Binäärikirjastojen

Binäärikirjastot, also known as binary libraries or shared libraries, are collections of pre-compiled machine code that can be loaded and used by multiple programs simultaneously. These libraries contain functions and data that can be accessed by applications, reducing the need to duplicate code across different executables. This approach saves disk space and memory, as the library code is only loaded into memory once and shared among all programs that use it.

The use of binary libraries is a fundamental aspect of modern operating systems and software development. They allow for modularity, enabling developers to create and update components independently. When a program needs to perform a specific task, such as reading a file or displaying graphics, it calls a function from a relevant binary library. The operating system then locates and loads the necessary library into memory if it isn't already present.

Common examples of binary libraries include dynamic-link libraries (DLLs) on Windows and shared objects (.so files) on Linux and macOS. These libraries are typically linked at runtime, meaning the program doesn't contain the library's code directly but rather references to its functions. This dynamic linking provides flexibility, as libraries can be updated or replaced without recompiling the applications that use them, as long as the interface remains compatible. This mechanism is crucial for system updates and the maintenance of software ecosystems.
