A home page (or homepage) is the main web page of a website.
The term also refers to one or more pages always shown in a web browser when the application starts up. In this case, it is also known as the start page.
The word "home" comes from the use of the Home key on a keyboard to return to the start page at any time. (Home was a standard key long before the Web existed.) Many browsers also provide a button in the shape of a house for this.
