Context-free grammar. Simplified excerpt of the formal grammar [1] for the C programming language (left), and a derivation of a piece of C code (right) from the nonterminal symbol . Nonterminal symbols are blue and terminal symbols are red. In formal language theory, a context-free grammar ( CFG) is a formal grammar whose production rules can ...
In anthropology, high-context culture and low-context culture are ends of a continuum of how explicit the messages exchanged in a culture are and how important the context is in communication. The distinction between cultures with high and low contexts is intended to draw attention to variations in both spoken and non-spoken forms of ...

Context switch. In computing, a context switch is the process of storing the state of a process or thread, so that it can be restored and resume execution at a later point, and then restoring a different, previously saved, state. [1] This allows multiple processes to share a single central processing unit (CPU), and is an essential feature of a ...
A context menu (also called contextual, shortcut, and pop up or pop-up menu) is a menu in a graphical user interface (GUI) that appears upon user interaction, such as a right-click mouse operation. A context menu offers a limited set of choices that are available in the current state, or context, of the operating system or application to which ...
In computer science, in particular in formal language theory, the pumping lemma for context-free languages, also known as the Bar-Hillel lemma, [1] is a lemma that gives a property shared by all context-free languages and generalizes the pumping lemma for regular languages . The pumping lemma can be used to construct a proof by contradiction ...
Context (linguistics) In semiotics, linguistics, sociology and anthropology, context refers to those objects or entities which surround a focal event, in these disciplines typically a communicative event, of some kind. Context is "a frame that surrounds the event and provides resources for its appropriate interpretation".
