Linux (pronounced "lynn-icks") is an open-source operating system, which runs on more hardware platforms than any other operating system. Linux runs on x86, Alpha, Sparc, Amiga, Macintosh, and some other less known hardware platforms. In the last few years, Linux has proven itself to be the most stable, versatile and scalable network operating system. It is most
  suitable for computer networking in small office/home office (SOHO) environments . No other operating systems can match the incredible price/performance of Linux. It is free!

  Linux can provide file services for every file system currently in use, including FAT, VFAT (Win95/98), NTFS, NFS, Macintosh file system, and others. It can be used as a Web server, DNS server, DHCP server, print server, FTP server, mail server, remote access server and more. It can serve Windows 95/98 clients, NetWare clients, Macintosh clients, and UNIX clients. Any mix of clients can coexist under Linux.
