RAM, or Random Access Memory, is a sort of computer data storage, that enables the data to be read randomly without accessing the preceding bytes before that. That makes the RAM substantially quicker than other sorts of storage devices including DVDs or HDDs in which all of the data has to be read to be able to access certain information. When you have a shared hosting account, the exact amount of memory which your web apps can use can't be fixed and may sometimes depend on the free memory that is available on the physical web server. With a standalone web server, however, there's always a minimum amount of physical memory that'll be at your disposal at all times and will not be assigned to other clients even when it isn't in use. That is valid with our virtual and dedicated servers.
