That statement is true
in excel, you could enter point mode by pressing any keyboard navigation such as page down, page up, or the arrow keys or by clicking any cells in the worksheet
This mode will select a cell or range as formula operand
Answer: C. File encryption
Explanation: To ensure security and privacy of files and its content, encrypting the file may be an option. File encryption refers to a process of ensuring the security and privacy of individual files so as to prevent unauthorized access to the content. File encryption works by setting up a security key which will be requested or needed when the file is being clicked such that only users or individuals with the authorized pass code or password can open and read its content or modify the file, this is called file decryption.
Answer:
// A optimized school method based C++ program to check
// if a number is composite.
#include <bits/stdc++.h>
using namespace std;
bool isComposite(int n)
{
// Corner cases
if (n <= 1) return false;
if (n <= 3) return false;
// This is checked so that we can skip
// middle five numbers in below loop
if (n%2 == 0 || n%3 == 0) return true;
for (int i=5; i*i<=n; i=i+6)
if (n%i == 0 || n%(i+2) == 0)
return true;
return false;
}
// Driver Program to test above function
int main()
{
isComposite(11)? cout << " true\n": cout << " false\n";
isComposite(15)? cout << " true\n": cout << " false\n";
return 0;
}
Explanation:
Answer:
Option (b) is the correct and suitable answer for the above question.
Explanation:
The printer is a hardware which is used to convert the soft copy of an information to a printed copy (Hard copy) of information.
To use printer hardware a computer system needs a printer driver which is used to do the conversion from soft copy to a hard copy. Hardware printer uses only for the purpose to print the copy.
The option b says that the printer driver is used to convert the document into the form of that document which the printer can understand easily. It means conversion from soft copy to hard copy. Hence it is the right option.
The reason behind the other option which is not valid because--
Option a says that the printer driver is a code but it is a software.
Option c says that the printer driver is an interface but it is a software.
Option d says that the printer driver is a cache but it is a software.
