RAM, or Random Access Memory, is a sort of computer data storage, which allows the info to be read randomly without accessing the preceding bytes before that. This makes the RAM substantially faster than other sorts of storage devices like DVDs or HDDs where all the information needs to be read to be able to access particular information. In case you have a shared hosting account, the total amount of memory that your web apps can use cannot be fixed and may regularly depend on the free memory that's available on the physical machine. When using a standalone hosting server, however, there's always a minimum amount of physical memory that will be available at all times and shall not be assigned to other customers even if it is not used. That is valid with our virtual and dedicated servers.
