Today most of the systems come with 1 GB or 2 GB RAM for optimal performance when using graphical and multimedia programs. People in computer industry commonly use the term memory to refer to RAM. A RAM is used to store temporary instructions and data needed to complete needed tasks. This enables the CPU to access instructions and data stored in memory very quickly. For example many application programs such as word processing or page layout are using this procedure. The term memory refers to amount of RAM installed in the computer, but the term storage refers to the capacity of the computer’s hard disk. Another important difference between memory and storage is that whatever data is stored in memory is lost when computer is turned off but whatever remains in the hard disk remains intact. Thus we see that the hard disk is non volatile whereas the RAM is a volatile form of memory. RAM as we have seen is only for instant access of data.
