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 Java4620: General Information 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?

A network is a group of computers and other devices that are connected in some fashion for the purpose of exchanging data.

Go to answer 1

Question 2

True or False?

Each of the devices on the network can be thought of as a node , and each node has the same address.

Go to answer 2

Question 3

True or False?

Modern networks transfer data using a concept known as packet switching .

Go to answer 3

Question 4

True or False?

In order for two or more computers connected to a network to be able to exchange data in an orderly manner, each computer must use a different protocol.The protocol defines the rules by which they communicate.

Go to answer 4

Question 5

True or False?

The HTTP protocol defines how web browsers and servers communicate and the SMTP protocol defines how some email is transferred

Go to answer 5

Question 6

True or False?

IP is an acronym that stands for Interconnection Protocol.

Go to answer 6

Question 7

True or False?

IP is a network protocol that moves packets of data from a source to a destination. As the name implies, this is the protocol normally usedon the Internet.

Go to answer 7

Question 8

True or False?

The Transmission Control Protocol ( TCP ) was added to IP to give each end of a connection the ability to acknowledge receipt of IP packets and to request retransmission of corrupted or lost packets. Also TCP makes it possible to put the packets back together at the destination in the same orderthat they were sent.

Question 9

True or False?

TCP and IP work together to provide a reliable method of encapsulating a message into data packets, sending the packets to adestination, and reconstructing the message from the packets at the destination.

Go to answer 9

Question 10

True or False?

The User Datagram Protocol ( UDP) is even more reliable than TCP/IP in guaranteeing that a series of packets will arrive in the right order. However, UDP involves a high level of overhead and the data transfer rate may be slow.

Go to answer 10

Question 11

True or False?

Every computer attached to an IP network has a unique address, typically consisting of four bytes or 32 bits. Efforts are underway toexpand the number of possible unique addresses to a much larger number. The planned number is the number of unique addresses that can be represented with a128-bit address.
