RAM, or Random Access Memory, is a form of computer data storage, that permits the data to be read randomly without accessing the preceding bytes before that. That makes the RAM a lot quicker than other types of storage devices such as DVDs or HDDs where all of the data must be read to be able to access specific information. When you have a shared hosting account, the amount of memory that your web apps can use may not be fixed and may often be determined by the free memory that's available on the physical hosting server. Using a standalone web server, however, there is always a minimum amount of physical memory that'll be readily available at all times and will not be allotted to other clients even if it's not used. That is valid with our virtual and dedicated hosting servers.
