Linux is one of the most popular OSs for servers. There are quite a few different distributions that use the exact same core, but the majority have several things in common - they are absolutely free to use, which minimizes the total cost of the web hosting service as license fees shall not be included in what you'll have to pay; they are very easy to manage; and last, but not least, they're way more protected in comparison with competitor OSs, as random files, specifically virus-infected ones, can't be executed on the web server. In this way, you are able to enjoy a protected service and spend the time developing and promoting your Internet sites, not worrying about security problems. A lot of Linux-based machines use the Apache server to handle the HTTP traffic, as this software is really fast and is also easy to maintain and individualize as per the needs of the web hosting provider. A Linux web server with Apache is the ideal software environment for your Internet sites and it isn't a coincidence that a lot of popular script-driven applications on the market require LAMP, which stands for Linux, Apache, MySQL and PHP.
