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. That makes the RAM significantly faster than other types of storage devices like DVDs or HDDs in which all of the information needs to be read in order to access particular information. When you have a shared hosting account, the amount of memory that your web apps can use cannot be fixed and may regularly depend upon the free memory that is available on the physical hosting server. Using a standalone hosting server, however, there is always a minimum amount of physical memory that shall be for your use at all times and shall not be assigned to other customers even if it isn't used. That's valid with our virtual and dedicated servers.
