The Internet for most of us now is never farther than a click away. Whether this “click” was performed by a mouse button, when using your laptop or desktop PC, or by a touch to the screen of your smart phone, or tablet. You almost never wonder how it happens that when you launch your favorite messaging application, the first thing in the morning, it retrieves all those messages that your family members, friends, colleagues, clients, etc. have sent over the night, while you were asleep. This is just normal.
