## about this topic

All software runs on top of hardware and an operating system — and understanding that layer is what separates someone who uses a machine from someone who commands it. This hub holds the CodeCrush articles on hardware and systems: how GPUs made the AI era possible, processor architectures, comparisons between Windows, Linux and macOS, quantum computing and the components that decide real-world performance. The guides translate technical specifications into practical decisions: which system to use for development, what actually makes a difference in a working setup, and where hardware evolution is taking computing over the next few years.
