A web server strictly speaking would be a server that hosts web sites. The choice you have least expensive first:
Shared Hosting - a share on a web server, no fixed CPU, Disk Space, Bandwidth
VPS - A slice of a server that has defined parameters for CPU etc
Dedicated - A server all to yourself
Dedicated servers are more secure than shared servers. On shared servers anyone is able to access the server, whereas with dedicated servers, only those who are authorized can access the server.

Unix servers can be less expensive than Windows servers because you are not paying for the server software. Unix is also less likely to get viruses or be hacked, so the money you put into time fixing the server also is a consideration. That said, if you are using a hosting service, they may make cost decisions based on what they are more familiar with.
VPS hosting is one of the most popular hosting services you can choose for your website. It uses virtualization technology to provide you with dedicated (private) resources on a server with multiple users. It’s a more secure and stable solution than shared hosting where you don’t get a dedicated server space.VPS hosting is usually chosen by website owners who have medium-level traffic that exceeds the limits of shared hosting plans but still don’t need the resources of a dedicated server.
