The console connection enables you to have privileged access in the switch which is otherwise not available for <span>telnet or ssh most especially if a password and or secet is enabled in this specific switch. In some cases, the console access is blocked. If this is the case, you can use the end device (PC or laptop) to control the swicth provided it has the required applications to do so.</span>

If we talk about switch Cisco 2960, you must use a console connection instead telnet or ssh to initially configure the switch because, it has no networking services configured when it's first placed and there are no IP addressing parameters configured.

Three of the following values could be stored as strings. When would you NOT use a
kifflom [539]

Answer:

To store decimal values

Explanation:

If values are not to be used for calculation, that is, they are not numerical data, therefore, some of them could be stored as strings. A string may contain any sequence of characters. The characters in a string may be repeated.

From the foregoing, decimals can not be stored as strings because in computer programming, a string is normally a sequence of characters, hence the answer above.

The ArrayList class ____ method returns the current ArrayList size.
timurjin [86]

Answer:

b. size

Explanation:

We can use the size() method of java.util.ArrayList to determine the size of an  ArrayList in Java. The size() method of the ArrayList class returns an integer which is equal to the number of elements present in the ArrayList.

Below is an example code to illustrate the use of the size() method of the ArrayList:-

     ArrayList<Integer> aList = new ArrayList<Integer>(5);

      aList.add(25);

     aList.add(2);

     aList.add(5);

     aList.add(22);

     System.out.println("Size of the array list: " + aList.size());

This will print the size of the array list as 4 since we've added four numbers into the array list.

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.
