These standards define the physical and data-link layer specifications for Ethernet. The most important 802.3 standards are:
Notice how the first number in the name of the standard represents the speed of the network in megabits per second. The word base refers to baseband, meaning that the signals are transmitted without modulation. The last part of the standard name refers to the cabling used to
carry signals. For example, 1000Base-T means that the speed of the network is up to 1000 Mbps, baseband signaling is used, and the twisted-pair cabling will be used (T stands for twisted-pair).

It’s the highest rated Cisco course online with an average rating of 4.8 from over 30,000 public reviews and is the gold standard in CCNA training: It is supported by almost all modern equipment, offering good enough performance for most common applications. 1000BASE-T is used for general server interconnects and for endpoint client connections. Almost all networking equipment supports it on the access layer, although some backbone applications will require a faster standard. Most home equipment produced in the last decade will have Gigabit Ethernet. Institute of Electrical and Electronics Engineers (IEEE) standard 802.3ab defines 1000BASE-T, establishing it in 1999:
What are the 1000BASE-T specifications?1000BASE-T uses cheap and readily available cables that preexisted for many applications. It uses four twisted pairs for full-duplex communication -- simultaneous transmit and receive. The minimum standard is Cat5 cable, but it is readily compatible with all newer standards, such as Cat5e, Cat6, Cat6e and Cat8. 1000BASE-T maximum cable length is 100 meters (m), or about 330 feet. It uses the RJ45 connector and jack. 1000BASE-T operates at 1,000 Mbps, or 1 gigabit per second (Gbps). Automatic medium-dependent interface crossover is a standard feature for Gigabit Ethernet. This means that Gigabit ports can auto negotiate the transmit and receive twisted pairs in the cable. It, therefore, does not need crossover cables, and dedicated upload ports on switches are largely redundant. The physical medium attachment sublayer can potentially correct for nonstandard or reversed cabling. 1000BASE-T cabling is also compatible with some faster standards. 2.5GBASE-T (2.5 Gbps) and 5GBASE-T (5 Gbps) Ethernet can use the same Cat5e and Cat6 cables as Gigabit Ethernet. Extremely fast 10GBASE-T (10 Gbps) is capable over Cat6e cables. These standards are interoperable and auto-negotiated, enabling simple upgrade paths. This enables business and users to continue to use their existing wiring and increase available bandwidth with only relatively minor upgrades. What are other Gigabit Ethernet standards?There are other standards for Gigabit Ethernet. These use different types of cables than 1000BASE-T. They can be broadly divided into ones using copper cable and ones using fiber optics. Copper wire Gigabit Ethernet

Which type of Ethernet standard defines copper UTP cabling at 1 gigabit speeds?1000BASE-T is Gigabit Ethernet -- 1 gigabit is 1,000 megabits per second (Mbps) on copper cables, using four pairs of Category 5 (Cat5) unshielded twisted pair (UTP) to achieve the gigabit data rate.
What is the IEEE standard associated with Gigabit Ethernet?Gigabit Ethernet is defined in the Institute of Electrical and Electronics Engineers (IEEE) 802.3 standard and is currently being used as the backbone in many enterprise networks. Gigabit Ethernet connects computers and servers in local networks.
Which of the following are Ethernet standards?Fast Ethernet standards are specified in the IEEE 802.3u standard. Three standards are defined by 802.3u: 100BaseTX, 100BaseT4, and 100BaseFX. Of the three, the FX standard uses fiber-optic cable.
Which of the following Ethernet standards is also known as Fast Ethernet?The IEEE 802.3u is known as the Fast Ethernet standard. This is the standard that governs Ethernet cabled networks. It was established to accommodate high transmission speeds in cables.
