SOFTWARE LIBRARIES Meaning and
Definition
-
Software libraries are collections of pre-written code modules, procedures, or functions that serve as building blocks for applications and enable developers to add specific functionality to their programs without having to write the code from scratch. These libraries contain reusable code components that can be readily integrated into various software projects. They are typically designed by software experts to provide common or complex functionalities that are frequently required in many applications.
Software libraries offer a range of advantages to developers. Firstly, they save time and effort by eliminating the need to reinvent the wheel every time a particular functionality is required. Developers can simply utilize the pre-existing code, reducing development cycles and speeding up time-to-market. Moreover, software libraries enhance code reuse and modularity, leading to more efficient and maintainable software systems. They promote consistency by providing standardized functions that adhere to specific programming paradigms or conventions, ensuring uniformity across different applications.
There are various types of software libraries available, catering to different programming languages, platforms, and domains. General-purpose libraries encompass a wide array of functionalities and can be used in various applications. Domain-specific libraries, on the other hand, are tailored to particular domains or industries and provide specialized functionalities. Popular examples of software libraries include Java Platform, Standard Edition (Java SE) class libraries, .NET Framework Class Library, and Boost C++ Libraries.
In conclusion, software libraries serve as repositories of pre-written code that offer convenience, speed, and efficiency in the development process. They empower developers by providing well-tested and reusable components that enable the creation of robust and feature-rich software applications.
Etymology of SOFTWARE LIBRARIES
The word "software libraries" is composed of two parts: "software" and "libraries".
1. "Software" refers to a collection of computer programs, data, or instructions that tell a computer how to perform specific tasks or functions. It comes from the combination of "soft" and "ware".
- "Soft" contrasts with "hard" and refers to anything that is not a physical object, such as data or instructions. Originally, "soft" described "soft logic", which refers to electronic circuitry using electronic transistors. Later, it evolved to encompass software.
- "Ware" is derived from the Old English word "waru", which means "article" or "commodity". It is often used as a suffix to indicate a product.
2. "Libraries" are collections of precompiled code modules or functions that developers can use to simplify the creation of software.
