RAM, or Random Access Memory, is a kind of computer data storage, which enables the info to be read randomly without accessing the preceding bytes before that. That makes the RAM considerably quicker than other types of storage devices like DVDs or HDDs where all of the data has to be read in order to access specific information. When you have a shared hosting account, the exact amount of memory that your web apps can use may not be fixed and may often rely upon the free memory which is available on the physical web server. When using a standalone hosting server, however, there's always a minimum amount of physical memory that will be available at all times and will not be assigned to other customers even if it isn't in use. This is valid with our virtual and dedicated web servers.
