RAM is an abbreviation for Random Access Memory. This is a type of computer memory, that, different from other storage devices such as harddrives or DVDs, enables the info to be accessed directly without reading the previous content located within it. Every time a program is started, it's stored inside the RAM, because it may be accessed much more quickly than if it was read from another media. In terms of the website hosting service itself, additional RAM means that more web applications can run at the same time on a given server, especially if they're resource-demanding and are accessed by a significant number of people at the same time. Unlike a shared web hosting package where the system resources of a certain account could be flexible and often depend on what other end users consume also, a VPS provides a guaranteed amount of RAM which you can use always. That memory is allocated to one hosting server only and will not be used by other customers even if it's not used.
Guaranteed RAM in Dedicated Servers
The amount of RAM that comes with each and every dedicated server that we provide is big enough even for very resource-demanding web apps. The memory shall be readily available for your sites and every other software you install on the web server at all times, so even if at some point you use only a fraction of the system resources you have, we shall never alter the hardware configuration you have ordered. All the parts are subjected to testing before the server is built, including the RAM sticks, to make sure that you'll get a flawlessly working machine that will guarantee the best possible performance for your Internet sites. The amount of physical memory you have will be listed along with the full web server configuration specifications in your billing CP.
