Which of the following describes cellular mobile network generations?

• A. Wired LAN
• B. VLANs
• C. Cellular (3G, 4G, 5G)
• D. Perimeter network

Answer: (C)

Cellular mobile network generations refer specifically to the advancements in mobile communication technologies, characterized by different standards and capabilities. The progression from 3G to 4G to 5G represents significant improvements in data speed, network capacity, latency, and overall service quality. Each generation introduces new technologies, protocols, and infrastructure improvements that collectively enhance mobile communication.

For example, 3G introduced mobile broadband internet services, allowing users to access the web and data applications on their devices, while 4G brought faster data speeds and the ability to stream high-definition video. 5G is the latest generation, designed to provide even greater speeds, lower latency, and the capacity to connect many more devices simultaneously, which supports the burgeoning Internet of Things (IoT) ecosystem.

In contrast, the other choices relate to entirely different networking concepts. Wired LAN refers to Local Area Networks using wired connections, while VLANs are Virtual Local Area Networks that separate networks without physical separation. A perimeter network, also known as a DMZ (Demilitarized Zone), is a network segment that adds an additional layer of security between an internal network and untrusted external networks like the internet. These do not describe the cellular mobile network generations, which specifically focus on mobile telecommunications
