Token Ringis a legacy networking technology defined by IEEE 802.5 and operates primarily at thePhysical Layer (Layer 1)of the OSI model, with some functions extending into the Data Link Layer.

The Physical Layer is responsible for transmitting raw bits over a physical medium, defining signaling, cabling, and transmission characteristics. Token Ring used a token-passing mechanism to control access to the physical medium, ensuring only one device transmitted at a time.

While modern Ethernet has replaced Token Ring, understanding its OSI placement remains important for foundational networking knowledge and certification exams.

Software-Defined Networking (SDN) separates the control plane from the data plane, enabling centralized and programmable network management.

Distributed Denial-of-Service (DDoS) attacks overwhelm targets with traffic from multiple sources, disrupting availability.

Availabilityensures that authorized users can access information and systems when needed, a core element of the CIA triad.
