Primary memory is faster to access because it is wired directly to the
processor. It is used by the system to perform operations while
programs are running. Examples are cache, RAM, and ROM.

Content in the primary memory lost once the computer system is turned off.

Secondary memory is usually somewhat slower and is used for permanent storage of
information. Examples are hard disks, floppy disks, DVDs, flash
memory, etc.

Content in the secondary memory remains intact even if the computer system is turned off.

Main memory is basically a physical memory which is internal to the computer. It is commonly known as RAM. The computer has to process all  the data that is in the main memory. Every file and program that is accessed or executed is stored or copied in the main memory.

On the other hand, a backing storage is a kind of computer storage device which has a larger capacity but whose access time is slower than that of the main memory. It is also known as bulk storage. This memory is external to the CPU. It is normally used to store data and programs that are not used currently. The examples include CD-ROM, floppy, magnetic tape or memory stick.

The invention of the computer has been one of the biggest events in recent history. The computer is a highly specialized machine, and the ability of man to create such a specialized machine speaks volumes about the evolution of the human mind. In fact, every new invention, each more complex than the other, is reaffirmation of the fact of evolution.

The computer has a very significant role in, besides other things, information technology. Developments in the field of information technology have largely been triggered by the availability of the computer. Information technology has itself been a landmark development. The Internet, for instance, has revolutionized to a large extent the way we live. Sending and receiving messages, conducting business transactions, and operating complex applications – all this is possible at the snap of a finger, literally, today. And all of this has as the base the computer; everything happens over the computer.

That is why the computer is considered very important from the information technology point of view.

Min memory is the communicate directly with the CPU. As secondary memory cannot.
As is Secondary memory is an old term methinks, referring to the storage medium. Hard drives, stuff like that.

Primary memory or main memory is where data is stored temporarily for quick access by the computer's processor. RAM and ROM are primary memory. The capacity of this memory is smaller.
Secondary storage are storage devices where data is stored permanently. It has larger storage capacity than primary memory. Examples of secondary storage are CD-ROM, floppy, magnetic tapes.

The primary memory of the main memory is of the computer. The processor can directly store and retrieves information from it. There are two types of primary memory RAM and ROM.

Secondary memory unlike primary memory is much slower but is far more cost effective and store the data permanently. Hard disk, floppy disk, CD/DVD Rom is the types of secondary memory.
