Question 16

True or False?

Each server computer that you may connect to will be logically organized into ports . Theoretically, there are a large number of available ports. A subset of those port numbers are predefined to be used for certain standardservices. For example, if you want to connect with a public server that communicates using the HTTP protocol, you would normally connect to port 80 onthe server of interest.

Question 21

True or False?

Java provides at least two different approaches for doing network programming (and possibly more) , insofar as the web is concerned. The two approaches are associated with

  • The Connector , DatagramConnector , and ServerConnector classes
  • The URL, URLEncoder, and URLConnection classes.
