Question 1 of 10

Computers and Technology

Mila [183]2 years ago

Answer:

D. Government and law enforcement want access to encrypted messaging apps to help fight criminals and terrorists.

Explanation:

The explanation is simple: if a messaging application has encryption implemented into its functionality, then it means one of the purposes of that application is maintaining the privacy of the end user.

If a government and the law enforcement under that government want access to encrypted messaging applications with the intention of fighting criminals and terrorists -- which is an altruistic act to maintain security in the country -- this defeats the purpose of maintaining the end user's privacy if the developer(s) of the app were to hand over that data to a government and the law enforcement under them.

This is a famous example of security vs privacy, actually.

What makes the huns a formidable force for the roman empire?
Maurinko [17]
<span>The Huns were a formidable force to fight. They were able to eat most food without problem which removes the needs for supply trains and such and encourages pillaging. Another reason is that their a cavalry based army which completely decimated roman military since the roman empire consist of flat land and they could outflank, outrun, and could whittle down an army with ease. They also are nomads which means you don't know where they're living and so you can't be on the attack which also gave an advantage. This points that the Huns are a force to be reckon with.</span>

A laptop computer has two internal signals: An unplugged signal, which is '1' if the laptop's power supply is connected, and '0'
Brums [2.3K]

Answer:

The correct usage is a NOR gate which is indicated in the explanation.

Explanation:

The truth table for the given two signals, namely

p=unplugged signal

q=low battery signal

can  form a truth table of following form

Here p has 2 states

1 if the power supply is connected

0 otherwise

Similarly q has 2 states

0 if the battery has reached almost zero state

1 otherwise

As the condition for the Hibernate Signal is given as to only activate when the battery is low and the power supply is not connected. This indicate that the value of Hibernate signal should be 1 when both p and q are 0.

Using this condition, the truth table is formed as

unplugged signal | low battery signal |  Hibernate Signal

            0               |                 0             |             1

            0               |                 1              |             0

            1                |                 0             |             0

            1                |                 1              |             0

Now the truth table of NOR is given as

a    |     b    |  a or b   |   ~(a or b)

0    |     0    |      0      |        1

0    |     1     |      1       |        0

1     |     0    |      1       |        0

1     |     1     |      1       |        0

This indicates that the both truth tables are same thus the NOR gate is to be used for this purpose.

In symmetric encryption the same key is used to encrypt and decrypt a message. in asymmetric encryption different keys are used
Brrunno [24]

A useful advantage of Asymmetric encryption over symmetric encryption is that there is no secret channel necessary for the exchange of the public key, unlike in the symmetric encryption which requires a secret channel to send the secret key.  

Another advantage of Asymmetric encryption is that is has increased security. Asymmetric uses two different keys (Public and private) for both encryption and decryption of data while symmetric uses one.

Consider this program segment: int newNum = 0, temp; int num = k; // k is some predefined integer value 0 while (num &gt; 10) {
Doss [256]

Answer:

All of these statements are true.

Explanation:

Since the while loop is reversing the integer number and leaving the highest order digit in the num and stores the reversed number in the newNum variable.

It skips one digit so if the num is in the range of [100,1000] it will result in a number between 10 and 100.

This loop can never go in infinite loop for any initial value of num because the loop will run as many times as the number of digits.

and if the value of the num is <=10 the while loop will never run and the value of newNum will be 0.
