The field of electronics comprises the study and use of systems that operate by controlling the flow of electrons (or other charge carriers,e.g. electron holes) in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is an integral technique in the field of electronics engineering and is equally important in hardware design for computer engineering. All applications of electronics involve the transmission of either information or power. Consumer electronics are electronic devices intended for consumer use. Consumer electronics usually find applications in entertainment, communications and office productivity. Consumer electronics are manufactured throughout the world, although there is a particularly high concentration of manufacturing activity in the Far East. One overriding characteristic of all consumer electronic products is the trend of ever-falling prices. This is driven by gains in manufacturing efficiency and automation, coupled with improvements in semiconductor design.

Gustav Robert Kirchhoff (March 12, 1824 – October 17, 1887) was a German physicist who contributed to the fundamental understanding of electrical circuits, spectroscopy, and the emission of black-body radiation by heated objects. He coined the term "black body" radiation in 1862, and two sets of independent concepts in both circuit theory and thermal emission are named "Kirchhoff's laws" after him. Kirchhoff formulated his circuit laws, which are now ubiquitous in electrical engineering, in 1845, while still a student. He proposed his law of thermal radiation in 1859, and gave a proof in 1861.

Sirius Satellite Radio is one of two satellite radio (SDARS) services operating in the United States and Canada. (XM Radio is the other provider.) Headquartered in New York City, Sirius provides 69 streams (channels) of music and 65 streams of sports, news and entertainment to listeners. Music streams on Sirius carry a wide variety of music genres, broadcasting 24 hours a day, commercial-free. With most Sirius-enabled radios, the user can see the artist and song information on display while listening to the stream.

In electronics, a vacuum tube or thermionic valve, is a device generally used to amplify, switch or otherwise modify, a signal by controlling the movement of electrons in an evacuated space. For most purposes, the vacuum tube has been replaced by the much smaller, less power-hungry, and less expensive transistor, either as a discrete device or in an integrated circuit. However, tubes are still used in specialized applications, such as in high-end audio systems and high power RF transmitters. Cathode ray tubes are still used as a display device in television sets and computer monitors (although they face serious competition from LCD and plasma displays), and magnetrons are the source of microwaves in microwave ovens.  |
