Final answer:
The 1000Base-T Ethernet standard specifies a maximum throughput of 1000 Mbps or 1 Gbps.
Step-by-step explanation:
The 1000Base-T Ethernet standard specifies a maximum throughput of 1000 Mbps (megabit), which is also equivalent to 1 Gbps (gigabit). This designation is part of the IEEE 802.3ab standard and is commonly used in wired local area networks (LANs). The '1000' in 1000Base-T indicates the maximum transmission speed of 1000 Mbps, 'Base' refers to baseband signaling, which means that the network has a single carrier frequency and uses the entire bandwidth for transmission, and 'T' stands for twisted pair cable, which is the type of cabling used with this standard.
