RAM, or Random Access Memory, is a type of computer data storage, which allows the data to be read randomly without accessing the preceding bytes before that. That makes the RAM considerably faster than other types of storage devices including DVDs or HDDs in which all the info needs to be read in order to access specific info. If you have a shared hosting account, the exact amount of memory that your web programs can use may not be fixed and may sometimes depend upon the free memory which is available on the physical server. When using a standalone hosting server, however, there's always a minimum amount of physical memory that will be for your use at all times and won't be allotted to other clients even if it is not in use. This is valid with our virtual and dedicated web servers.
