carrier definition by American Heritage Dictionary
- One that transports or conveys: baggage carriers; a message carrier.
- One, such as a person, business, or organization, that deals in the transport of passengers or goods.
- A mechanism or device by which something is conveyed or conducted.
- Medicine A person or an animal that shows no symptoms of a disease but harbors the infectious agent of that disease and is capable of transmitting it to others.
- Genetics An individual that carries one gene for a particular recessive trait. A carrier does not express the trait but, when mated with another carrier, can produce offspring that do.
- Electronics a. A carrier wave.b. A charge-carrying entity, especially an electron or a hole in a semiconductor.
- An aircraft carrier.
- An insurance or underwriting organization.
- A telecommunications company.
carrier - Business Definition
- An insurance company that underwrites (carries the risk) and issues an insurance policy
- See common carrier.
carrier - Computer Definition
- A continuous signal, or waveform, at a certain frequency on a circuit, or within a certain frequency range, and that can be modulated to support an information-bearing signal. In other words, the carrier carries the information signal, which the transmitter impresses on the carrier by varying the signal in some fashion. The carrier also can support signaling and control information used to coordinate and manage various aspects of network operations, although signaling and control can also occur over a subcarrier frequency. A carrier also is known as a carrier wave.
- A company that provides information transport services. For example, a Local Exchange Carrier (LEC) provides local information transport services, and an Interexchange Carrier (IEC or IXC) provides transport services between LECs. A heavy carrier is facilities-based, i.e., owns the switching and transmission systems that comprise the network it uses to provide services to its customers.A light carrier is not facilities-based, i.e., leases rather than owns the network it uses to provide services.A common carrier provides message transport services to the general public and generally is regulated to a considerable extent, at least with respect to fundamental aspects of service such as availability and basic rates. See also common carrier, IXC, and LEC.
(2) A waveform that has a fixed center frequency. It is used to contain data and establish a unique channel that can be identified independently of other channels. Carriers are the primary method used to send wireless signals over the air in order to differentiate between transmitting stations. For example, AM and FM radio, TV, satellite and Wi-Fi all use carriers. In fact, AM and FM radio actually use the carrier frequency as their station's channel number. Multiple Carriers - Multiple Data Streams Carriers are also used to transmit multiple channels simultaneously within a wire or fiber. For example, several voice, data and video signals can travel over the same line, each residing in its own carrier vibrating at a different frequency. See definition #2 in broadband. Multiple Carriers - One Data Stream Instead of sending a separate stream of data in each carrier, multiple carriers can be used for only one channel of data. For example, the widely used orthogonal frequency division multiplexing (OFDM) method uses numerous subcarriers for only one transmitting channel and one stream of data (see OFDM). See modulation and subcarrier.
carrier - Legal Definition
carrier - Medical Definition
- A person or an animal that shows no symptoms of a disease but harbors the infectious agent of that disease and is capable of transmitting it to others.
- A compound capable of transferring a hydrogen atom from one compound to another.
- A quantity of naturally occurring element added to a minute amount of pure isotope, especially a radioactive one, to facilitate the chemical handling of the isotope.
- An individual that carries, but does not express, a gene for a particular recessive trait, yet when mated with another carrier, can produce offspring that do.
carrier - Science Definition
- A person, animal, or plant that serves as a host for a pathogen and can transmit it to others, but is immune to it. Mosquitoes are carriers of malaria.
- An organism that carries a gene for a trait but does not show the trait itself. Carriers can produce offspring that express the trait by mating with another carrier of the same gene. See more at recessive.
