Linux is among the most popular Operating Systems for web servers. There are quite a few different distributions that use exactly the same core, but the vast majority have a couple of things in common - they're free to use, which decreases the total cost of the hosting service because license fees will not be included in what you'll have to pay; they are quite simple to manage; and last, but not least, they are considerably more secure as compared with competitor OSs, because random files, specifically virus-infected ones, just cannot be executed on the web server. This way, you can enjoy a reliable service and spend the time developing and advertising your websites, not worrying about basic safety problems. A lot of Linux-based machines use the Apache web server to handle the HTTP traffic, due to the fact that this software system is really fast and is also easy to maintain and individualize as per the needs of the web hosting provider. A Linux server with Apache is the ideal software environment for your sites and it's not at all a coincidence that a lot of popular script-driven applications out there require LAMP, that refers to Linux, Apache, MySQL and PHP.
