RAM, or Random Access Memory, is a form of computer data storage, that permits the information to be read randomly without accessing the preceding bytes before that. This makes the RAM substantially quicker than other kinds of storage devices including DVDs or HDDs where all of the data needs to be read so as to access particular information. When you have a shared hosting account, the total amount of memory your web applications can use cannot be fixed and may frequently rely upon the free memory which is available on the physical server. When using a standalone web server, however, there's always a minimum amount of physical memory that shall be at your disposal at all times and will never be allocated to other customers even when it's not being used. That is valid with our virtual and dedicated hosting servers.
