How is the kill() system call different from all other system calls?

Expert Solution

System call:

The system call provides the service to the user and it is a way by which the computer program requests service from the kernel. The kernel manages the key component of the operating system like device management, file management, CPU scheduling, memory management, etc.

The fork() system call is used to create a new process(child process) that will be executed concurrently with the parent process.

The CreateProcess() system call is used to create a new process in Windows operating system. This system call loads the program from the hard disk into the memory and a new process created.

The kill() system call is a request to the operating system to kill the process.

The main difference between the kill() system call and the other call is that the kill() system call urges the operating system to kill the process and this system call doesn't mean that the process will be terminated definitely.

The zombie process can't be deleted by using the kill command.

The following program calls the fork() system call to create a child process. Suppose that the actual pids of the parent process and child process are as follows: Parent process: 801 Child process: 802 (as returned by fork) Assume all supporting libraries have been included. => Use the answer text field to write the values of the pids printed at lines 1, 2, 3, and 4 (indicate each line number and the value printed). int main() { pid_t pid,...

Tel-Skein is a call centre which fields all queries by customers of a national bank. Calls that are put through to operators who specialise in queries regarding ‘Lost or Stolen Debit Cards’ occur at random at a mean rate of 90 per hour. (i) What is the probability distribution, including its parameter(s), of the number of calls arriving in this part of the call centre during a two-minute interval? (There is no need to calculate any probabilities in this part...

At a call center, calls come in at an average rate of four calls per minute. Assume that the time elapsed from one call to the next has the exponential distribution, and that the times between calls are independent. a. Find the average time between two successive calls. b. Find the probability that after a call is received, the next call occurs in less than ten seconds. c. Find the probability that less than five calls occur within a minute....

Historically, evening long-distance calls phone calls from a particular city have averages 12 minutes per call. In a random sample of 20 calls, the sample mean was 10.7 minutes per call with a standard deviation of 4 minutes. Does the sample indicate a change in the mean duration of long distance calls? Test the hypothesis at 10% level of significance, state the hypothesis and report your conclusion. a. estimate the p-value and show your work.
