Chapter 9: The Evolving Internet Review Questions

2. Why is it hard to determine how big the Internet is today? Give several reasons.

• The Internet is growing much too rapidly for it to be tracked.
• There is no "Internet Central" that keeps track of user activity or network connections.
• Different types of connections to the Internet results in different degrees of interactivity, thus it is difficult to know what it means to "belong to the Internet".

3. Why are TCP/IP protocols so important to the functioning of the Internet? What do they do?

• TCP/IP are practically the "language" of the Internet that allow cross-network communication for nearly any computer and network. It defines how information transfers between machines and how machines on network are defined by IP addresses or unique addresses.

4. How does the type of Internet connection influence the things you can do on the Internet?

Depending on the Internet connection, it can be much faster than others and more content streaming with higher bandwidth.

6. What do email addresses and URLs have in common?

• They both use the same domain-naming scheme.

7. Briefly describe several software tools that can be used to develop Web pages.

• Macromedia Dreamweaver, Adobe Golive, and Microsoft Frontpage are some web authoring software that make it easy to develop Web pages. Basically one lays out text and graphics in the way desired and the software will create an HTML document that looks similar to the original layout when seen on a Web browser. They are good for automating repetitive edits, apply formatting styles across pages, and check for bad links.

9. Why is file compression on the Internet important?

• This is because it makes files smaller so that they may be downloaded and played faster.

11. How does push technology differ from standard Web page delivery techniques? How is it used?

• With push technology you subscribe to the updates and information desired and the server delivers it periodically. It is used for company intranets but is increasingly used for the most trivial things such as weather updates.

12. What new services are available as a result of the commercialization of the Internet? What new problems are arising as a result of that commercialization?

• Such new services for example are: the viewing of weather patterns, book flights, buy stocks, sell cars, track deliveries, listen to radio broadcasts, conduct video conferences, organize disaster recovery programs and do countless other functions.
• Such new problems are: spam scams, get rich-quick hoaxes, online credit card thefts, email forgery, child pornography, illegal gambling, online stalking and other condemned acts.
