A Search Engine is a website that allows you to search the Internet via the World Wide Web. By typing a key word into a search engine, the engine will show as many articles that contain the key word(s) that you typed in.
- Some examples of search engines are google, Yahoo! Search, and Ask.com.
The very first tool used for searching on the Internet was Archie .
The name stands for "archive" without the "v". It was created in 1990 by Alan Emtage , a student at McGill University in Montreal. The program downloaded the directory listings of all the files located on public anonymous FTP (File Transfer Protocol) sites, creating a searchable database of filenames, but Archie could not search by file contents.
While Archie indexed computer files, Gopher indexed plain text documents. Gopher was created in 1991 by Mark McCahill at the University of Minnesota: Gopher was named after the school's Minnesota Golden Gophers mascot. Because these were text files, most of the Gopher sites became websites after the creation of the World Wide Web.
Two other programs,Veronica and Jughead, searched the files stored in Gopher index systems. Veronica (Very Easy Rodent-Oriented Net-wide Index to Computerized Archives) provided a keyword search of most Gopher menu titles in the entire Gopher listings. Jughead (Jonzy's Universal Gopher Hierarchy Excavation And Display) was a tool for obtaining menu information from various Gopher servers.
