RAM, or Random Access Memory, is a sort of computer data storage, which enables the information to be read randomly without accessing the preceding bytes before that. This makes the RAM a lot faster than other kinds of storage devices including DVDs or HDDs where all the data must be read in order to access certain info. If you have a shared hosting account, the total amount of memory which your web applications can use may not be fixed and may frequently depend on the free memory which is available on the physical hosting server. With a standalone server, however, there's always a minimum amount of physical memory that'll be readily available at all times and won't be allocated to other clients even when it isn't in use. That is valid with our virtual and dedicated servers.
