Understanding Web Addresses
The information contained in a URL gives you the ability to hop from one web page to another with just a click. When you type a URL into your browser or click a hypertext link, your browser sends a request to a remote computer, called a web server, to download one or more files. Every URL is unique, identifying one specific file.
What does a typical URL look like? Here are a few examples:
The home page of Learn the Net.
The Facebook page for Learn the Net.
A directory of files at MIT available for downloading.
A newsgroup on rose gardening.
A blog about soccer from the Reuters news service
The first part of a URL (before the two slashes) tells you the type of resource or method of access at that address. For example:
- http - a hypertext document or directory
- ftp - a file available for downloading or a directory of these files
- news - a newsgroup
- file - a file located on a local drive of your computer
The second part is typically the address of the computer where the data or service is located. Additional parts may specify the name of a file, the port to connect to, or the text to search for in a database.
