RAM, or Random Access Memory, is a sort of computer data storage, that enables the information to be read randomly without accessing the preceding bytes before that. This makes the RAM noticeably faster than other sorts of storage devices such as DVDs or HDDs where all of the information needs to be read so as to access specific data. When you have a shared hosting account, the amount of memory which your web apps can use may not be fixed and may regularly depend upon the free memory that's available on the physical machine. With a standalone server, however, there is always a minimum amount of physical memory which will be readily available at all times and will not be assigned to other clients even when it isn't being used. This is valid with our virtual and dedicated web servers.
