The Debian GNU/Linux operating system is a fully-featured operating system for servers, workstations, and home desktop machines alike. It can serve up web pages, relay email, provide a database backend and file-sharing services, authenticate users, firewall and monitor networks, control appliances and power embedded devices. Debian can also act as a workstation or desktop machine, allowing users to browse the Internet, read and write emails, author documents, calculate spreadsheets, edit images, view multimedia content, play games, write software, or manage schedules, contacts and other personal information.
