Expect to come across this popular question in General interview questions.   This question is just to check the presence of mind and how you would explain some work to a newbie. You could answer the question by saying:  "Once the person woke up from the coma, I would ask him if he remembered anything from the last movie he watched where people used crystal balls with smoke in it to determine what was happening around them. I would tell him the internet is just like the crystal ball of the modern era. All you need to do is type or speak what you want you are looking for, and you will have the results in front of you. In addition to this, I will also tell him the advantages of the internet and how the world has evolved with its help of it."
