Internet of Things (IoT) Practice Exam

Which of the following statements about Wi-Fi technology is incorrect?

1. Wi-Fi enables local area networking using radio waves

2. Wi-Fi is equivalent to wired Ethernet networks

3. Wi-Fi can provide high-speed internet connections

4. Wi-Fi supports a variety of devices with different standards

The correct answer is: Wi-Fi is equivalent to wired Ethernet networks

The statement regarding Wi-Fi being equivalent to wired Ethernet networks is incorrect because while both technologies serve the purpose of providing network connectivity, they operate differently and have distinct characteristics. Wi-Fi utilizes radio waves to connect devices wirelessly, making it convenient for mobility and flexibility within a local area. In contrast, wired Ethernet relies on physical cables for connection, which generally leads to more stable and higher speeds with less interference. While Wi-Fi can indeed deliver high-speed Internet connections, support multiple devices, and enable local area networking, it does not match the efficiency and reliability often provided by wired Ethernet, especially in environments requiring high throughput or low latency. This essential distinction between wireless and wired technologies highlights why the assertion that they are equivalent is inaccurate.
