RAM, or Random Access Memory, is a kind of computer data storage, that enables the data to be read randomly without accessing the preceding bytes before that. This makes the RAM substantially faster than other types of storage devices like DVDs or HDDs in which all the information ought to be read so as to access particular data. If you have a shared hosting account, the total amount of memory that your web apps can use may not be fixed and may often depend on the free memory which is available on the physical web server. With a standalone web server, however, there is always a minimum amount of physical memory that will be at your disposal at all times and will never be allocated to other clients even if it's not being used. That is valid with our virtual and dedicated hosting servers.
