Piggyback
Encyclopedia : P : PI : PIG : Piggyback
Piggyback may refer to:
- Piggy-back: the activity of riding on someone's shoulders or back, the way a child might try to ride a pig on a farm for fun.
- in marketing, as a description for using the know-how, brand, capital or other asset of some other company to enter in a market. The piggyback strategy is used to reduce risk, and more established companies can leverage the brand and market reach of a partner to help them very quickly pick up the credibility and awareness needed in new market segments.[Piggyback Marketing]
- in telecommunications, piggyback may be a causal or slang term for multiplexing, particularly when a minor signal is carried on a major one (by subcarriers, for example). It can also refer to two or more people sharing the same login or network connection for pay-per-account internet services. Clandestine use of a neighbor's Wi-Fi network is an increasingly prevalent example of this.[Wi-Fi users piggyback on free signals][Hey Neighbor, Stop Piggybacking on My Wireless (requires registration)]
- in electrical engineering, a piggyback circuit breaker is a double-switch that fits in a single slot in a breaker panel. This is only if they are side-by-side in the same unit — it does not count single half-height units which share a slot. Both are used when a panel has run out of slots, but can still accept the current. The piggyback breaker has two separate outputs, one for each circuit.
- in rail transport, piggyback refers to the practice of carrying trailers, semi-trailers or containers in a train atop a flatcar (intermodal freight transport).
- in optometry / ophthalmology piggybacking refers to the practice of using a smaller, rigid contact lens on top of a larger, soft contact lens for clinical reasons.
- A Canadian Reader's Digest article mentioned one contract piggybacking on another. In this context, it meant the person for whom the contract was negotiated received the exact same benefits (and drawbacks) as the person to whose contract it was tied.
- In the United States, piggybacking can refer to the practice of two cars overtaking a third car by both entering the opposite lane simultaneously. Such behaviour is considered extremely dangerous and is prohibited in several states. Namely, the fact that the second overtaking car blocks the first overtaking car from behind makes aborting the maneoeuvre or taking other evasive action exceedingly difficult.
