RAM, or Random Access Memory, is a type of computer data storage, that enables the data to be read randomly without accessing the preceding bytes before that. This makes the RAM noticeably faster than other types of storage devices such as DVDs or HDDs where all of the data must be read so as to access particular info. In case you have a shared hosting account, the exact amount of memory your web programs can use may not be fixed and may sometimes depend on the free memory which is available on the physical hosting server. With a standalone web server, however, there's always a minimum amount of physical memory that'll be readily available at all times and will not be allotted to other customers even when it's not used. This is valid with our virtual and dedicated servers.
