Preface

This module is one in a collection of modules designed for teaching INEW 2338 Advanced Java (Web) at Austin Community College in Austin, TX.

This module contains review questions and answers keyed to the module titled Java4660: Sockets in the Network Programming sub-collection.

Once you study that module, you should be able to answer the review questions in this module.

The questions and the answers in this module are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.

Questions

Question 1

True or False?

Sockets in Java come in at least three varieties that are implemented by the following Java classes

  • Connector
  • DatagramConnector
  • ServerConnector

Go to answer 1

Question 2

True or False?

The Socket and DatagramSocket classes represent TCP and UDP communications respectively.

Go to answer 2

Question 3

True or False?

Generally, the ServerSocket class is used to implement both clients and servers, while the Socket and DatagramSocket classes are only used to implement servers

Go to answer 3

Question 4

True or False?

Socket programming provides a low-level mechanism by which you can connect two computers for the exchange of data.

Go to answer 4

Question 5

True or False?

Socket programming makes it possible for you to cause data to flow in a full-duplex mode between a client and a server . This data flow can be viewed in almost exactly the same way that we view data flow to and froma disk: as a stream of bytes.
