Operating System (OS): The most important program that runs on a computer is operating system. OS is the term that acts as an interface between the hardware and the user. OS does basic operations such as getting input from the keyboard, displaying output in the monitor and monitoring the files.

The responsibilities of OS are bound to get higher when it comes to security, because it provides the access rights for users.

Question 2 (10 Points): String vs. StringBuilder Create a Question2.java file and finish the following tasks: Task 1. a) Create a 1D array of integers to store 50 integers. b) Store values from 0 to 49 in the array you just created. c) Create a new String Object using no-arg constructor. d) Using for loop to add the array elements one by one to the String (one per loop iteration) Hint: to append an element to a String, use the + operator. e) Output the String on the console. Record and display a run-time it took to append all integers to the String (record run-time of 1.d.)). Please submit a screenshot. The screenshot should match the following example: 012345678910111213141516171819202122232425262728293031323334353637383940414243444546474849 it took 196708 nanoseconds to append 50 integers to the String.| Hint: You can use the following statements to record run-time. long begin, end, time; // we will measure time it took begin = System.nanoTime(); //we measure in nanoseconds. // put…
