RAM, or Random Access Memory, is a sort of computer data storage, that permits the data to be read randomly without accessing the preceding bytes before that. That makes the RAM substantially quicker than other sorts of storage devices including DVDs or HDDs in which all the info ought to be read so that you can access certain data. When you have a shared hosting account, the total amount of memory that your web programs can use can't be fixed and may sometimes be determined by the free memory that is available on the physical server. When using a standalone web server, however, there is always a minimum amount of physical memory that shall be available at all times and will never be assigned to other clients even when it's not in use. That is valid with our virtual and dedicated hosting servers.
