Instructions Competition Mode: For each correct answer, you get points based on how many other players get the question wrong. Your score is the sum of all correct answers.

Example: If you get a question correct that only 10% of all players get correct, you get 90 points for that question.

You can choose 5 questions to "Double". If you get it correct, your score is doubled for that question.

TIP: Easy questions aren't usually worth doubling since you are likely doubling a small number of points. You're better off doubling the hardest questions that you think you have correct (80 points possibly doubled is a lot better than 10 points definitely doubled).

You will not lose points for incorrect answers, so feel free to guess.

You can enter up to three group names, separated by commas, in the "Private Group" input. After you submit, when you view your results you can see the leaderboards for just your group(s). You will also get links you can share with others so they can play in those groups.
Feel free to create your own group name, such as your company or town, and pass the links along to friends, family, and coworkers.

Good luck!
    
 
Question #17: Technology: The term LAN applies to networks that connect computers within a limited area, and WAN is used for networks over wider areas. What similar three-letter acronym, a specific type of WAN, is used for mobile telecom systems, of which GSM, LTE, and 5G NR are examples?

Answer: RAN
Mobile systems implement radio access technology to connect user equipment (UE), often a phone, to a core network (CN). It is possible for a UE to be simultaneously connected to multiple RANs, such as those that use 5G for data transmission and LTE for control; these UEs are sometimes called dual-mode handsets.
