10 Gbps

The correct answer is: 1 Gbps

The 1000BaseT standard, which is part of the IEEE 802.3ab specification for Ethernet, defines a transmission speed of 1 Gbps (gigabit per second). This standard facilitates high-speed data transmission over twisted-pair cabling, specifically using Category 5 and higher cables. It operates over a distance of up to 100 meters, which allows for significant bandwidth suitable for modern networking needs. In the context of Ethernet standards, 1000BaseT is a notable advancement over earlier standards like Fast Ethernet (100BaseT), which supports 100 Mbps. The distinctions in speed reflect the technological advancements in networking that have allowed for faster and more efficient data communication, shifting towards higher demands for internet and network performance in contemporary environments.
