Electronics is the discipline dealing with the development and application of devices and systems involving the flow of electrons in a vacuum, in gaseous media, and in semiconductors.
The FM broadcast band, used for FM broadcast radio by radio stations, differs between different parts of the world.
Frequency is the number of occurrences of a repeating event per unit of time.
In computer networking, Gigabit Ethernet (GbE or 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of a gigabit per second (1,000,000,000 bits per second), as defined by the IEEE 802.3-2008 standard.
Half-life (symbol t1⁄2) is the time required for a quantity to reduce to half its initial value.
The hertz (symbol: Hz) is the derived unit of frequency in the International System of Units (SI) and is defined as one cycle per second.
The International Bureau of Weights and Measures (Bureau international des poids et mesures) is an intergovernmental organization established by the Metre Convention, through which Member States act together on matters related to measurement science and measurement standards.
The International System of Units (SI, abbreviated from the French Système international (d'unités)) is the modern form of the metric system, and is the most widely used system of measurement.
The international yard and pound are two units of measurement that were the subject of an agreement among representatives of six nations signed on 1 July 1959, namely the United States, United Kingdom, Canada, Australia, New Zealand and South Africa.
In computer networking, a minimal pause may be required between network packets or network frames.
Beryllium (4Be) has 12 known isotopes, but only one of these isotopes is stable and a primordial nuclide.
Carbon (6C) has 15 known isotopes, from 8C to 22C, of which 12C and 13C are stable.
Naturally occurring lithium (3Li) is composed of two stable isotopes, lithium-6 and lithium-7, with the latter being far more abundant: about 92.5 percent of the atoms.
Polonium (84Po) has 33 isotopes, all of which are radioactive, with between 186 and 227 nucleons.
Jiffy is an informal term for any unspecified short period of time, as in "I will be back in a jiffy".
In particle physics, a kaon, also called a K meson and denoted,The positively charged kaon used to be called τ+ and θ+, as it was supposed to be two different particles until the 1960s.
A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
Light is electromagnetic radiation within a certain portion of the electromagnetic spectrum.
An unusual unit of measurement is a unit of measurement that does not form part of a coherent system of measurement; especially in that its exact quantity may not be well known or that it may be an inconvenient multiple or fraction of base units in such systems.
Medium wave (MW) is the part of the medium frequency (MF) radio band used mainly for AM radio broadcasting.
The metre (British spelling and BIPM spelling) or meter (American spelling) (from the French unit mètre, from the Greek noun μέτρον, "measure") is the base unit of length in some metric systems, including the International System of Units (SI).
A metric prefix is a unit prefix that precedes a basic unit of measure to indicate a multiple or fraction of the unit.
A microsecond is an SI unit of time equal to one millionth (0.000001 or 10−6 or 1/1,000,000) of a second.
A millisecond (from milli- and second; symbol: ms) is a thousandth (0.001 or 10−3 or 1/1000) of a second.
The minute is a unit of time or angle.
Nathaniel David Mermin (born 1935) is a solid-state physicist at Cornell University best known for the eponymous Mermin–Wagner theorem, his application of the term "boojum" to superfluidity, his textbook with Neil Ashcroft on solid-state physics, and for contributions to the foundations of quantum mechanics and quantum information science.
Nano- (symbol n) is a unit prefix meaning "one billionth".
The following are examples of orders of magnitude for different lengths.
An order of magnitude of time is (usually) a decimal prefix or decimal order-of-magnitude quantity together with a base unit of time, like a microsecond or a million years.
In quantum computing, and more specifically in superconducting quantum computing, the phase qubit is a superconducting device based on the superconductor-insulator-superconductor (SIS) Josephson junction, designed to operate as a quantum bit, or qubit.
A picosecond is an SI unit of time equal to 10−12 or 1/1,000,000,000,000 (one trillionth) of a second.
In quantum computing, a qubit or quantum bit (sometimes qbit) is a unit of quantum information—the quantum analogue of the classical binary bit.
A radiotelephone (or radiophone) is a communications system for transmission of speech over radio.
The second is the SI base unit of time, commonly understood and historically defined as 1/86,400 of a day – this factor derived from the division of the day first into 24 hours, then to 60 minutes and finally to 60 seconds each.
A shake is an informal unit of time equal to 10 nanoseconds, or 10−8 seconds.
Shortwave radio is radio transmission using shortwave radio frequencies.
Telecommunication is the transmission of signs, signals, messages, words, writings, images and sounds or information of any nature by wire, radio, optical or other electromagnetic systems.
A thermonuclear weapon is a second-generation nuclear weapon design using a secondary nuclear fusion stage consisting of implosion tamper, fusion fuel, and spark plug which is bombarded by the energy released by the detonation of a primary fission bomb within, compressing the fuel material (tritium, deuterium or lithium deuteride) and causing a fusion reaction.
In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats.
40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates of 40 and 100 gigabits per second (Gbit/s), respectively.
