A URL, or uniform resource locator, is the Internet address of a file. URLs are case sensitive. The most common syntax of a URL is:
protocol://machine[:port]/path/filename.html
where the parts of the URL are:
| protocol | The Internet protocol used to transmit the file. Examples of different protocols are shown below. |
| machine | The domain name of the server where the file is stored (e.g., www.company.com). |
| :port | The TCP port number; only required when a non-standard number is used. |
