RAM, or Random Access Memory, is a type of computer data storage, which enables the data to be read randomly without accessing the preceding bytes before that. That makes the RAM noticeably faster than other sorts of storage devices including DVDs or HDDs where all of the information ought to be read in order to access specific information. If you have a shared hosting account, the total amount of memory your web programs can use can't be fixed and may sometimes be determined by the free memory which is available on the physical machine. When using a standalone web server, however, there is always a minimum amount of physical memory which shall be readily available at all times and will not be assigned to other clients even when it isn't used. This is valid with our virtual and dedicated web servers.
