Jen’s house contains the following devices: Jen’s laptop, which is turned on and wirelessly connected to the home network router Her husband’s PC, which connects to the router by a cable but is turned off Her mother’s virus-infected computer, which has been unplugged from the router Her daughter’s smart phone, which is wirelessly connected to the router If Jen’s daughter is talking on her phone, and Jen’s husband’s computer is off, which computers are currently networked?
Answer
A
Just Jen’s laptop, because her mom’s computer is not connected to the router, her husband’s computer is off, and her daughter’s phone is not currently acting as a computer.
B
None of them, because a network must have at least two devices wired by cable before it can be called a network.
C
Jen’s laptop and her daughter’s phone, because they are both connected to the router and turned on.
D
All four, because they are all computers in the house, regardless of their present usage.
