RAM, or Random Access Memory, is a form of computer data storage, that enables the info to be read randomly without accessing the preceding bytes before that. That makes the RAM significantly faster than other kinds of storage devices such as DVDs or HDDs in which all of the info needs to be read so that you can access certain information. When you have a shared hosting account, the exact amount of memory that your web applications can use can't be fixed and may sometimes depend upon the free memory which is available on the physical machine. Using a standalone server, however, there's always a minimum amount of physical memory that shall be available at all times and won't be assigned to other customers even when it is not being used. This is valid with our virtual and dedicated hosting servers.
