What Ethernet standard operates at 10 Mbps?

The Ethernet standard that operates at 10 Mbps is 10Base-T. This standard is part of the IEEE 802.3 specification and was one of the early Ethernet standards that enabled networking over twisted pair cabling. The "10" in 10Base-T indicates the speed of 10 megabits per second, while "Base" denotes baseband signaling and "T" signifies twisted pair cabling.

This technology primarily uses unshielded twisted pair (UTP) cabling, which helps in reducing electromagnetic interference and allows for effective communication over relatively short distances, typically up to 100 meters. Understanding this foundational standard is important as it laid the groundwork for subsequent developments in Ethernet technology.

In contrast, the other options refer to faster Ethernet standards. For instance, 100Base-T operates at 100 Mbps (Fast Ethernet), while Gigabit Ethernet achieves speeds of 1 Gbps (1000 Mbps). Thus, it is essential to recognize the capabilities and specifications of each standard to properly identify their respective operational bandwidths. In this case, 10Base-T is clearly defined by its 10 Mbps performance.
