Answer:

B. xfs_fsr

Explanation:

<em>xfs_fsr</em> is used for  Defragmentaion of xfs files. It works by improving the organization of the disk extents of every file to ensure that contiguous space is being used.  This tool performs online defragmentation meaning that it can be run on a file system that is currently mounted and in use, just be aware of the increased I/O usage that will come as a result , it may be best to run it during a period of low disk activity if possible on a production system.

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%

Ksenya-84 [330]

Answer:

shortNames = ['Gus', 'Bob','Zoe']

Explanation:

In this assignment, your knowledge of list is been tested. A list is data structure type in python that can hold different elements (items) of different type. The general syntax of a list is

listName = [item1, "item2", item3]

listName refers to the name of the list variable, this is followed by a pair of square brackets, inside the square brackets we have items separated by commas. This is a declaration and initialization of a list with some elements.

The complete python code snippet for this assignment is given below:

<em>shortNames = ['Gus', 'Bob','Zoe']</em>

<em>print(shortNames[0])</em>

<em>print(shortNames[1])</em>

<em>print(shortNames[2])</em>
