	Virtual (horse) Virtual (foaled 10 May 2005) is a thoroughbred racehorse who won the Lockinge Stakes at Newbury in 2009. Virtual is a bay horse who was sired by Pivotal out of Virtuous. He was bred and owned by Cheveley Park Stud and trained by John Gosden at Newmarket, Suffolk. He ran fourteen times in a career that lasted from September 2007 to October 2009 and won five times. He gained his most important win in the 2009 Lockinge Stakes when he beat Alexandros by a nose, ridden by Jimmy Fortune Jimmy Fortune (born March 11, 1955) is an American country music singer from Nelson County, Virginia. Fortune sang tenor for The Statler Brothers for 21 years, and wrote the song "Elizabeth" for the group. After The Statler Brothers retired, he c ....

	Virtual Channel In most telecommunications organizations, a virtual channel is a method of remapping the ''program number'' as used in H.222 Program Association Tables and Program Mapping Tables to a channel number that can be entered via digits on a receiver's remote control. Often, "virtual channels" are implemented in digital television, helping users to find a desired channel easily, or easing the transition from analogue to digital broadcasting in general. The practice of assigning virtual channels is most common in those parts of the world where TV stations were colloquially named after the RF channel they were transmitting on ("Channel 6 Springfield"), as it was common in North America during the analogue TV era. In other parts of the world, such as Europe, virtual channels are rarely used or needed, as TV stations there identify themselves by name, not by RF channel or callsign. A "virtual channel" was first used for DigiCipher 2 in North America. It was later used and referred to as a l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Virtual Function In object-oriented programming, in languages such as C++, and Object Pascal, a virtual function or virtual method is an inheritable and overridable function or method for which dynamic dispatch is facilitated. This concept is an important part of the (runtime) polymorphism portion of object-oriented programming (OOP). In short, a virtual function defines a target function to be executed, but the target might not be known at compile time. Most programming languages, such as JavaScript, PHP and Python, treat all methods as virtual by default and do not provide a modifier to change this behavior. However, some languages provide modifiers to prevent methods from being overridden by derived classes (such as the ''final'' keyword in Java and PHP). Purpose The concept of the virtual function solves the following problem: In object-oriented programming, when a derived class inherits from a base class, an object of the derived class may be referred to via a pointer or reference of ...
