RAM is an abbreviation for Random Access Memory. This is a sort of computer memory, that, in contrast to other storage devices like harddrives or DVDs, allows the info to be accessed directly without reading the previous content stored within it. Whenever an application is started, it is stored inside the RAM, due to the fact that it may be accessed much faster than if it was read from another media. In terms of the website hosting service itself, more RAM means that more web apps can operate concurrently on a particular hosting server, especially if they are resource-demanding and are accessed by a great number of of people at the same time. Different from a shared web hosting package in which the resources of a given account could be flexible and frequently depend on what other end users consume also, a VPS offers a guaranteed amount of RAM which you can use at all times. That memory is allotted to one web server only and will not be used by other customers even in case it's not used.
