Non Volatile Memory Described

Many of us now a days becoming an Information Technology Geeks and we know about the using mechanism of our system basically.
But We forget to know interestingly about
HOW OUR SYSTEM WORKS?
So, let's get started

Our Computer System are divided into two parts
Known as HARDWARE & SOFTWARE SYSTEM. We known something about the hardware and the most famous one is our harddrive commonly known as HDD. So we will learn and get into the some deeper concepts of our Hard drive.
Non Volatile Memory

Non Volatile the word means the stability. Volatile means unstable or temporary.
Volatile memory mainly consists of RAM ( Random Access Memory) and Cache memory.
The data saved on the volatile memory is Temporarily saved and it is in the memory till the power supply is connected to the circuit.
Now we come to NON - VOLATILE MEMORY .
Non Volatile Memory used for storing the data and the data will not be lost even if the power supply gets disrupted. This is used for permanent data saving purpose only. Our Hard Drives are comes into the category of non volatile memory.
Non volatile memory are practically slower than the volatile memory and the research is being conducted for get rid of slower performance given by the non volatile memory.
Non volatile memory are the Read Only Memory i.e. they are being used to store the data and Volatile memory used to run the program or open the data.
They are two types of Non Volatile Memory are there:-
1-- Electrically Addressed Memory
2-- Mechanically Addressed Memory

Electrically Addressed Memory is expensive compare to Mechanically Addressed Memory.
Mechanically Addressed Memory is slower and the Electrically Addressed Memory is much faster in processing. The cost of Electrically Addressed Memory is decided by unit of bit. Per bit costs some amount of money.
You explained this in a way that is easy to understand. Nice work.
