Explanation:
If a device is putting data into the computer in the form of text, sound, images, button presses etc. then it is an input device, if the device is outputting things from the computer such as sound, movement, printing, images etc., then it is an output device. ... Therefore it is an input device.
Answer:
- public class Main {
-
- public static void main (String [] args) {
-
- for(int i = 2; i < 10000; i++){
- if(isPrime1(i)){
- System.out.print(i + " ");
- }
- }
-
- System.out.println();
-
- for(int i = 2; i < 10000; i++){
- if(isPrime2(i)){
- System.out.print(i + " ");
- }
- }
- }

Explanation:
Firstly, create the first version of method to identify a prime number, isPrime1. This version set the limit of the for loop as n/2. The for loop will iterate through the number from 2 till input n / 2 and check if n is divisible by current value of i. If so, return false to show this is not a prime number (Line 22 - 26). Otherwise it return true to indicate this is a prime number.
In the main program, we call the isPrime1 method by passing the i-index value as an argument within a for-loop that will iterate through the number 2 - 10000 (exclusive). If the method return true, print the current i value). (Line 5 - 9)
The most direct way to ensure all the prime numbers below 10000 are found, is to check the prime status from number 2 - 9999 which is amount to 9998 of numbers.
Next we create a second version of method to check prime, isPrime2 (Line 31 - 40). This version differs from the first version by only changing the for loop condition to i <= square root of n (Line 33). In the main program, we create another for loop and repeatedly call the second version of method (Line 13 - 17). We also get the same output as in the previous version.
Answer: This can be explained s follows :-
Explanation: The approach in which services available in the network are used by the applications is called service oriented architecture. In such structure a business function is provided by each service that is independent of other services.
Object oriented programming is a programming paradigm. OOP can be used outside of that architecture or it can be apart of SOA as well .
Answer:
OphCrack LiveCD.
Explanation:
The user examines that server of a client, as well as requires complete control of such a system. To avoid recognizing its invasion by certain security programs, he wants to select a LiveCD which can break Operating System's credentials, and he would have been using OphCrack LiveCD because it used to crack the credential of the Windows user.
So, the following are the reason by which the answer is correct according to the scenario.
