Processor interaction with memory and hard disk

The main difference between random access memory and magnetic media memory is that random access memory is volatile and soft
The data on the disk or on the hard drive remains, unless you intentionally delete or write the overlay. In addition, there is a significant difference only in
Understanding how microprocessors work can be understood: when a microprocessor outputs an address signal, it is usually addressed to a random
Memory, not magnetic media.
Removing data from disk to memory for microprocessor access requires additional steps, requiring a microprocessor to perform a small range of
To access the disk drive and enable the disk drive to transfer data to memory.
There is a metaphor for the difference between random access memory and magnetic Media memory: Random access memory is like a desktop
Something that can be used directly; Magnetic media memory is like a file cabinet, if you want to use something in a file cabinet, you need to
Stand up, go to the file cabinet, find the files you need, and bring them back to the desktop. If the desktop is too crowded, you need to
Something on the table was taken back to the file cabinet.
This metaphor is appropriate because the data on disk is actually stored in so-called "files". Store files,
Extracting files is an important part of the operating system's terms of reference.
