Ethernet uses.
Ethernet uses Bus topology.
Ethernet is the most widely used network topology. You can choose between bus and star topologies, as well as coax, twisted-pair, or fibre optic cabling. And with the right connective equipment, multiple Ethernet-based LANs can be linked together.
The most common bus topology network is Ethernet. Coaxial cable has been its primary transmission media, although twisted-pair wire is now used in most new installations. Twisted-pair Ethernet (10Base-T) is a star-configured bus topology.
Because early bus topology networks used bulky coaxial cables, these factors were important advantages. Both 10BASE-5 (thick) and 10BASE-2 (thin) Ethernet networks are based on the bus topology. A 10BASE-2 network is an example of a linear bus topology, attaching all network devices to a common cable.Nov 1, 2011
