Understanding Network Topologies: The Sequential Chain

A network topology defines how devices (like computers, printers, etc.) are arranged and interconnected within a network. The question asks for the topology where devices are connected one after another in a sequential chain.

Analyzing the Options:

• Ring Topology: In a Ring topology, devices are connected in a circular path. Each device is connected to exactly two other devices, forming a ring. Data travels in one direction around the ring. This isn't a simple sequential chain connecting to a backbone.
• Tree Topology: This topology is a hybrid, combining characteristics of Bus and Star topologies. It features a central 'trunk' node, branching out to other nodes, creating a hierarchical structure. It doesn't fit the description of a single sequential chain for all devices.
• Star Topology: Here, all devices are connected to a central device, such as a hub or switch. All communication must pass through this central point. This is different from a sequential chain connection.
• Linear Bus Topology: This topology uses a single main cable (the bus or backbone) to which all devices are connected. Devices are attached along the length of the bus, effectively linking them in a sequence along this central cable. This perfectly matches the description of devices connecting 'one after the other in a sequential chain'.

Identifying the Correct Topology

Based on the definition, the Linear Bus Topology is the correct answer because it features a structure where devices are connected sequentially along a single backbone cable. Each device taps into this main cable, creating the described chain.
