The protocol portion of the URL specifies the Internet protocol used to access network resources. Most common is the HTTP protocol, which is used to access Web pages, but other Internet protocols are also supported. Table 6.1 lists many of these protocols. This lesson focuses on the HTTP protocol because it is the most common, but you do need to know how to specify the use of other Internet services in a URL. The next two lessons offer detailed information on other Internet services.
The protocol portion of our sample URL is shown in boldface type:
http://www.comptia.org:80/certification/inetplus/faqs.htm
Note: When you're typing Web addresses, you can usually omit the "http://" because Web browsers accept this as the default.
