Lori wants to set up a SOHO network in her apartment. The apartment comes with a Gigabit Ethernet network already installed. Lor

Yanka [14]

Connection to the gigabit ethernet network must be done with Cat6 Cable. Using the wireless ethernet router as the network device and connecting the cable to the printer must be done with Cat5e Cable.

We can arrive at this answer because:

The Cat6 Cable will be responsible for establishing a bridge between the gigabyte Ethernet and the network device, allowing data delivery to be made between the two systems.

This connection must be made with a wireless device, to keep it more stabilized and it needs, mainly, for the notebook to receive the internet signal. This will be done using the wireless ethernet router.

The printer needs a softer, less rigid connection, so a Cat5e cable will be a convenient option.

In this case, we can see that using these devices will allow Lori to have a more stable and efficient connection to meet her needs.
