Additionally, in order for a network to exist or be established, the devices must be turned (powered) on and interconnected either wirelessly or through a cable (wired) connection.
Hence, the computers which are currently networked are Jen's laptop and her daughter's phone, because they are both connected to the router and turned on. A smartphone is considered to be a computer because it receives data as an input and processes the input data into an output (information) that is useful to the end user.
