So that the web server knows what page to show when only the domain is requested.
The first page can be named anything that the web server recognizes as the default page. Index.htm and default.asp are two of the most common but most web servers can be configured to show any page as the first page.
The starting page of a Website is called the home page. It is also known as the index page, since the file name for the first page of the website is index.htm or index.html.
The first page of the website is called index or homepage.
The first page of a website is called the home page. Its file name is usually the word "index" or, less commonly, "home" or "default" with an extension used on a given website (.htm, .html, .php, etc.)
Index is generally the homepage of a website. It is the main or the first page which appears.
A home page
If surfing the web and going to a website for the first time, usually the first page seen is either the homepage (sometimes called index page) or a cover page in some websites where you are directed to enter the site by clicking on an internal link which takes you to the homepage or index page. If you are searching a specific topic and find a link to a website for that topic it may take you to a page inside the site where there is info on that specific topic.

The index page
The index page is the main page of the website (also known as 'home'). It also has contents. So there is no such thing as contents page because all pages have contents. What you really meant might be "inside pages" like contacts, about me or similar subpages of the index page.
Each web server has a directory. Index htm or index html is the default page name in that directory. The main page or homepage should have the extension index htm.
In common usage, none. Technically though, a website is a group of pages. For example: WikiAnswers is a website, while each question has it's own page. Generally, when someone says 'webpage' they are referring to the index (starting page) of a website.
