When it comes to securing our data we often think that our data is safe when we store our data in these electronic/magnetic storage medias. But we often forget that even the hard copies of data can’t exist for a lifetime. Even when we write something on a piece of paper even we cannot claim to be forever there maybe the paper gets rot or the ink fades away. So how can we be so assured in case of these electronic devices. They also do have a life span. This deterioration in the quality and performance of data is known as data rot.
