Main memory
Refers to physical memory that is internal to the computer.
The word main is used to distinguish it from external mass
storage devices such as disk drives. Another term for main
memory is RAM.

The computer can manipulate only data that is in main
memory. Therefore, every program you execute and every file
you access must be copied from a storage device into main
memory. The amount of main memory on a computer is crucial
because it determines how many programs can be executed at
one time and how much data can be readily available to a
program.

Because computers often have too little main memory to hold
all the data they need, computer engineers invented a
technique called swapping, in which portions of data are
copied into main memory as they are needed. Swapping occurs
when there is no room in memory for needed data. When one
portion of data is copied into memory, an equal-sized
portion is copied (swapped) out to make room.

Now, most PCs come with a minimum of 32 megabytes of main
memory. You can usually increase the amount of memory by
inserting extra memory in the form of chips.




Auxiliary memory

Data storing that computer doesn?t need immediately. The
most common auxiliary memory devices are tapes or disks. The
data can be loaded easily to the computer?s main memory when
needed.
