Before the Web and the graphics-based Web browser, the Internet was accessed from Unix terminals by academicians and scientists using command-driven Unix utilities. These utilities are still used; however, today, they reside in Windows, Mac and Linux machines as well. For example, an FTP program allows files to be uploaded and downloaded, and the Archie utility provides listings of these files. Telnet is a terminal emulation program that lets you log onto a computer on the Internet and run a program. Gopher provides hierarchical menus describing Internet files (not just file names), and Veronica lets you search Gopher sites. See FTP, Archie, Telnet, Gopher and Veronica.
