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 quicker than other sorts of storage devices such as DVDs or HDDs in which all the data must be read so as to access particular data. In case you have a shared hosting account, the exact amount of memory which your web apps can use may not be fixed and may commonly be determined by the free memory that's available on the physical hosting server. Using a standalone hosting server, however, there's always a minimum amount of physical memory that will be readily available at all times and shall not be allocated to other clients even if it isn't being used. This is valid with our virtual and dedicated hosting servers.
