Understanding What a Website Is
A web page is a document available on the Internet that you can view in your browser. It can include pictures, videos, animations, and interactive elements, and if it’s too long to fit in the screen, you can scroll it in your browser.
You can move between web pages by clicking links, which create a path from one web page to another. On a screen, a link might be just a few words or it might be a picture. A web page can include a link to any other web page on the Internet, irrespective of who owns it.
A website is a collection of related web pages, usually owned by the same person and usually having a consistent design.
To make a website available over the Internet, all its pages, images, and other content must be stored (or hosted) on a server, a computer that makes files available for others to download over the Internet. You can develop and test your website on your Raspberry Pi without a server — you only need the server when you are ready to share your website with the world on the Internet.
