(40,416 posts)Linux is an actual operating system, a set of programs which form a kernel that bridges the gap between hardware and software. The main difference between Linux and Windows is that Linux does that task without specifying any user interface characteristics, whereas Windows puts those very characteristics into the kernel.
I know that this a difference in philosophy, but it is also why Linux is used as the base of many Internet platforms, as well as nearly all the supercomputers, and Windows is not. It is also why Windows is so susceptible to viruses when Linux is not.
When you mix user space with system space, nothing good will happen. That is something Windows has always done, and Linux (and all the Unices) have almost never done. It's what makes my Linux systems secure and what makes people's Windows systems insecure.
I have never had to run virus protection on any of my Linux boxes, which have included many Internet servers.
Windows sucks. It is full of security holes which are inherent in its flawed design and its marketing.
