Which architecture did FDDI and Token Ring networks use?

FDDI (Fiber Distributed Data Interface) and Token Ring networks utilize a ring architecture, which is essential for their functioning. In a ring network, devices are connected in a circular configuration, allowing data to travel in one direction from one device to the next in a continuous loop.

This topology is significant for both FDDI and Token Ring because it uses token-passing mechanisms to control access to the network. In this setup, a special data packet called a token is passed around the network. A device must possess the token to send data, which helps to prevent collisions and optimize network performance. The ring architecture is thus crucial for maintaining orderly communication and ensuring efficient data transmission.

In contrast, other architectures like bus, star, and mesh possess different methods of data transmission and network management, which do not inherently support the token mechanisms needed for these particular networking protocols. Therefore, understanding the ring architecture is central to comprehending how FDDI and Token Ring networks operate effectively.
