No, modern LANs use a star topology
Bus topology LANs are very rare these days. It would be easier to use a star topology than a bus topology for a few devices.
Bus topology is extended via the use of repeaters.

Most LANs use UTP cable, category 5 or better.
Sure, the machines have to be connected somehow. A star topology is quite common.
The most common topology in use today is the star topology, primarily due to its scalability and ease of management. This topology often utilizes Ethernet technology, particularly with twisted-pair cabling, which is prevalent in local area networks (LANs). The star topology allows for easy addition and removal of devices without disrupting the network, making it ideal for modern networking needs. Additionally, advancements in wireless technology have also popularized star topology in Wi-Fi networks.
Star topology is very common; chances are any company you can think of (big or small) is using a star in their LANs somewhere within the company.
Local area networks (LANs) commonly use several topologies, with the most prevalent being star, bus, and ring topologies. The star topology connects all devices to a central hub or switch, facilitating easier management and fault isolation. The bus topology involves a single central cable to which all network devices are connected, while the ring topology connects devices in a circular format, where data travels in one direction. Each topology has its advantages and disadvantages, influencing its selection based on network size and requirements.
A bus topology for a LAN will typically use coaxial cable, either 10Base5 (thicknet) or 10base2 (thin-net) copper wiring.
Bus Network Topology.
SONET use RING physical topology and TOKEN logical topology. As simple as that. Logical topology deals with the data transmission. Physical topology deals with how the network is connected physically , BUS, RING, STAR and the like.
