Question 25

Explanation

The correct answer: Shared communication medium: Baseband communication refers to a communication method in which data is sent over a single, dedicated line. This means that only one signal is transmitted at a time, with the entire bandwidth of the network cable being utilized. This differs from broadband communication, which allows multiple signals to be transmitted simultaneously by dividing the bandwidth into multiple channels. Hence, baseband networks are a shared communication medium, and this is one of their key features. The incorrect answers: High data rates: While baseband solutions can potentially offer high data rates, this is not their key distinguishing feature. Many other network solutions can also provide high data rates, including both broadband and fiber-optic solutions. Furthermore, because baseband solutions transmit one signal at a time, their data rates might not be as high as those of broadband solutions in certain circumstances. Limited distance between devices: The distance between devices in a baseband network isn't particularly limited or a key feature of such solutions. The actual distance that a baseband signal can cover is often determined by factors such as the quality of the transmission medium, the power of the signal, and the sensitivity of the receiving equipment. While it's true that signal degradation can occur over long distances, this is not exclusive to baseband solutions and is, therefore, not a defining characteristic. Strong security protocols: While security is certainly important in any network implementation, it's not a key feature unique to baseband solutions. Both baseband and broadband systems can be made secure through the use of various protocols and encryption methods. The level of security largely depends on the specific protocols used and the diligence of the network administrators, rather than being an inherent attribute of baseband systems.
