RAM, or Random Access Memory, is a kind of computer data storage, that allows the info to be read randomly without accessing the preceding bytes before that. That makes the RAM noticeably faster than other kinds of storage devices including DVDs or HDDs where all of the info must be read so as to access particular info. In case you have a shared hosting account, the amount of memory that your web applications can use may not be fixed and may commonly rely upon the free memory which is available on the physical server. With a standalone web server, however, there's always a minimum amount of physical memory that'll be readily available at all times and shall not be allotted to other clients even when it is not being used. That's valid with our virtual and dedicated hosting servers.
