Questions and Answers

In the OSI model, which layers are combined into one Application Layer in the TCP/IP model?

  • Layers 1, 2, and 3
  • Layers 2, 3, and 4
  • Layers 3, 4, and 5
  • Layers 5, 6, and 7 (correct)

    • What responsibility is not taken by TCP/IP, leaving it to the underlying transport layer?

  • Error recovery
  • Sequencing and acknowledgment functions (correct)
  • Data encapsulation
  • Flow control

    • What is a key difference between TCP/IP and OSI regarding their design purpose?

  • OSI is designed for specific communication problems
  • TCP/IP is more comprehensive than OSI
  • TCP/IP is a generic communication model
