Answer the questions based on it.

The PID of the grand-parent of the process with PID 4108623 is :

The two processes which were created by kernel have PIDs  (in increasing order)  and

The process that created most of the "graphical" processes is having PID

How does the distinction between kernel mode and user mode function as a rudimentary form of protection (security) ?

Consider the following programs

exec1.c

#include <unistd.h>

exec2.c

   printf("hello\n");

Compiled as

And run as

$ ./exec1

Explain the output of the above command (./exec1)

Assume that /bin/ls , i.e. the 'ls' program exists.

Select all the correct statements about two modes of CPU operation

Consider the two programs given below to implement the command (ignore the fact that error checks are not done on return values of functions)

$ ls . /tmp/asdfksdf >/tmp/ddd 2>&1

Program 1

int main(int argc, char *argv[]) {

Program 2

int main(int argc, char *argv[]) {
