RAM, or Random Access Memory, is a kind of computer data storage, that permits the data to be read randomly without accessing the preceding bytes before that. That makes the RAM a lot quicker than other types of storage devices like DVDs or HDDs in which all the data ought to be read to be able to access certain information. If you have a shared hosting account, the amount of memory that your web programs can use can't be fixed and may sometimes depend on the free memory that is available on the physical web server. When using a standalone server, however, there's always a minimum amount of physical memory which will be readily available at all times and won't be assigned to other customers even when it's not being used. That's valid with our virtual and dedicated servers.
