Part Six: Advanced Concepts and Conclusion

It is out of the scope of this Web site to explain all aspects of how the Internet works. Some important concepts that shape the use of the Internet include:

  • Firewalls - These are configurations on gateways and routers than prevent service requests from entering a network. They are designed to protect networks from intruders. More information can be found at HowStuffWorks.Com
  • IP Telephony - This new technology allows for the use of telephones via TCP/IP. Since there are now long-distance or usage charges with TCP/IP, this will dramatically lower the cost of telephones. For more information on IP Telephony, see HowStuffWorks.Com.
There are thousands of other technologies associated with the Internet, and a good place to find further information is the computer section of your local bookstore or library.

To gain a solid knowledge of the Internet and it's technologies, one can seek a Cisco CCNA Certification.

It is my hope that this information was useful to you. If you have any questions, comments, or suggestions about this Web site (including spelling and grammar), please send them to eric@chernoff.org.
