A user is at a public library and wants to connect their laptop to the available Wi-Fi. Which of the following components is LEAST likely to be required to establish the connection?
A wireless network interface card (WNIC)
The network's Service Set Identifier (SSID)
A password for the network
An RJ-45 cable
To connect a device like a laptop to a Wi-Fi network, a wireless network interface card (WNIC) is necessary to send and receive the radio signals. The user also needs to know the network's name, the Service Set Identifier (SSID), to select the correct one from the list of available networks. If the network is secured, a password will be required to gain access. An RJ-45 cable, also known as an Ethernet cable, is used for wired network connections and is not needed to connect a client device to a wireless network.
