In telecommunications, a scrambler is a device that transposes or inverts signals or otherwise encodes a message at the transmitter to make the message unintelligible at a receiver not equipped with an appropriately set descrambling device. Whereas encryption usually refers to operations carried out in the digital domain, scrambling usually refers to operations carried out in the analog domain. Scrambling is accomplished by the addition of components to the original signal or the changing of some important component of the original signal in order to make extraction of the original signal difficult. Examples of the latter might include removing or changing vertical or horizontal sync pulses in television signals; televisions will not be able to display a picture from such a signal. Some modern scramblers are actually encryption devices, the name remaining due to the similarities in use, as opposed to internal operation.
In telecommunications and recording, a scrambler (also referred to as a randomizer) is a device that manipulates a data stream before transmitting. The manipulations are reversed by a descrambler at the receiving side. Scrambling is widely used in satellite, radio relay communications and PSTN modems. A scrambler can be placed just before a FEC coder, or it can be placed after the FEC, just before the modulation or line code. A scrambler in this context has nothing to do with encrypting, as the intent is not to render the message unintelligible, but to give the transmitted data useful engineering properties.
Scrambler (Kim Il Sung) is a fictional mutant character in the Marvel Comics Universe. He first appeared in Uncanny X-Men #210 and was created by Chris Claremont, John Romita Jr and Dan Green.
Scrambler is a mutant and a sociopath, and a member of the Marauders, a band of assassins who were gathered together by the mutant thief Gambit at the request of the enigmatic mastermind known as Mister Sinister.
Sinister first sent the Marauders to murder the entire population of the underground mutant community known as the Morlocks. In the course of this mutant massacre, the Marauders clashed with the mutant adventurers known as the X-Men and the original X-Factor team. Subsequently, the X-Men thwarted the Marauders' attempt to assassinate Sinister's former pawn, Madelyne Pryor, in San Francisco.
Later, Sinister sent the Marauders to battle the X-Men during the time of the demonic invasion of New York City known as the "Inferno". The Marauders were all killed during the "Inferno", but Sinister possesses the ability to clone them thanks to samples of their DNA. The Marauders later clashed with the dimensionally-displaced young mutant known as Nate Grey after they attempted to assassinate Sinister's former servant, Threnody.
There are many systems for classifying types of motorcycles, describing how the motorcycles are put to use, or the designer's intent, or some combination of the two. Six main categories are widely recognized: cruiser, sport, touring, standard, dual-purpose, and dirt bike. Sometimes sport touring motorcycles are recognized as a seventh category. Strong lines are sometimes drawn between motorcycles and their smaller cousins, mopeds, scooters, and underbones, but other classification schemes include these as types of motorcycles.
There is no universal system for classifying all types of motorcycles. There are strict classification systems enforced by competitive motorcycle sport sanctioning bodies, or legal definitions of a motorcycle established by certain legal jurisdictions for motorcycle registration, emissions, road traffic safety rules or motorcyclist licensing. There are also informal classifications or nicknames used by manufacturers, riders, and the motorcycling media. Some experts do not recognize sub-types, like naked bike, that "purport to be classified" outside the six usual classes, because they fit within one of the main types and are recognizable only by cosmetic changes.
