RAM, or Random Access Memory, is a form of computer data storage, that allows the information to be read randomly without accessing the preceding bytes before that. This makes the RAM considerably quicker than other kinds of storage devices like DVDs or HDDs where all of the information must be read so as to access certain information. When you have a shared hosting account, the total amount of memory which your web apps can use may not be fixed and may commonly depend upon the free memory that's available on the physical machine. Using a standalone server, however, there's always a minimum amount of physical memory which will be at your disposal at all times and will not be allotted to other clients even if it is not being used. This is valid with our virtual and dedicated hosting servers.
