Answer:
1. Keeping a password with user name or password is very easy word.
2. Passwords should be kept strong so that it cannot be haccked. One should use upper case letters along with lower case letters and numeric and special characters to make the password strong.
3. The businesses usually run anti viruses in case of virus attack. In case of haccker attack businesses are temporarily shut down from their routine work and alternate business plan is activated which runs the business activities incognito version.
4. High profile passwords can be leaked as it is on the computer system which can be accessed from around the world.
Explanation:
The businesses should use DRP system in order to avoid complete shut down of business operations in case of a cyber attack. The passwords should be kept strong enough so that no one can crack the password and all employees should not be given complete access to business operations and planning activities. Employees access should be restricted to their job role.
Answer:
FALSE
Explanation:
Because C1 and C2 implement the same interface, they both implement whichIsIt. The variable c is known as a polymorphic variable, meaning that it can change from being an C1 to a C2. So, the message c.whichIsIt( ); may invoke C1's whichIsIt or C2's whichIsIt. This can only be known at runtime.
Answer:
- import java.util.Scanner;
-
- public class Main {
- public static void main(String[] args) {
- int num[] = new int[51];
- Scanner input = new Scanner(System.in);
- System.out.print("Number of input: ");
- int limit = input.nextInt();
- for(int i=0; i < limit; i++){
- System.out.print("Input a number (1-50): ");
- int k = input.nextInt();
- num[k]++;
- }
- for(int j=1; j < 51; j++){
- if(num[j] > 0){
- System.out.println("Number of occurrence of " + j + ": " + num[j]);
- }
- }
- }
- }
Explanation:
The solution is written in Java.
Firstly, create an integer array with size 51. The array will have 51 items with initial value 0 each (Line 5).
Create a Scanner object and get user entry the number of input (Line 6-7).
Use the input number as the limit to control the number of the for loop iteration to repeatedly get integer input from user (Line 9-13). Whenever user input an integer, use that integer, k, as the index to address the corresponding items in the array and increment it by one (LINE 11-12).
At last, create another for loop to iterate through each item in the array and check if there is any item with value above zero (this means with occurrence at least one). If so, print the item value as number of occurrence (Line 14-17).
Answer:
The value of "x" is stored at "main memory".
Explanation:
Simply Central processing unit, input device and output device can not store the data.
