The FIM Road Racing World Championship Grand Prix is the premier class of motorcycle road racing, held since 1949.

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal (a time-varying voltage or current).

An amplifier functions by taking power from a power supply and controlling the output to match the input signal shape but with a larger amplitude.

In this sense, an amplifier modulates the output of the power supply based upon the properties of the input signal.

An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss.

Information is that which informs.

In other words, it is the answer to a question of some kind.

It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts.

As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.

A photograph or photo is an image created by light falling on a light-sensitive surface, usually photographic film or an electronic medium such as a CCD or a CMOS chip.

Most photographs are created using a camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would see.

The process and practice of creating photographs is called photography.

The word "photograph" was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (phos), meaning "light", and γραφή (graphê), meaning "drawing, writing", together meaning "drawing with light".

Videotape is magnetic tape used for storing video and usually sound in addition.

Information stored can be in the form of either an analog signal or digital signal.

Videotape is used in both video tape recorders (VTRs) or, more commonly, videocassette recorders (VCRs) and camcorders.

Videotapes are also used for storing scientific or medical data, such as the data produced by an electrocardiogram.
