cascade (redirected from Cascades)

cascade

A connected series of devices or images. It often implies that the second and subsequent device takes over after the previous one is used up. For example, cascading tapes in a dual-tape backup system means the second tape is written after the first one is full. In a PC, a second IRQ chip is cascaded to the first, doubling the number of interrupts.

1.	(compiler)	cascade - A huge volume of spurious error-messages output by a compiler with poor error recovery. Too frequently, one trivial syntax error (such as a missing ")" or "}") throws the parser out of synch so that much of the remaining program text, whether correct or not, is interpreted as garbaged or ill-formed.
2.	(messaging)	cascade - A chain of Usenet followups, each adding some trivial variation or riposte to the text of the previous one, all of which is reproduced in the new message; an include war in which the object is to create a sort of communal graffito.
3.	(networking)	cascade - A collection of interconneced networking devices, typically hubs, that allows those devices to act together as a logical repeater.
