Dedicated Hosting Server
Corporate websites, social networks and video sharing portals are very popular and heavy web pages that need a lot of resources to function. The more visitors a web portal is having simultaneously, the more resources will be required to tackle all the requests from the customers' browsers and to execute them. This is the reason why a dedicated web hosting server would be the optimum hosting environment for such websites.
Dedicated Server Hosting
With the dedicated server hosting solution, you lease a whole physical machine whose resources will be used only by your web sites. Just as any computer, each dedicated server has one or more central processing units functioning at a certain speed, a given amount of RAM, one or more hard disks, and so on. A dedicated web hosting server is indeed a computer with a hardware configuration meant to cope with heavy load and certain software installed on it, like a web server, PHP and MySQL software, etc., which allows the web sites accommodated on it to be visible on the World Wide Web.
VPS
Because shared shared web hosting accounts have restricted features and a dedicated server is too pricey for the majority of individuals, given hosting corporations deliver a third webspace hosting service sort - the Virtual Private Server. This web site hosting solution offers great performance at a quite low rate and is frequently the preferred option for online portals that devour lots of system resources.
Shared Hosting
As the name hints, the shared web page hosting solution is a type of service where multiple customers share the system resources of one and the same server. This goes to say that all web server ingredients such as CPU, hard disk drives, RAM, network cards and so on, are divided among the customers whose accounts are on that very same web server. This is mainly made achievable by opening different accounts for the different users and allocating certain restrictions and usage quotas for each of them. Those restrictions are fixed in order to prevent the clients from interfering with each other's accounts and, of course, to prevent the server from overloading. Usually, shared web hosting customers do not have root-level access to the hosting server's config files, which basically indicates that they cannot access anything else on the web server but their own hosting account. The web hosting features that each account may resort to are set by the web hosting vendor that possesses the hosting server and by the particular site hosting plan.
