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 significantly faster than other sorts of storage devices like DVDs or HDDs where all of the information must be read so as to access certain data. When you have a shared hosting account, the amount of memory your web programs can use may not be fixed and may regularly depend upon the free memory that is available on the physical server. Using a standalone server, however, there is always a minimum amount of physical memory which shall be available at all times and will never be allotted to other clients even if it's not in use. That's valid with our virtual and dedicated hosting servers.
