29Callback (computer science) — In computer programming, a callback is executable code that is passed as an argument to other code. It allows a lower level software layer to call a subroutine (or function) defined in a higher level layer. Usually, the higher level code starts… …
30Layered clothing — is a manner of dressing using multiple garments that are worn on top of each other. Some of the layers have different, largely non overlapping, functions. Using more or fewer layers, or replacing one layer but not others, allows for flexible… …
