Global

In computer science, „Global“ refers to a scope or context that is accessible from anywhere within the program or system. This term is often used in relation to variables, functions, or data structures that are declared in a global scope, meaning they can be accessed and modified by any part of the code, regardless of where they are called from.

Global variables, for example, are defined outside of any function or class, making them available throughout the entire program. While global variables can be useful for sharing data and state across different parts of an application, they can also introduce challenges related to namespace collisions and unintended side effects, making code harder to maintain and debug.

In the context of programming languages, the concept of „global“ can vary in implementation. Some languages adopt a global namespace for certain elements, while others allow for more controlled access through encapsulation and modularity. Regardless, the core idea revolves around the unrestricted accessibility of resources defined in the global context.
