Linux is commonly used for a wide range of technical and commercial reasons today. Linux runs on a tremendous range of supported architectures,
processors, buses, and devices, and combines the power of inherent multi-tasking with the attractive notion of an open, royalty-free operating system.
At the high and medium ends, Linux systems support enterprise infrastructure such as file, mail, and web servers, and business-unit infrastructure
such as firewalls, VPN servers, routers, and gateways. In its smallest incarnations, Linux is commonly used in embedded systems such as process
control systems, PDAs, home gateways, and set-top boxes.
