​which type of cryptography provides the most security?

Computers and Technology
1 answer:
Doss [256]3 years ago
4 0

Answer B: Asymmetric cryptography, because the receiver has its own decryption key and cannot create encrypted messages, because he doesn't have the encryption key.

About the other answers:

A: Private keys are always involved, there has to be some secret to do encryption, so this answer doesn't say very much.

C: Digital signatures can be used to verify/prove some data comes from some person (the signer) in an unaltered way. It is not about encryption, so is not about the security of your message. You use it in combination with encryption.

D: Like A, this doesn't say very much. Shared secret keys (symmetric keys) can be used for encryption, but they are less secure since the keys have to exist in more than one place (sender and receiver).

Which technology can allow a single ground-based telescope to achieve images as sharp as those from the Hubble Space Telescope?
Ganezh [65]

Answer:

The correct answer to the following question will be "Adaptive Optics".

Explanation:

  • AO (Adaptive Optics) is a technique used to enhance optical system performance by reducing the impact of incoming gravitational wave distortions by compressing a mirror to compensate for the distortion.
  • It operates by calculating and compensating for defects in a wave-front with a system that corrects these errors as a deformable mirror or even a liquid crystal collection.
  • It is a technique that can make it possible for a single ground-based telescope to get images as clear as that of the Hubble Space Telescope.
  • Certain methods can achieve power resolution that exceeds the limit set by atmospheric distortion, for example, Aperture synthesis, Lucky imaging, and Speckle imaging.

Therefore, Adaptive Optics is the right answer.

Kim is writing a sql query that will pull a list of customers with outstanding orders and the sales rep for each order. What sho
Step2247 [10]

What the phrase should say in Kim's SQL Query is;  WHERE Customer = Sales Rep

<h3>What is SQL Query?</h3>

Structured Query Language (SQL) is defined as a standardized programming language that is used to manage relational databases and perform various operations on the data in them.

Now in SQL Query, when one SQL query is embedded in another SQL query to simulate a join, the second SQL query is embedded in the "WHERE" of the first query.

Since the query will pull a list of customers with outstanding orders and the sales rep for each order. Then, the where phrase will be;

WHERE Customer = Sales Rep

Grace [21]

COMPLETE QUESTION

I. public class Test {

public static void main(String[] args){

System.out.println("Welcome to Java!");

}

}

II. public class Test { public static void main(String[] args) {System.out.println("Welcome to Java!");}}

Answer:

Both codes will compile and run and display Welcome to Java, but the code in II has a better style than I

Explanation:

When written codes, paying attention to proper coding styles and efficient memory management enables us to create programs that are highly efficient, coding styles refer to proper indentions and avoiding too lenghty lines of code (as is in code I), adding approprite comments etc.

Luminaires for fixed lighting installed in Class II, Division 2 locations shall be protected from physical damage by a suitable
ser-zykov [4K]

Given what we know, the protection for fixed lightings like the ones described in the question is by way of a guard or by location.

<h3>Why is protection necessary?</h3>

Luminaires, as with all lighting solutions, can be dangerous if proper safety precautions are not taken. The precautions, in this case, include a safe installation location or the use of a guard to prevent damage to the lighting and subsequently to any nearby occupants of the location.

Therefore, we can confirm that Luminaires for fixed lighting installed in Class II, Division 2 locations shall be protected from physical damage by a suitable guard or by a safe location.
