Final answer:
The IEEE standard for 1 Gbps Ethernet (1000BASE-T) is IEEE 802.3, which defines high-speed data transmission over a network.
Step-by-step explanation:
The IEEE standard associated with 1 Gbps Ethernet, also known as Gigabit Ethernet, is IEEE 802.3. This standard defines the protocols used for fast data transmission over a network. Specifically, 1000BASE-T is the IEEE standard that corresponds to Gigabit Ethernet over copper wiring. It enables data transfer at a rate of 1 gigabit per second (Gbps) and is widely used in networking equipment and interfaces for establishing high-speed network connections.
