### In the lessons

In computing lessons, wifi is a wireless network that uses a router; pupils learn that data travels as radio signals. In online-safety lessons, children learn not to join unknown public wifi without an adult and to keep the wifi password private. In everyday life, «What's the wifi password?» is a common question. Phrases: «the wifi password», «free wifi», «connect to the wifi», «wifi signal».
