Answer:

a. operands are evaluated left toright. 7

b. operands are evaluated right toleft. 12

Explanation:

a. operands are evaluated left toright. 7

b. operands are evaluated right toleft. 12

left to right

int fun (int *i) {

*i +=5; we add 5to x making x 8

return4; we return 4 tomain

}

void main ( ) {

int x = 3;

x = x + fun(&x); x starts at 3 in fun it ischanged to 8 but the 3 is already being used the 4 fromfun is added (3+4) to it making it 7

}

right toleft x starts at 3 in fun x gets changed to 8 and fun is returned as 4so we have 4 + 8 = 12

Paraphrasing

left to right it's is 3 + 4 =7 original value of x is used

right to left it is 4 + 8 =12 x is used as it was changed by fun, since fun was alreadyexecuted

Using the program below, explain what the output will be at LINE A. 1 #include 2#include 3#include 4 5 int value - 128; 6 7 int
slega [8]

Answer:

This is the complete correct program:

#include <stdio.h>

#include<sys/types.h>

#include<unistd.h>

int value = 128;

int main()

{

  pid_t pid;

  pid=fork();

  if (pid==0) /* child process */

  {

  value +=8;

  return 0; }

  else if (pid > 0) {/* parent process */

 wait (NULL);

 printf ("PARENT: value =%d\n" ,value); /* LINEA */

 return 0;

}

}

The output of the LINE A is:

PARENT: value = 128

Explanation:

The fork() function used in the program creates a new process and this process is the child process. The child process is same as the original process having its own address space or memory.

In the child process the value of pid is 0. So the if condition checks if pid==0. Then the child process adds 8 to the value of its variable according to the following statement  

value +=8;

Now the original process has value = 128. In else if part the parents process has the value of pid greater than zero and this portion of the program is of the parent process :

else if (pid > 0)

{ wait (NULL);

printf ("PARENT: value =%d\n" ,value);

return 0; }

So the value 128 is printed at the end in the output.

wait(NULL) is used to wait for the child process to terminate so the parent process waits untill child process completes.

So the conclusion is that even if the value of the variable pid is changed in the child process but it will not affect the value in the variable of the parent process.

You are implementing a RAID storage system and have found a system with eight 100 GB drives. How much storage space will you hav
asambeis [7]

Answer:

The space available will vary between 800 GB (100%) and 400 GB (50%) of the total disks, depending on the RAID level.

The OS will handle the RAID as a single disk.

Explanation:

Each RAID level implements parity and redundancy in a different way, so the amount of disks used for this extra information will reduce the space available for actual storage.

Usual RAID levels are:

<u>RAID 0:</u> does not implement any redundancy or parity, so you will have available 100% of the total storage: 8 x 100 GB = 800 GB

<u>RAID 1:</u> Duplicates all the information in one disk to a second disk. Space is reduced in half: 400 GB

<u>RAID 5:</u> Uses the equivalent of 1 disk of parity data distributed evenly on each disk, meaning the space available is \frac{n-1}{n} of the total disks: \frac{7}{8} of 800 GB = 700 GB

Writting and reading the information on a RAID storage is handled by a raid controller, either implemented in hardware or software. The OS will "see" a single disk and will read or write information as usual.
