How to explain difference between v&v give the example

Have you ever prepared an "Egg Omelette"! I am assuming that you have prepared. So how will you prepare an "Egg Omelette"? You will try to get all the ingredients required for making an "Egg Omelette" like - eggs, oil, salt, onion, and the other ingredients if any! Then what will you do? You will "verify" the ingredients and see if they are of good enough "quality" and in proper "quantity". Won't you? Here you are doing Verification.

Now let me assume that you have prepared "Egg Omelette". Now will you directly serve it to your guests? Or you would like to "taste" it to see if it has been prepared well? A good cook will choose to taste the dish before serving it to guests. This is comparable to Validation.
