Questions and Answers

What is the primary purpose of the Hypertext Transfer Protocol (HTTP)?

  • To interact with network-based hypertext information systems
  • To be aware of each client's purpose
  • To have predetermined sequence of application steps
  • To hide the details of how a service is implemented (correct)

    • In what way does HTTP enable flexible interaction with network-based hypertext information systems?

  • By being stateful instead of stateless
  • By being dependent on the types of resources provided
  • By having a non-self-descriptive message system
  • By sharing a generic interface and self-descriptive messages (correct)

    • How does HTTP reduce interaction complexity?

  • By being limited to defining the syntax of communication
  • By enabling general-purpose implementations in different contexts (correct)
  • By requiring servers to be aware of each client's purpose
  • By defining the protocol in terms of what occurs behind the interface
