10 mcqs from past papers and remaining from last lectures

Q 1 was related to operating system which software is used to control manage the computer functions management name its two types..

Q. define the figure that was from

Book page 129.

Q write 3 semaphore issues..

Q Find logical address of given value..

Q.Find effective time of given value

Q.Is I/O swaps is faster than file system ?explain

Q..Find save sequence of given value. It was from book page 135 example

Cs604 final term paper 2019

20 mcqs were in past waqar sidhu files

Subjectives are

Q1. Describe the operation that a file owner can use for "file protection" .also mention some operations that we can perform on a file.

[Q2. Is disk I/O to swap space generally faster than file system? Justify the statement with reason in either case .

Q3. Write down at least two types of file structure.

Q4. "Virtual Memory is an extremely large main memory"

Do you agree with the given statement or not? Give reason to support your answer.

Q5. Classify the semaphores into at least two categories based on waiting behavior.

Q6.And when a specific semaphore is more useful as compared to other?

Q7: Suppose ,logical adress space =32bits and page size =8k then calculate the following

*Maximum page in a process address space

*Adress bits p(page number)and d(offset)

Q8.: In deadlock prevention strategy do you think it is necessary to check that either safe state exits or not? Give reason to support your answer.

 20mcqz from past 

..

1…suppose that pipe read end descriptors is pfd[0] and write end descriptor is pfd[1] now the process creates a new process using fork now write the read end descriptors and write end descriptors

2… identify the problems

  a…. po               p1

         signal(S)    wait (S)

         wait (S)  signal(S)

b.. po               p1

         wait (S)   wait(Q)

         wait (Q)           wait (S) 

 

signal(S)       signal(Q)

signal(Q)    signal(S)

 

c.. po               p1

wait(S)       wait(S)

wait(S)     signal(S)

 

3…..Name the two registers which are used for segmentation

4…enlist the three different stages when the addreeses can be bound ti instruction and data

5..While managing computers system hardware efficient sometimes it seems reasonable to service all requirements that are closed to cureent position write this technique name

6..code likhna tha   test and set ka

7.classify semaphores in two categories

8.in OS mention five methods to improve access time and bandwidth

9..in LINUX write working of copy on write techchique to virtual memory

10.valueas given then 10kb 4kb 2okb 18kb 7kb 9kb 12kb 15kb

Best or wrost fit ka btana tha 12kb 10kb 9kb ka.
