RAM, or Random Access Memory, is a form of computer data storage, that permits the data to be read randomly without accessing the preceding bytes before that. That makes the RAM substantially faster than other sorts of storage devices like DVDs or HDDs where all of the data has to be read so as to access particular information. If you have a shared hosting account, the total amount of memory which your web programs can use may not be fixed and may often depend on the free memory that's available on the physical web server. With a standalone server, however, there's always a minimum amount of physical memory that will be at your disposal at all times and shall not be allotted to other customers even when it's not used. That's valid with our virtual and dedicated servers.
