Which type of Ethernet topology is characterized by devices connected in a single line?

Linear topology is characterized by devices being connected in a single line, with each device connected to the next one in sequence. This arrangement allows for a straightforward way of connecting multiple network devices, making it relatively simple to set up. In a linear topology, data packets travel along the single line from one device to another until they reach their destination.

This type of topology is efficient for small networks and can be easier to manage and troubleshoot since there is a clear path for data transmission. However, it can lead to limitations; for example, if there is a break in the line, it can disrupt communication across the entire topology.

In contrast, other types of topologies such as star or mesh involve more complex interconnections that do not follow a single-line structure. Star topology connects all devices to a central hub or switch, while mesh topology creates a network where devices are interconnected with multiple paths, enhancing redundancy and reliability. Meanwhile, hierarchical topology organizes devices in a tree structure, which can also involve multiple levels of connections, rather than a simple linear configuration.
