- computability theory — (mathematics) The area of theoretical computer science concerning what problems can be solved by any computer. A function is computable if an algorithm can be implemented which will give the correct output for any valid input. Since computer programs are countable but real numbers are not, it follows that there must exist real numbers that cannot be calculated by any program. Unfortunately, by definition, there isn't an easy way of describing any of them! In fact, there are many tasks (not just calculating real numbers) that computers cannot perform. The most well-known is the halting problem, the busy beaver problem is less famous but just as fascinating.

- context-free grammar — (grammar) (CFG) A grammar where the syntax of each constituent (syntactic category or terminal symbol) is independent of the symbols occuring before and after it in a sentence. A context-free grammar describes a context-free language. Context-free grammars can be expressed by a set of "production rules" or syntactic rules. For example, a language with symbols "a" and "b" that must occur in unequal numbers can be represented by the CFG: S → U | V U → TaU | TaT | UaT V → TbV | TbT | VbT T → aTbT | bTaT | ε meaning the top-level category "S" consists of either a "U" or a "V" and so on. The special category "ε" represents the empty string. This grammar is context-free because each rule has a single symbol on its left-hand side.
