why it's useful to learn how to solve and program solutions with a limited set of commands. So that when there is more commands we know how to use the ones we have. parameters help generalize the solution to a specific problem. how are functions with parameters an example of abstraction?

All it services and servers are equally critical. <br> a. True <br> b. False
g100num [7]

False

Not all IT services are equally critical. In an increasingly digital world whereby cyber threats are a big threat, it is vital to prioritize the critical assets in order to achieve digital resilience. This involves building tighter defenses in systems that are critical.

In the following cell, we've loaded the text of Pride and Prejudice by Jane Austen, split it into individual words, and stored t
Sever21 [200]

Answer:

Explanation:

Since the array is not provided, I created a Python function that takes in the array and loops through it counting all of the words that are longer than 5. Then it returns the variable longer_than_five. To test this function I created an array of words based on the synapse of Pride and Prejudice. The output can be seen in the attached picture below.

def countWords(p_and_p_words):

   longer_than_five = 0

   for word in p_and_p_words:

       if len(word) > 5:

           longer_than_five += 1

   return longer_than_five
