RAM, or Random Access Memory, is a sort of computer data storage, which enables the info to be read randomly without accessing the preceding bytes before that. This makes the RAM a lot quicker than other types of storage devices including DVDs or HDDs in which all of the data has to be read in order to access particular info. If you have a shared hosting account, the total amount of memory which your web apps can use cannot be fixed and may sometimes depend upon the free memory which is available on the physical web server. With a standalone hosting server, however, there is always a minimum amount of physical memory that shall be at your disposal at all times and won't be allotted to other customers even when it isn't used. That's valid with our virtual and dedicated servers.
