Questions and Answers

What is the primary difference between lossless and lossy compression?

  • Lossless compression is faster than lossy compression.
  • Lossless compression reduces file size without losing any data. (correct)
  • Lossy compression is more effective for text than images.
  • Lossy compression allows for perfect reproduction of data.
  • Which of the following statements best describes the purpose of TCP?

  • TCP ensures reliable delivery of packets over the internet. (correct)
  • TCP creates packets of data but does not facilitate their delivery.
  • TCP is used for sending large files without any error corrections.
  • TCP is used only for local network communications.
