You can imagine the internet as a collection of many pages, which contain text, images, videos,etc.It's like a huge book where the pages, instead of being in a consequential order, are connected through "links".

If you want to find a website in the internet you can write its address in the address bar, just under "write address", and the click on "go".

If you need the page which has as address, for instance, www.eldy.org,  just write it in the address white area and click on the "go" button

The address of a website is usually begins with "www", goes on with some text and finishes with a point and two or three letters. E.g. www.text.com
