An open system in computing is characterized as one that allows for interaction and integration with other systems. This means that it can communicate and share data with different types of hardware, software, and platforms, which is essential for fostering interoperability and collaboration. Open systems typically adhere to standard protocols and formats, making it easier for developers to build compatible applications and services.

This concept contrasts with systems that are closed or proprietary, which may have restricted access, limit modifications, or be designed to operate in isolation. For instance, proprietary systems often utilize unique interfaces or protocols that only work within that specific ecosystem, hindering integration with other technologies. A system with no user interface would not typically fall under the definition of an open system, as user interface aspects are separate from the system's capability to interact and integrate with other systems. Thus, the defining feature of an open system is its ability to engage with various external entities, enhancing flexibility and potential for growth.
