Answer:
Jen's laptop and her daughter's phone, because they are both connected to the router and turned on.
Step-by-step explanation:
A network comprises of two or more interconnected devices such as computers, routers, switches, smartphones, tablets, etc. These interconnected devices avail users the ability to communicate and share documents with one another over the network.
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.
