Ethernet, which is fast, simple, and ubiquitous, is a technology that has numerous practical applications. The hardware for Ethernet connections is widely available, and it is supported by many microcontrollers and SoCs. Additionally, Ethernet can be used for establishing high-bandwidth connections between various devices, such as Linux boards and powerful MCUs, as well as for creating networks between microcontrollers.

Furthermore, Ethernet is highly scalable, and the availability of cables, connectors, and ICs for Ethernet is abundant. Beyond the consumer-facing versions of Ethernet that are commonly known, there are also industrial and automotive Ethernet standards that offer unique functionalities.

Despite the widespread use of Ethernet, there are still misconceptions and misunderstandings about how it works. For instance, individuals may be unaware of the benefits of Ethernet or may not know how to interpret certain terms and specifications related to Ethernet interfaces on devices.

This lack of understanding can lead to confusion, such as not knowing what to do with the Ethernet pins on a single board computer or being unsure of the significance of additional chips required for Ethernet support in certain devices. Moreover, concepts like GMII (Gigabit Media Independent Interface) may be unfamiliar to individuals who are not well-versed in Ethernet technology.

To address these issues, a comprehensive understanding of the basics of Ethernet is crucial. By gaining knowledge about Ethernet, individuals can make informed decisions about utilizing this technology in various applications and scenarios.

In conclusion, Ethernet is a versatile and essential technology with a wide range of practical uses. By familiarizing themselves with the fundamentals of Ethernet, individuals can harness the full potential of this technology and effectively integrate it into their projects and devices.
