RAM, or Random Access Memory, is a kind of computer data storage, that permits the info to be read randomly without accessing the preceding bytes before that. This makes the RAM considerably faster than other sorts of storage devices such as DVDs or HDDs in which all of the info needs to be read in order to access particular data. If you have a shared hosting account, the total amount of memory which your web programs can use cannot be fixed and may sometimes depend upon the free memory that's available on the physical machine. With a standalone hosting server, however, there's always a minimum amount of physical memory which will be available at all times and will not be allocated to other clients even when it is not in use. That's valid with our virtual and dedicated web servers.
