RAM, or Random Access Memory, is a form of computer data storage, which allows the info to be read randomly without accessing the preceding bytes before that. That makes the RAM a lot faster than other kinds of storage devices such as DVDs or HDDs in which all of the information needs to be read so as to access specific info. When you have a shared hosting account, the amount of memory your web apps can use may not be fixed and may frequently depend on the free memory which is available on the physical web server. When using a standalone hosting server, however, there's always a minimum amount of physical memory that will be for your use at all times and will never be allocated to other customers even if it is not being used. That's valid with our virtual and dedicated hosting servers.
