RAM, or Random Access Memory, is a kind of computer data storage, that permits the information to be read randomly without accessing the preceding bytes before that. That makes the RAM significantly quicker than other types of storage devices including DVDs or HDDs in which all the info has to be read so as to access particular information. In case you have a shared hosting account, the amount of memory which your web apps can use can't be fixed and may regularly be determined by the free memory which is available on the physical server. Using a standalone server, however, there is always a minimum amount of physical memory that will be for your use at all times and won't be allotted to other customers even if it isn't being used. That is valid with our virtual and dedicated servers.
