RAM, or Random Access Memory, is a type of computer data storage, that permits the information to be read randomly without accessing the preceding bytes before that. That makes the RAM considerably quicker than other sorts of storage devices like DVDs or HDDs where all of the data needs to be read so that you can access particular data. If you have a shared hosting account, the total amount of memory that your web apps can use can't be fixed and may sometimes rely upon the free memory which is available on the physical server. When using a standalone web server, however, there is always a minimum amount of physical memory that'll be for your use at all times and will not be allotted to other customers even if it is not used. That is valid with our virtual and dedicated hosting servers.
