A webpage is a document that is displayed on the internet, typically viewed using a web browser. It is written in a markup language called HTML (Hypertext Markup Language) and can include text, images, videos, and links to other webpages. Each webpage has a unique address known as a URL (Uniform Resource Locator), which allows users to access it easily. Webpages are part of a larger collection called a website, which is a group of related webpages hosted on a server. Websites can serve various purposes, such as providing information, selling products, or offering services. Users navigate between different webpages using hyperlinks, which connect them to other content on the internet.
