RAM, or Random Access Memory, is a sort of computer data storage, that enables the information to be read randomly without accessing the preceding bytes before that. This makes the RAM considerably faster than other types of storage devices like DVDs or HDDs where all the information must be read to be able to access certain information. If you have a shared hosting account, the exact amount of memory which your web applications can use can't be fixed and may sometimes depend on the free memory that's available on the physical server. Using a standalone web server, however, there is always a minimum amount of physical memory that'll be available at all times and will not be allotted to other clients even when it is not being used. That's valid with our virtual and dedicated hosting servers.
