what are features of linux,
what are the functions of linux

First, no idea what you're asking, or what the context of your question is. Second, what do you think anyone will be able to tell you? That's like asking "What are the features of Windows, and what can Windows be used for?". It's a computer OS...it can be used for anything from text-based number crunching, to 3D games. Features go from stand-alone, to massively clustered.
