RAM, or Random Access Memory, is a kind of computer data storage, which allows the information to be read randomly without accessing the preceding bytes before that. This makes the RAM significantly faster than other types of storage devices including DVDs or HDDs in which all of the info needs to be read so as to access certain data. If you have a shared hosting account, the amount of memory your web programs can use can't be fixed and may often depend upon the free memory which is available on the physical hosting server. When using a standalone hosting server, however, there is always a minimum amount of physical memory that shall be at your disposal at all times and will not be allocated to other clients even when it's not used. This is valid with our virtual and dedicated web servers.
