INTERNET WEBB ADDRESSES,
URL, or WHAT……?
There being so much information on the NET, every entry has a specific address by which they can be identified. The technical jargon for a WEB ADDRESS is Universal Resource Locator. URL for short. URLs point to a service or a file on the Net, thereby identifying the resources, specifying its service, as well as its precise location. The URL is a unique identifier that "SURFERS" use to look for a particular WEBSITE. It is also the launching mechanism for opening the website in question.
When your browser has connected to the website you requested via it's URL, it transfers and interprets the information. Finally it (The browser) displays the relevant information for your viewing. If you look at the bottom of your screen you can see the progress "Opening page http//www.whatever" and finally "Done" Sometimes it takes a while if you are opening a page with lots of graphics. (Depending on your PC's ability, not to mention your ISP. ADSL and CABLE are far superior to Dial-Up connections.) When downloading graphics you'll see how many items are remaining before "Done" appears. http stands for Hypertext transfer protocol. This the language for online documents. www is short for the World Wide Web. "Whatever" is the domain name of the website or entity. Com indicates the type of business, com meaning commercial. There is also government, education, organisation, etc. au designates the country of origin, exception being the USA. Bigpond is also without the telltale au. http://www.crayne.com/country.html will give you all the abbreviations used by different countries. http://www.norid.no/domreg.html takes you to the site of domain names registered around the world.
Web addresses and URLs must be always opened with correct Internet applications. URLs with http:// are to be opened with a browser. ftp:// can sometimes be opened with your browser. It will be displayed however as an Index Directory. File Transfer Protocol (FTP) applications should do the job. Everything must be the same when typing in URLs. Take notice of Capital Letters, dots, (URLs never end with these) tildes (~) hyphens (-) underscores ( _ ) slashes (/) backslashes (\). Even question marks (?) have a specific meaning and place.
