one data is in memory the computer interpets and executeinstructions to process the data into informationA. TrueB. False

lidiya [134]

Answer:

Option A is the correct answer for the above question.

Explanation:

The computer is a system that processes the data to produce information. For any computer system when the data is processed then it will form the information.
The user gives some instruction to process that can also be called the program. Then the computer takes the instruction and processes the data on behalf of the instruction and for the information because in any system when data is processed it can form the information.
The above question says that the computer follows the instruction to process the data to produce the information which is correct as described above. Hence True is the correct answer to the above question.

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%

SCORPION-xisa [38]

Answer:

Folksonomy.

Explanation:

A system of classifying and organizing online content into categories by the use of user-generated metadata such as keywords is called a folksonomy.

This ultimately implies that, folksonomy is a user-generated system which is typically used for classifying and organizing online content into various categories through the use of metadata such as keywords, electronic tags and public tags in order to make it easier to find in the future.

Hence, folksonomy is highly beneficial in areas such as collaborative learning, teacher resource repository, collaborative research, educational platforms, e-commerce etc.
