"End-of-life" (EOL) is a term used with respect to a product supplied to customers, indicating that the product is in the end of its useful life (from the vendor's point of view), and a vendor stops marketing, selling, or rework sustaining it.

(The vendor may simply intend to limit or end support for the product) In the specific case of product sales, a vendor may employ the more specific term "end-of-sale" (EOS).

The time-frame after the last production date depends on the product and relates to the expected product lifetime from a customer's point of view.

Different lifetime examples include toys from fast food chains (weeks or months), cars (10 years), and mobile phones (3 years).

Semiconductors are crystalline or amorphous solids with distinct electrical characteristics.

They are of high electrical resistance — higher than typical resistance materials, but still of much lower resistance than insulators.

Their resistance decreases as their temperature increases, which is behavior opposite to that of a metal.

Finally, their conducting properties may be altered in useful ways by the deliberate, controlled introduction of impurities ("doping") into the crystal structure, which lowers its resistance but also permits the creation of semiconductor junctions between differently-doped regions of the extrinsic semiconductor crystal.

The behavior of charge carriers which include electrons, ions and electron holes at these junctions is the basis of diodes, transistors and all modern electronics.

Electronics is the science of controlling electrical energy electrically, in which the electrons have a fundamental role.

Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes, integrated circuits, associated passive electrical components, and interconnection technologies.

Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.

American English (variously abbreviated AmE, AE, AmEng, USEng, en-US), also called United States English or U.S. English, is the set of varieties of the English language native to the United States and widely adopted in Canada.

English is the most widely spoken language in the United States and is the common language used by the federal government, considered the de facto language of the country because of its widespread use.

English has been given official status by 32 of the 50 state governments.

As an example, while both Spanish and English have equivalent status in the local courts of Puerto Rico, under federal law, English is the official language for any matters being referred to the United States district court for the territory.

Rochester (or) is a city on the southern shore of Lake Ontario in the western portion of the U.S. state of New York, and the seat of Monroe County.
