RAM, or Random Access Memory, is a sort of computer data storage, which enables the info to be read randomly without accessing the preceding bytes before that. That makes the RAM substantially quicker than other sorts of storage devices including DVDs or HDDs where all the info ought to be read to be able to access specific information. If you have a shared hosting account, the exact amount of memory which your web programs can use can't be fixed and may often rely upon the free memory that is available on the physical web server. When using a standalone hosting server, however, there is always a minimum amount of physical memory that'll be available at all times and shall not be assigned to other customers even when it isn't in use. That's valid with our virtual and dedicated web servers.
