Questions and Answers

What is the main problem with computers when it comes to generating random numbers?

  • Computers cannot generate numbers at all.
  • Computers are designed to be unpredictable and follow illogical patterns.
  • Computers can only generate small random numbers.
  • Computers are designed to be predictable and follow logical patterns. (correct)

    • Why is it important for modern encryption to rely on big, properly random numbers?

  • It increases the speed of encryption and decryption processes.
  • It ensures that the encryption cannot be broken by predicting the numbers used. (correct)
  • It simplifies the encryption process for computers.
  • It reduces the amount of data transmitted over the internet.

    • What does Cloudflare primarily do as a service for websites and web services?

  • Generates truly random numbers for encryption purposes.
  • Predicts random numbers for encryption purposes.
  • Transmits data over the internet.
  • Provides free SSL encryption for websites. (correct)
