A function is formally defined as a computational entity that accepts zero or more arguments as inputs and produces a single return value or performs a specific side effect without returning. The core mechanism involves invoking the function by referencing its name followed by parentheses containing the argument list, which triggers the execution of the defined logic. This concept belongs to the domain of computer science theory, specifically within the sub-field of programming language semantics and software architecture, serving as a fundamental abstraction for modularity, code reuse, and the separation of computation logic from data.
