Linux: The ``Free'' Choice

• A completely free reimplementation of the POSIX specification, with SYSV and BSD extensions (which means it looks like Unix, but does not come from the same source code base)
• Runs on 386/486/Pentium machines with ISA, EISA, PCI and VLB buses
• Also on Motorola 680x0 platforms, DEC's Alpha CPU, Sun SPARCs
• Linux is being actively ported to the PowerPC architecture, including PowerMac (Nubus and PCI), Motorola, IBM, and Be machines
• current stable version is 2.0.31
• A boon to many organzations (IIT Bombay!)
