A home page is the initial page of a website, the ‘point of entry’ to all the information stored within. It's similar to the front page of a newspaper, but a home page contains links to a selection (or, in some cases, all) of the available content.
The term 'home page' is also used to refer to the page you encounter first when connecting to the internet. This is often the main page of your search engine, but you can ‘customise’ this home page to link directly to your preferred webpage, whether that be BBC News or Digital Unite. You can even arrange to have a blank page as your home page.
