How to consult a web site - Web address structure (URL)
If we want to visit a web site we must know its address.
Web page addresses have the same structure.
To make it easier, a web address can be seen as a home address or a telephone number. It addresses only one web page on the net (two pages with the same URL cannot exist).
This is an example:
this prefix identifies the net name ( "www", which means World Wide Web, a system of interlinked, hypertext documents accessed via the Internet)
this is called "domain name", and it is name of the web sites I want to visit (for ex. google, amazon, etc.)
this ends the domain name with "top-level domain" (called also TLD) which lists different territory code web sites (for example countries: .it stands for Italy) or organisational (for example .eu is the European Union). After you have used them a while, they become more familiar and help to understand the origins of the information you are reading.
the final part (which follows the symbol slash "/") is the "web page name". It can contain several names (with a slash "/" between them) due to its position in the server archive (for example this page "/geengee/index.jsp?idPagina=51"). When this part is not well specified, the browser loads the first part of URL’s website Home Page.
Web addresses are called URLs (Uniform Resource Locator).
EXAMPLES OF WEB ADDRESSES
A website is identified by its address which allows the browser select the search engine which has that page we are looking for among the pages connected on internet all over the world.
It is extremely important to pay careful attention to how you write the address: if you make a mistake, the wrong one will be displayed or will be not found.
IMPORTANT: no spaces between the web address, for example:
Below you can see some examples of URLs where the basic structure is always the same. Some have the prefix "http://" which is a communication protocol used to transfer or convey information (if you don’t type it, the computer adds it automatically):
- www.google.co.uk
- http://plasma.nationalgeographic.com/mapmachine/index.html
- http://www.uk.vespa.com/en_UK/
- www.geengee.eu
