Which benefit does open system architecture provide?

Open system architecture primarily facilitates interoperability between different systems. This design approach allows different hardware and software components from various vendors to communicate and work together seamlessly. By adhering to open standards and protocols, systems can exchange data efficiently and integrate with one another, regardless of the underlying technology or manufacturer.

In contrast, reducing system complexity may not be a direct benefit of open system architecture; while it can simplify integration, it does not inherently simplify the overall system structure. Ensuring data encryption is more related to security measures that can be implemented within any kind of architecture, but it is not a specific benefit associated with open systems. Additionally, increasing vendor lock-in is generally contrary to the principles of open systems, which aim to diminish reliance on a single vendor by promoting choice and flexibility in component selection.
