One-time pad. The one-time pad (OTP) is an encryption technique that cannot be cracked, but requires the use of a one-time pre-shared key the same size as, or longer than, the message being sent. In this technique, a plaintext is paired with a random secret key (also referred to as a one-time pad). Then, each bit or character of the plaintext is encrypted by combining it with the corresponding bit or character from the pad using modular addition. If the key is truly random, at least as long as the plaintext, never reused in whole or in part, and kept completely secret, then the resulting ciphertext will be impossible to decrypt or break. It has also been proven that any cipher with the perfect secrecy property must use keys with effectively the same requirements as OTP keys. Digital versions of one-time pad ciphers have been used by nations for some critical diplomatic and military communication, but the problems of secure key distribution have made them impractical for most applications.
Answer:
Yes, if you want to be undetected.
Explanation:
It is vital to always use a command that will ensure that one's activity is undetected. This is one of the important rules of corporate organizations to keep their data and activities safe and secure. The commend provided is a useful tool for detective works especially the activities of criminals and hackers. Therefore, if the admin wants to be undetected, the command should not be used.

Explanation:
//Programmed in Java
public double avgList(int [] nums){
int I;
double sumOfNumbers = 0;
double averageOfNumbers = 0;
//Loop over to sum all elements in the list.
for(I = 0; I < nums.length; I++){
sumOfNumbers += nums[I];
}
//Calculate the average
averageOfNumbers = sumOfNumbers/ nums.length;
return averageOfNumbers;
}
Answer:
10.
Explanation:
Decimal numbering system is a number system which has ten digits. These ten digits are 0,1,2,3,4,5,6,7,8 and 9. It has signed and unsigned digits. The signed digits represents negative values of digit with the minus "-" sign written before the digit. The unsigned digits have no sign before them.
Binary numbering system has only 1 and 0 digits, while the hexadecimal number system has 16 digits.

Explanation:
In an inheritance situation, the new class that you create from an existing class is known as the derived class or child class. The class that the child class inherits from is called the parent class. Child class or derived class has access to all the public and protected fields and methods in the parent class. The child class in effect is extending the implementation of the parent class with additional functionality.
