The term memory refers to the amount of RAM installed in the computer and the storage refers to the capacity of the computer's hard disk. Memory storage devices have been drastically evolved in terms of size and capacity. The large trunks with the capacity to hold a few kilobytes of data, to microchips which are able to hold a few gigabytes of data. It is a component within your computer that allows for the short term access whereas storage is a component that allows you to store and access data on a long term basis.
Memory conversion is the conversion of data from one format to another. In the whole computer environment, the data is encoded in a variety of ways. Each computer handles data in different ways. When any of these variables is changed, the data must be converted in some way before it can be used by a different computer, operating system or the program. The changing of bits from one format to another, usually for the purpose of application interoperability or of capability of using new features is possible through the Memory Conversion (Data conversion).
