In the context of technology and software development, a library refers to a collection of pre-written code or software components that can be reused in different programs. A library usually includes functions, classes, or other objects that have been designed to solve a specific problem or perform a specific task.
Libraries can be either proprietary or open-source, and they are widely used by developers to save time and effort in building new software applications. By using pre-built libraries, developers can avoid the need to write everything from scratch, and can focus on the unique aspects of their project.
Libraries can be stored in a variety of formats, such as dynamic link libraries (DLLs), static libraries, or shared object libraries, depending on the programming language and the operating system being used. They can be included in a project by linking or importing them into the code.
Overall, libraries are an essential tool for developers, enabling them to build better software in less time and with fewer errors.
