Class D (baseball)
Minor League Baseball (MiLB) is a professional baseball organization below Major League Baseball (MLB), constituted of teams affiliated with MLB clubs. It was founded on September 5, 1901, in response to the growing dominance of the National League (baseball), National League and American League, as the National Association of Professional Baseball Leagues (NAPBL or NA). Minor League Baseball originated as simply the organization of lower tiers of professional baseball in the United States, comprising clubs that lacked the financial means to compete with the National League and later the American League. The association of minor leagues remained independent throughout the early 20th century, protected by agreements with the major leagues to ensure they were compensated when minor-league players were signed by major-league clubs. Later, Minor League Baseball evolved to be constituted entirely of farm team, affiliates of larger clubs, giving young prospects a chance to develop the ...

Class-D Amplifier
A class-D amplifier, or switching amplifier, is an electronic amplifier in which the amplifying devices (transistors, usually MOSFETs) operate as electronic switches, and not as linear gain devices as in other amplifiers. They operate by rapidly switching back and forth between the supply rails, using pulse-width modulation, pulse-density modulation, or related techniques to produce a pulse train output. A simple low-pass filter may be used to attenuate their high-frequency content to provide analog output current and voltage. Little energy is dissipated in the amplifying transistors because they are always either fully on or fully off, so efficiency can exceed 90%. History The first class-D amplifier was invented by British scientist Alec Reeves in the 1950s and was first called by that name in 1955. The first commercial product was a kit module called the X-10 released by Sinclair Radionics in 1964. However, it had an output power of only 2.5 watts. The Sinclair X-20 in ...

Class D Fire Extinguisher
A fire extinguisher is a handheld active fire protection device usually filled with a dry or wet chemical used to extinguish or control small fires, often in emergencies. It is not intended for use on an out-of-control fire, such as one which has reached the ceiling, endangers the user (i.e., no escape route, smoke, explosion hazard, etc.), or otherwise requires the equipment, personnel, resources or expertise of a fire brigade. Typically, a fire extinguisher consists of a hand-held cylindrical pressure vessel containing an #Types of extinguishing agents, agent that can be discharged to extinguish a fire. Fire extinguishers manufactured with non-cylindrical pressure vessels also exist, but are less common. There are two main types of fire extinguishers: stored-pressure and cartridge-operated. In stored-pressure units, the expellant is stored in the same chamber as the firefighting agent itself. Depending on the agent used, different propellants are used. With dry chemical extingu ...

Class D Star
In astronomy, stellar classification is the classification of stars based on their spectral characteristics. Electromagnetic radiation from the star is analyzed by splitting it with a prism or diffraction grating into a spectrum exhibiting the rainbow of colors interspersed with spectral lines. Each line indicates a particular chemical element or molecule, with the line strength indicating the abundance of that element. The strengths of the different spectral lines vary mainly due to the temperature of the photosphere, although in some cases there are true abundance differences. The ''spectral class'' of a star is a short code primarily summarizing the ionization state, giving an objective measure of the photosphere's temperature. Most stars are currently classified under the Morgan–Keenan (MK) system using the letters ''O'', ''B'', ''A'', ''F'', ''G'', ''K'', and ''M'', a sequence from the hottest (''O'' type) to the coolest (''M'' type). Each letter class is then subdivided u ...

Classful Network
A classful network is an obsolete network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. The method divides the IP address space for Internet Protocol version 4 (IPv4) into five address classes based on the leading four address bits. Classes A, B, and C provide unicast addresses for networks of three different network sizes. Class D is for multicast networking and the class E address range is reserved for future or experimental purposes. Since its discontinuation, remnants of classful network concepts have remained in practice only in limited scope in the default configuration parameters of some network software and hardware components, most notably in the default configuration of subnet masks. Background In the original address definition, the most significant eight bits of the 32-bit IPv4 address was the ''network number'' field which specified the particular network a host was attached to. ...

Airspace Class
Airspace class is a category used to divide the sky into different zones, defined by both geographical boundaries and altitude levels. The International Civil Aviation Organization (ICAO) provides standardized airspace classifications that most countries follow. The classification dictates the level of control and services provided to aircraft operating within that airspace. However, nations may choose to implement only certain classes and modify the associated regulations and requirements to suit their needs. Additionally, countries can establish special use airspace (SUA) zones with supplementary regulations to address national security concerns or safety considerations. Abbreviations used in this article ICAO definitions On March 12, 1990, ICAO adopted the current airspace classification scheme. The classes are fundamentally defined in terms of flight rules and interactions between aircraft and air traffic control (ATC). Generally speaking, the ICAO airspaces allocate the r ...

Driver's License In The United States
In the United States, driver's licenses are issued by each individual state, territory, and the District of Columbia (a practical aspect of federalism). Drivers are normally required to obtain a license from their state of residence. All states of the United States and provinces and territories of Canada recognize each other's licenses for non-resident age requirements. There are also licenses for motorcycle use. Generally, a minimum age of 15 is required to apply for a non-commercial driver license, and 18 for commercial licenses which drivers must have to operate vehicles that are too heavy for a non-commercial licensed driver (such as buses, trucks, and tractor-trailers) or vehicles with at least 16 passengers (including the driver) or containing hazardous materials that require placards. A state may also suspend an individual's driving privilege within its borders for traffic violations. Many states share a common system of license classes, with some exceptions, e.g. commer ...
