RAM is an abbreviation for Random Access Memory. This is a sort of computer memory, that, unlike other storage devices including harddrives or DVDs, allows the info to be accessed directly without reading the previous content saved within it. Whenever an application is launched, it is stored inside the RAM, as it can be accessed much more quickly than if it was read from another media. With regard to the hosting service itself, additional RAM means that more web applications can operate all at once on a certain hosting server, especially if they are resource-demanding and are accessed by a large number of people all at once. Not like a shared web hosting solution in which the resources of a certain account may be flexible and often depend on what other end users consume also, a VPS includes a guaranteed amount of RAM that can be used at all times. That memory is allocated to one web server only and will not be used by other customers even if it's not being used.
Guaranteed RAM in Dedicated Servers
The amount of RAM included with every dedicated server that we supply is sufficient enough even for extremely resource-demanding web apps. The memory shall be readily available for your sites and all other software you install on the hosting server at all times, so if at some point you use only a fraction of the resources that you have, we'll never alter the hardware configuration that you have ordered. All the components are tested before the hosting server is assembled, including the RAM sticks, to make certain that you'll get a flawlessly performing web server that can guarantee the best possible overall performance for your websites. The amount of physical memory you have shall be listed with the full server configuration specifications inside your billing CP.
