An error is a runtime condition that cannot be handled by a program's normal flow of execution and is distinct from a bug, since it typically originates from conditions outside the program's control. Exception handling is the standard mechanism, dating to 1960s Lisp, for signaling and handling such conditions: exceptions form a class hierarchy rooted at a base exception type, are raised at the point of failure, and are caught and handled at an appropriate layer of abstraction, with resource cleanup guaranteed via constructs such as a "finally" clause or context managers that pair resource acquisition with guaranteed release. This belongs to the domain of programming language theory and software design, specifically control-flow and error-handling semantics.
