Linux is among the frequently used OSs for servers. There are many different distributions which use the same core, but the vast majority have a couple of things in common - they're free to use, which cuts down the overall cost of the web hosting service as license fees won't be included in what you will have to pay; they are quite simple to manage; and last, but not least, they are considerably more secure compared with competitor Operating Systems, as random files, particularly virus-infected ones, just cannot be executed on the web server. That way, you can enjoy a secure service and spend the time building and advertising your websites, not bothering with basic safety issues. Many Linux-based machines use the Apache web server to handle the HTTP traffic, because this piece of software is very quick and is also simple to maintain and modify depending on the needs of the web hosting provider. A Linux web server with Apache is the perfect software environment for your sites and it's not a coincidence that many popular script-driven apps nowadays require LAMP, which stands for Linux, Apache, MySQL and PHP.
