Linux is amongst the frequently used OSs for servers. There are quite a few different distributions that use the exact same core, but the vast majority have a number of things in common - they are totally free to use, which minimizes the overall cost of the website hosting service due to the fact that license fees won't be included in what you need to pay; they're very easy to maintain; and last, but not least, they are far more secure as compared with competitor Operating Systems, because random files, especially virus-infected ones, can't be executed on the web server. Thus, you are able to enjoy a reliable service and spend the time developing and promoting your websites, not bothering with basic safety issues. A lot of Linux-based machines use the Apache server to handle the HTTP traffic, as this piece of software is really fast and is also simple to maintain and individualize as per the needs of the website hosting provider. A Linux server with Apache is the best software environment for your sites and it's not at all a coincidence that numerous popular script-driven applications nowadays require LAMP, that refers to Linux, Apache, MySQL and PHP.
