RAM, or Random Access Memory, is a form of computer data storage, that allows the info to be read randomly without accessing the preceding bytes before that. That makes the RAM noticeably quicker than other sorts of storage devices including DVDs or HDDs in which all of the information must be read in order to access specific info. In case you have a shared hosting account, the amount of memory your web apps can use can't be fixed and may commonly depend upon the free memory which is available on the physical web server. With a standalone hosting server, however, there's always a minimum amount of physical memory that will be available at all times and will never be allocated to other customers even when it is not being used. That is valid with our virtual and dedicated servers.
