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