RAM, or Random Access Memory, is a sort of computer data storage, that permits the info to be read randomly without accessing the preceding bytes before that. This makes the RAM noticeably faster than other sorts of storage devices including DVDs or HDDs where all of the info ought to be read so that you can access specific data. If you have a shared hosting account, the exact amount of memory that your web apps can use can't be fixed and may commonly be determined by the free memory that is available on the physical hosting server. When using a standalone hosting server, however, there's always a minimum amount of physical memory that will be available at all times and will not be allocated to other customers even when it's not used. This is valid with our virtual and dedicated web servers.
