RAM, or Random Access Memory, is a form of computer data storage, that allows the information to be read randomly without accessing the preceding bytes before that. That makes the RAM considerably faster than other sorts of storage devices like DVDs or HDDs in which all the info must be read in order to access particular information. When you have a shared hosting account, the exact amount of memory which your web apps can use can't be fixed and may frequently depend upon the free memory which is available on the physical server. Using a standalone hosting server, however, there is always a minimum amount of physical memory which will be at your disposal at all times and will never be allocated to other customers even if it isn't being used. That is valid with our virtual and dedicated web servers.
