Static Loading

Static loading is a software development concept where resources, such as code modules, libraries, or data, are loaded into memory at compile time or program startup, before execution begins. This contrasts with dynamic loading, where resources are fetched during runtime as needed. It is commonly used in compiled languages and for performance-critical applications to reduce latency and ensure availability.

Also known as: Static linking, Compile-time loading, Pre-loading, Early binding, Static binding

Why learn Static Loading?

Developers should use static loading when building applications that require predictable performance, such as embedded systems, real-time processing, or high-frequency trading, as it eliminates runtime overhead from loading operations. It is also beneficial for security-sensitive applications, as it prevents unauthorized code injection at runtime, and for optimizing startup times in desktop or server software where all dependencies are known in advance.
