Evaluation is a general term for the determination of the "value" of a mathematical expression, a meeting, a procedure, etc., by computation, discussion or analysis.
The reputation of a person, company, etc. is how he, she or it is valued on average, for example with regard to expertise and morality.
Prestige means good reputation or high esteem.

Some programming languages such as the Lisp programming language support expressions as a first-class data type and have an explicit evaluation construct. Other languages such as the C programming language only have expressions as a programming language construct rather than a data type, and implicity evaluate expressions at compile-time or run-time.
For example in LISP the expression
(eval (quote (add 2 3)))
5by calling the evaluator function
evalon the expression
(add 2 3).
