Answer: Remote Access Trojans (RATs) is the malware that is used by the hackers to attack the computer and operating system remotely.The working of RATs is done by download the malware and executing it to create a server .After the server is created ,hacker sends this server along with a crypter to eliminate the antivirus program's function present in the user's system.
Thus, RAT gets invoked in the system of the user and the hacker can control the user's system .Attacker can hack the complete functioning of the user's system and can steal, destroy ,execute etc any confidential data and application.
The user or the network administrator can get to know about the RAT's activity by steps like checking the open port, checking the activities through Task Manager of Windows, observing any unusual activity and appearance of the display screen etc.
Answer:
for(let i = 0: i <=5; i++) {
console.log(I)
}
Explanation:
An iterative statement repeats a body of code until the condition is not true. Here we declare an integer (i) and make it 0. Then the loop checks if the second part is true (i is less than or equal to 5), and if it is true, it executes the code inside the loop body, which logs i, and finally runs the last past, which increments i by one. When the second part becomes false, the loop exits.

Answer:
// program in C++ to check leap year.
// include header
#include<iostream>
using namespace std;
// main function
int main() {
// variable
int inp_year ;
// ask user to enter year
cout<<"Enter year:";
// read year
cin>>inp_year;
// check year is leap or not
if (((inp_year % 4 == 0) && (inp_year % 100 != 0)) || (inp_year % 400 == 0))
// if leap year , print leap year
cout<<inp_year<<" is a leap year.";
else
// print not leap year
cout<<inp_year<<" is not a leap year.";
return 0;
}
Explanation:
Read year from user.Then check if year is divisible by 4 and not divisible by 100 or year is divisible by 400 then year is leap year.otherwise year is not leap year.
Output:
Enter year:1712
1712 is a leap year.
