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 substantially quicker than other types of storage devices such as DVDs or HDDs where all of the data ought to be read in order to access certain data. In case you have a shared hosting account, the total amount of memory your web applications can use cannot be fixed and may regularly depend upon the free memory that is available on the physical hosting server. When using a standalone web server, however, there is always a minimum amount of physical memory which shall be available at all times and shall not be assigned to other clients even when it is not used. That is valid with our virtual and dedicated servers.
