2.7 Hands-On with WANs Flashcards
What are the most common WAN technologies?
Cable modems, fiber optic modems, satellite modems, and cellular connections.
What type of connection do cable modems use?
Coaxial cables.
What is the role of a media converter in a fiber optic network?
It transitions from fiber to coaxial or copper (Cat6) connections.
Why are satellite modems used?
They provide internet access in remote areas where cable or fiber is unavailable.
How do satellite modems connect to the ISP?
A coaxial cable runs from the satellite dish to the modem, which then converts the signal to an RJ45 Ethernet connection.
What is a mobile hotspot?
A device that connects to a cellular network and shares the internet via Wi-Fi.
What type of connection do fiber modems use?
Fiber optic cables, often requiring media converters for Ethernet.
What type of connection do satellite modems use?
Coaxial cables from a satellite dish.
What are the most frequently encountered WAN technologies?
Cable, fiber, and cellular.
Where are satellite modems commonly used?
In remote areas with no access to cable or fiber.
How do cellular networks provide WAN access?
Through mobile hotspots or tethered devices that connect to a cellular data network.
Why is understanding media converters important for technicians?
They are required to connect fiber networks to copper-based devices like Ethernet routers.
What device converts a satellite signal into a usable internet connection?
A satellite modem.
What are some key differences between cable and fiber modems?
Cable modems use coaxial cables, while fiber modems require media converters to transition fiber signals to Ethernet.
What kind of Ethernet connection do most WAN modems output?
RJ45 (Cat6) Ethernet.
