What is the least intelligent network device?

When it comes to the realm of network devices, the question of what constitutes the "least intelligent" one can evoke various perspectives. Is it a device that lacks the ability to perform complex tasks or make decisions? Or perhaps, it's one that operates solely on basic instructions with little to no autonomy? One might argue that the simplest, most rudimentary devices like network switches or hubs, which primarily function as passive connectors, fall into this category. They lack the processing power and intelligence to perform advanced operations like routing decisions or filtering packets. Instead, they simply forward data packets based on pre-set rules or configurations. However, even these devices have some level of intelligence built into them, such as the ability to learn and remember MAC addresses for more efficient data forwarding. So, is there truly a "least intelligent" network device, or is it a matter of relative intelligence depending on the context and use case? In essence, the answer to this question may vary depending on one's definition of intelligence and the specific requirements of a given network environment. Nevertheless, it's an intriguing question that prompts us to think critically about the capabilities and limitations of the various devices that make up our interconnected digital world.
