Which network topology connects devices to a shared straight-line cable?

The correct answer is the bus topology, which connects all devices to a single, shared communication line or cable. This configuration allows data to travel along the cable in either direction and each device listens for messages intended for it. When a device sends data, it is broadcasted across the entire cable, and the intended recipient recognizes its own data from the incoming traffic.

Bus topology is straightforward and cost-effective for small networks due to its simplicity in design and minimal cabling requirements compared to other topologies. However, it can become less efficient as more devices are connected, and a failure in the main cable can disrupt the entire network.

Other network topologies are structured differently. For instance, in star topology, each device is connected to a central hub or switch, which facilitates communication. Hybrid topology combines two or more different topologies, adapting to various needs. In contrast, ring topology connects each device in a circular fashion, where data travels in one direction, passing through each device until it reaches its destination. Understanding these distinctions helps in selecting the appropriate topology based on specific network requirements.
