CompTIA IT Fundamentals (FC0-U51) — Question 22

Which of the following technologies allows people to communicate all over the world inexpensively?

Answer options

• A. Virtualization
• B. SSID
• C. Kinetics
• D. VoIP

Correct answer: D

Explanation

VoIP (Voice over Internet Protocol) is the only option that specifically facilitates voice communication over the internet at a low cost. Virtualization, SSID, and Kinetics do not relate to global communication in the same way; virtualization pertains to creating virtual instances, SSID is related to wireless network naming, and Kinetics is not relevant to communication technologies.
