IOGs

IOGs is an acronym that can refer to multiple organizations or concepts, depending on the context. In blockchain and cryptocurrency, IO Global (IOG) refers to a technology company that develops and maintains the Cardano blockchain ecosystem. The entity originated as IOHK (Input Output Hong Kong) and was renamed Input Output Global in 2020. IOG engages in research, protocol development, and tooling for Cardano, including software libraries, node software, and academic collaborations. A related legal structure is the IOG Foundation, established to support Cardano ecosystem research, education, and community initiatives.

In computing, IOGs commonly stands for I/O groups, a concept used in high‑performance and enterprise systems to categorize input/output resources. An I/O group is a collection of devices, ports, and memory channels that share bandwidth or are allocated together for performance and resource management. Organizing devices into IOGs can simplify scheduling, isolation, and throughput optimization in multi‑socket servers, storage arrays, and HPC environments.

Other uses of the acronym exist in specialized domains, but they are far less common. As with many acronyms, the exact meaning of IOGs is highly dependent on the field and the surrounding terminology. When encountering the term, readers should rely on contextual clues, such as references to Cardano, IOHK, or I/O performance, to determine the intended meaning.
