Explanation and Hint:
A device that forms the interface between users and the underlying communication network is known as an end device. End devices are either the source or destination of a message.
-
Which two methods are used to directly connect mobile devices such as tablets and smartphones to a data network? (Choose two.)
- wired Ethernet
- Bluetooth
- WiMax
- Wi-Fi
- cellular communications
Explanation and Hint:
Mobile devices connect wirelessly to data networks using either Wi-Fi or a telecommunication provider cellular network. Bluetooth is used to connect to peripherals or other local devices over very short distances. Ethernet is a wired network access technology and is not used by mobile devices. Mobile devices do not typically implement WiMAX technology.
-
What are two methods typically used on a mobile device to provide internet connectivity? (Choose two.)
- cellular
- GPS
- NFC
- Wi-Fi
- Bluetooth
Explanation and Hint:
Mobile devices commonly use Wi-Fi and cellular to connect to the internet. The cellular connection uses the cellular data network for a fee. The Wi-Fi connection uses an 802.11 wireless network in the area to connect to the internet.
-
In the context of mobile devices, what does the term tethering involve?
- connecting a mobile device to another mobile device or computer to share a network connection
- connecting a mobile device to a USB port on a computer in order to charge the mobile device
- connecting a mobile device to a hands-free headset
- connecting a mobile device to a 4G cellular network
Explanation and Hint:
Tethering allows a laptop or PC to use the Internet connection of a mobile device such as a cell phone, usually through a cellular data connection. This allows devices to connect to the Internet in locations where there is no Wi-Fi or cabled connection, but where there is still a cellular data connection.
-
