RAM, or Random Access Memory, is a kind of computer data storage, which enables the information to be read randomly without accessing the preceding bytes before that. That makes the RAM significantly quicker than other types of storage devices such as DVDs or HDDs where all the info ought to be read so as to access certain data. In case you have a shared hosting account, the amount of memory which your web apps can use cannot be fixed and may commonly be determined by the free memory that is available on the physical server. When using a standalone server, however, there is always a minimum amount of physical memory that shall be for your use at all times and will never be allocated to other customers even if it isn't used. That's valid with our virtual and dedicated web servers.
