What is the most important reason to create a backup of your files somewhere other than your computer

1 answer:

6 0

The most important reason we should make a backup of our files on a USB or other device is in case our computer suddenly dies. If something in it goes bad and it stops working, you will have then lost everything on your computer. But, if you make a save, you can buy another computer and upload everything onto the new one.

Provide an example of a question that could NOT be answered with a binary message. Explain why this is the case, making referenc

solong [7]

This is a question with a much simpler answer given its open ended ness - a representation merely means, given binary data, we can determine what 'thing' that binary data corresponds to.

That makes the question unanswerable, because words can all be represented in binary data, and the question cannot be answered without those. Thus, all answers we can convey have a binary representation of some form (that form being the translation of the words we used to communicate the answer into binary data).

Meg[] elements = {new Lois(), new Stewie(), new Meg(), new Brian()}; for (int i =0; i

Stells [14]

Complete question is attached as snapshot.

Answer:

This will result in a compilation error.

Here's the inheritance hierarchy:

Meg -> Lois -> Brian -> Stewie

Now Meg has 2 public Fxns, a() and toString().

Lois inherits from Meg and all its public functions as well but, overrides the a() fxn of its super class.

So finally Lois has fxns a(), b() and toString().

Brian extends Lois and inherits all the above listed fxns of Lois, but overrides the b() and toString() fxns.

Stewie extends Brian and inherits all the fxns of Brian, but overrides the a() and toString() fxns.

In the Main driver fxn, we call a() and b() methods of all these classes but, the base class Meg has no b() and it is not extending any class so its not available in its scope.

This results in a compilation error.

Jlenok [28]

Answer:

I am writing Python program.

string = input("Enter a string: ")

print(string.count(' '))

Explanation:

The first statement takes input string from the user.

input() is used to read the input from the user.

The next statement uses count() function to count the number of times the specified object which is space ' ' here occurs in the string.

The print() function is used to return the number of times the space occurs in the string entered by the user.

Output:

Enter a string: How are you doing today?
