Private Versus Public WiFi – The Latter is Out of Your Hands
One of the first concepts to understand about WiFi is the private versus public connection. Public WiFi is the type you get in parks, cafes and libraries, universities, places which are (almost) open to everyone.

Private connections such as those at work or home can be made more secure with the next steps.
