What type of network is characterized by computers linked in a circular layout where information is sequentially passed?

The network characterized by computers linked in a circular layout, where information is sequentially passed, is known as a token ring. In a token ring network, each device is connected in a ring configuration. This means that data travels in one direction around the ring until it reaches its destination.

The unique aspect of a token ring network is the use of a token – a small data packet – that circulates around the network. A device must possess the token in order to send data, which helps to prevent collisions and ensures orderly communication among the devices. This method of managing access to the network enhances efficiency and reliability, making it distinct from other network types.

In contrast, a star network features a central hub or switch that connects all devices independently, and communication occurs through this central point. A mesh network involves multiple interconnected devices, allowing for multiple pathways for data, increasing redundancy. A bus network has all devices connected along a single cable, and data is broadcast to all devices on that cable.

Therefore, the defining feature of a token ring network – its circular connection and the use of a token to manage communication, makes it the correct answer.
