In a data directory, a 01 is the smallest piece of data that has meaning within an information systems.
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.

A cloud service providers uses KVM in their data centers because they are gravely concerned with insider threats.
KVM is a system for management, monitoring and control of a data center environment from a central location. In the data center this system is very necessary because the data center has multiple servers and computers. With this system the server can be connected and controlled from a remote location. This includes mapping the physical locations of accessible virtual drives.
Your question is incomplete, but most probably you full question was:
Modern managed cloud service providers will often use secure Keyboard/Video/Mouse (KVM) devices within their data centers. these devices are extremely expensive compared to their non-secured counterparts. which of the following is one of the reasons cloud service providers do this?
- They have plenty of revenue and can afford it
- They are gravely concerned with insider threats
- Cloud data centers need very few of these devices
