RAM, or Random Access Memory, is a type of computer data storage, which allows the information to be read randomly without accessing the preceding bytes before that. That makes the RAM a lot quicker than other kinds of storage devices including DVDs or HDDs in which all of the info ought to be read so as to access certain info. If you have a shared hosting account, the amount of memory which your web apps can use cannot be fixed and may regularly depend upon the free memory that is available on the physical server. With a standalone server, however, there's always a minimum amount of physical memory which will be for your use at all times and shall not be assigned to other customers even if it's not being used. That's valid with our virtual and dedicated web servers.
