History :
Before HTTP protocol was invented the internet was just a huge network consisting of FTP servers, and internet is used as a means of file exchange. Before websites existed the first search engines ran via FTP and similar protocols. Internet acquired its actual shape only after Tim Burners-Lee had created HTTP protocol, we got the World Wide Web, and the Internet acquired its actual shape.
Search Engines Today :
Modern web searchers are divided into two main groups:
Search engines.
Directories.
Search Engines automatically 'crawl' web pages by following hyperlinks and store copies of them in an index, so that they can generate a list of resources according to user’s requests.
Directories are compiled according to categories by humans who are site owners or directory editors.
