COM

Definitions

COM is Microsoft's Component Object Model for binary software components and interface-based interop. It is commonly used for desktop application extensibility and Windows automation, where teams need predictable behavior under real workloads rather than toy examples. Practitioners pay attention to registration issues, reference counting, and binary compatibility, because those factors usually determine whether the approach improves quality, latency, reliability, or operating cost in production.
In plain English: COM is a software engineering concept that helps developers structure code, run systems, or debug behavior more reliably in real projects.
Example: "We standardized on COM in this service because the old approach was fragile under load; the new implementation reduced operational surprises and made the codebase easier for the next engineer to reason about."
