RAM, or Random Access Memory, is a kind of computer data storage, which allows the data to be read randomly without accessing the preceding bytes before that. This makes the RAM substantially faster than other sorts of storage devices including DVDs or HDDs in which all the information has to be read to be able to access certain information. When you have a shared hosting account, the amount of memory that your web apps can use may not be fixed and may commonly be determined by 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 will be available at all times and will not be assigned to other clients even when it is not used. That is valid with our virtual and dedicated servers.
