RAM, or Random Access Memory, is a type of computer data storage, that permits the info 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 of the info has to be read so that you can access particular info. In case you have a shared hosting account, the exact amount of memory which your web applications can use can't be fixed and may commonly depend on the free memory which is available on the physical web server. Using a standalone web server, however, there's always a minimum amount of physical memory that shall be for your use at all times and shall not be allotted to other customers even if it's not in use. That's valid with our virtual and dedicated servers.
