RAM, or Random Access Memory, is a form of computer data storage, which allows the info to be read randomly without accessing the preceding bytes before that. This makes the RAM noticeably quicker than other types of storage devices such as DVDs or HDDs in which all the information has to be read so that you can access certain data. In case you have a shared hosting account, the exact amount of memory that your web programs can use may not be fixed and may often be determined by the free memory that's available on the physical server. When using a standalone hosting server, however, there's always a minimum amount of physical memory which will be available at all times and shall not be allocated to other clients even if it is not used. That's valid with our virtual and dedicated web servers.
