<span>If your computer has a rootkit, someone else can gain access to it undetected.
</span>The term rootkit denotes a set of software tools <span>typically malicious.
 The purpose of this software is to enable access to a computer or areas of its software that is not otherwise allowed.

Answer:
- Code is in JAVA language. As there is no user input the logic is straightforward.
- Below is the code along with a detailed explanation of the logic.
- The class name is Print main save as file as the main class. 
Explanation:
Program:-
public class Main{
public static void main(String args[]){
/* There are two for loops...
* First for loop runs from i=1 to i=9
* Second for loop runs from j=1 to j=i.
*
*/
for(int i=1;i<=9;i++){
for(int j=1;j<=i;j++){ // j loop runs from j=1 to j=i
/*Prints I and j next to each other*/
System.out.println(i+""+j);
}//for loop of j ends here
}// for loop of I ends here
}
}
 
        
             
        
        
        
Answer:
Option d) B is 1.33 times faster than A
Given:
Clock time, 
 
No. of cycles per instructions,  

Solution:
Let I be the no. of instructions for the program.
CPU clock cycle,  = 2.0 I
 = 2.0 I
CPU clock cycle,  = 1.0 I
 = 1.0 I
Now, 
CPU time for each can be calculated as:
CPU time, T = 


Thus B is faster than A
Now,


Performance of B is 1.33 times that of A
 
        
                    
             
        
        
        
Answer:
an algorithm (pronounced AL-go-rith-um) is a procedure or formula for solving a problem, based on conducting a sequence of specified actions. A computer program can be viewed as an elaborate algorithm. In mathematics and computer science, an algorithm usually means a small procedure that solves a recurrent problem.
