When Datais Deleted From A Computer, Why Does It Follow A Law Of Conservation?

There is a proverb; "wasted not, wanted not." It says that one should not waste anything if he/she does not want to feel like needy for the rest of life. There are many things that we use in our daily life and that we discard off because we think that they are useless. But each and every thing has its own importance and nothing is useless.  

Computer is the most useful and eye catching invention of the present age. We use to work with it for many hours a day. It is a part and parcel of our daily work. Whenever we delete something, it goes to Recycle Bin first, then we decide either we need to clean Recycle Bin or not. That is what we called conservation. All those things which were left unsaved are not available for the present generation. So the computer is following the principle of conservation. So, nothing could be wasted at all. Computer has a number of pivotal documents which have their value over there in one way or the other. So, tis' better to follow the principle of conversation then to discard things by and by. Save things the way they matter.
