Fiber Distributed Data Interface (FDDI): This technology uses a dual-ring topology, primarily over fiber optic cabling, to achieve data rates up to 100 Mbps. FDDI's dual-ring structure provides redundancy, allowing the network to operate even if one ring fails. It was suitable for high-speed backbone applications before Gigabit Ethernet became widespread.
Attached Resource Computer NETwork (ARCNET): ARCNET is an older LAN technology that often used a bus or star topology, typically with coaxial cable. It employs a token-passing access method, where a token circulates among connected devices, granting permission to transmit data. Its data rate was limited to 2.5 Mbps. ARCNET was known for its simplicity and robustness, finding use in industrial and embedded systems.
