The Hypertext Transfer Protocol (HTTP) is a protocol designed for retrieving hypertext markup language documents, which are often referred to as "web pages". Groups of related webpages form what is known as a website. Today, websites are often enhanced with publicly accessable "Message Boards", "RSS feeds", and "wikis". HTTP servers are normally accessed through a client called a Browser, using the URI "http://" (or "https://" if connections are secured). If you need a Browser for an uncommon operating system, you can download it from this link. A good Browser should be able to pass the Standards Test found at this link. Not all web pages are made visible to the public, and even those can have indexing blocked through "robots.txt" files and page header meta tags. Below are links that list web pages on public HTTP servers.
