A transceiver is a device that has a transmitter and receiver which is combined into a one unit. The term originates around WWII. Technically, transceiver must combine a significant amount of the transmitter and receiver handling circuitry. In communications and information processing, a transmitter (sometimes abbreviated XMTR) is an object (source) which sends information to an observer (receiver). ... The word receiver has a number of different meanings: In communications and information processing, a receiver is the recipient (observer) of a message (information), which is sent from a source (object). ...

Electronics

In electronics, the term transceiver refers to a device which combines both transmission and reception capabilities within a single housing. The term is used for semiconductor devices designed to send and receive digital data over a line or cable. Electronics is the study and use of electrical devices that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. ...

Computer networks

In computer networking, the term transceiver (sometimes abbreviated to TCVR) is a device that performs, within one chassis, both transmitting and receiving functions that is in a common housing, sometimes designed for portable or mobile use, uses common circuit components for both transmitting and receiving which provides half-duplex operation. A computer network is a system for communication among two or more computers. ... There are many kinds of circuit An electric circuit interconnects electrical elements. ...

Radio technology

In radio terminology, a transceiver means a unit which contains both a receiver and a transmitter. It was quite common to have these units separated. Ham Radio amateurs can build their own equipment and it is always easier to design and build a simple unit having one of the functions, transmitting or receiving. Almost every modern amateur radio equipment is now a transceiver but there is an active market for pure radio receivers, mainly for SWL operators. An example of a transceiver would be a walkie-talkie, or a CB radio. Amateur radio, commonly called ham radio, is a hobby enjoyed by many people throughout the world (as of 2004 about 3 million worldwide, 60,000 in UK, 70,000 in Germany, 5,000 in Norway, 57,000 in Canada, and 700,000 in the USA). ... A sister hobby to amateur radio where the operator only uses a receiver to monitor HF transmissions. ... A walkie-talkie is a portable, bi-directional radio transceiver, first developed for military use. ... Citizens band radio (CB) is, in the United States, a system of short distance radio communication between individuals on a selection of 40 channels within the single 27 MHz (11 meter) band. ...
