Thus is true
Encryption helps to keep data virtually safe
Answer:
Operating system is the software that is used to control different hardware of computers and handle scheduled tasks.
It also handles the interrupts from some external devices, or from some software. The interrupts are handled through Interrupt service routine. When some external event occurs the following steps has been taken by OS to perform the operation
- In first step, an external event has been occurred, and request to the cpu to perform operation.
- This request invoke ISR (Interrupt service routine), to perform the operation.
- The interrupts are stored in stack on the priority basis.
- The CPU performs the operation on Interrupt as per request of ISR.
- After Completing operation, CPU return to its initial task.
Answer:
Windows key,capslock key for verify connectivity
Explanation:
Sandy's can verify whether her keyboard is working or not by pressing the windows key. Caps Lock and Num lock key will turn on the light on keyboard and she shall see whether her keyboard is functioning or not. This method is being used everywhere to verify the keyboard connectivity.The light function can also be checked by using Caps Lock or Num lock key as well. Some keyboard offers the in built light, which can be turned on by pressing Alt+Space bar.
Answer:
#include <iostream>//including libraries
using namespace std;
int main()
{
int arr[6] = { 0,1,2,3,4,5 };//make sure size of arr is 1 less than secArr
int secArr[7];//second array (1 element bigger)
for (int i = 0;i < 6;i++)//looping through each element (6 times)
{
secArr[i + 1] = arr[i];//transferring elements to second array and shifting by 1 cell
cout << secArr[i + 1] << endl;//printing elements of second array
}
return 0;//terminating program
}
Explanation:
The array size can range from any number. just make sure to keep arr one less than secArr. This is because we need the room for the extra element. This task is to help you understand how array work and how to parse through them using loops. For loops are the best for this task because even if you think intuitively, they work for as long as there are items in the array. and you can define the size yourself.
