OLEGan [10]

DES is a commonly used symmetric encryption

A) is a commonly used symmetric encryption

<u>Explanation:</u>

DES stands for Data Encryption Standard. It is a symmetric key algorithm and is used for encrypting electronic data. It was developed in 1975. DES is one of the oldest encryption standards to be used in the industry.

The algorithm takes 16 rounds of permutations in order to encrypt data. But now, with the advent of technology, as new algorithms have been designed and put in use, DES is less preferable.

In the process of key generation, some keys generated sometimes turn out to be weak and hence are prone to attacks. If not for the weak keys generation, DES works perfectly fine and is an effective algorithm to encrypt data.

How to write the algorithm to calculate the square of five numbers
ioda

Answer:

1. A = 7 and B = 12 here...

2. A^2 = 49 thus final answer will have 9 at units place and 4 is carried to add later.

3. Given number multiplied by 'B' => 127*12 = 1524

4. A*B => 12*7 = 84

5. 1524+84 = 1608 ..... ( step 3 + step 4 )

6. 1608+4 =1612 .... (4 is carried as stated in step 2)

7. Now, 16129 is the answer... (From step 2 and 6)

Explanation:

Divide the number in two parts with one part containing only the number at unit's place say part 'A', and other part say 'B', containing the remaining number.

Now square the number at unit's place. The square will be one of these; {0,1,4,9,16,25,36,49,64,81}. The unit's place digit in this square is the unit's place digit in actual final answer.Write it in the answer. If the square of digit at unit's place is a two digit no like from 16 to 81 in above set; write only the digit at unit's place from this square in the final answer and carry the remaining digit.

Multiply the actual number to be squared by part 'B'(the remaining part than the number at unit's place as described in step 1 ).

Multiply the parts 'A' and 'B'.

Add results of step 3 with results of step 4.

Add the carried digit from step 2 to the sum in prior step, that is step 5.

Now write this sum before the number we wrote at unit's place of final answer in step 2.

This number we now obtain from step 7, is the square of our number.

Setler [38]

In order to make the program recognize the clicking of a button, the engineer should add an event listener to the JavaScript code.

An event is considered to be a vital part of JavaScript because a web page responds according to the event that occurred. Some events are generated by APIs and some are user-generated events. For example, clicking or moving the mouse button and pressing a key on the keyboard are user generated events.

In order to handle the user-generated events in JavaScript,  an event listener is used. An event listener is a function or procedure in a JavaScript program that waits for an event to occur; such as pressing a key on the keyboard or clicking the button. Therefore based on the scenario given in the question statement, the engineer should use an event listener to his JavaScript code so that the code can recognize the click of the button.
