Some of the disadvantages of using layered protocols are the redundancy and overall lower performance.
Reimplementing everything from remote and wired to connectionless and association situated application correspondence, with each ringer and shriek of BGP, MPLS, multicast steering and so on would be a gigantic endeavor and potentially unmanageable in this solid across the board convention. I could envision specialty utilize situations where most extreme execution is imperative most importantly where an exceptionally basic framework might be wanted.

Answer:
public class num6 {
    public static void main(String[] args) {
        int n = 4;
        for(int i = 1; i <= n; ++i) {
            for(int j = 1; j <= i; ++j) {
                System.out.print("* ");
            }
            System.out.println();
        }
    }
}
Explanation:
This solution is implemented in Java
Two for loops are required for this (an inner nd outer for loop).
The innner and outer for loops can be seen as implementing rows and columns (so on the first 'row' i=1, so a single star is printed, on the second row, i =2, two stars are printed and so on, all on seperate lines)
