Which of the following Ethernet standards supports the highest speed?

The standard that supports the highest speed is 10GBASE-T, which provides a maximum data rate of 10 Gbps. This standard operates over twisted pair cabling and is designed for high-performance networking environments, typically used in data centers and enterprise networks where high bandwidth is essential for applications such as virtualization and large data transfers.

In comparison, the other standards mentioned operate at significantly lower speeds. 10BASE-T runs at 10 Mbps, suitable for basic networking needs, while 100BASE-T supports up to 100 Mbps, which was common for early Ethernet networks. 1000BASE-T, or Gigabit Ethernet, operates at 1 Gbps, making it faster than its predecessors but still much slower than 10GBASE-T. This hierarchy of speeds is crucial for understanding network capabilities and designing networks that meet performance demands.
