Prototype
A prototype is an early sample, model, or release of a product built to test a concept or process or to act as a thing to be replicated or learned from. It is a term used in a variety of contexts, including semantics, design, electronics, and software programming. A prototype is designed to test and try a new design to enhance precision by system analysts and users. Prototyping serves to provide specifications for a real, working system rather than a theoretical one. In some workflow models, creating a prototype (a process sometimes called materialization) is the step between the formalization and the evaluation of an idea.
The word prototype derives from the Greek πρωτότυπον prototypon, "primitive form", neutral of πρωτότυπος prototypos, "original, primitive", from πρῶτος protos, "first" and τύπος typos, "impression".
Basic prototype categories
Prototypes explore different aspects of an intended design:
Undeclared
Undeclared is an American sitcom created by Judd Apatow, which aired on Fox during the 2001–02 season. The show has developed a cult following, and in 2012, Entertainment Weekly listed it at #16 in the "25 Best Cult TV Shows from the Past 25 Years".
Premise
The half-hour comedy was Judd Apatow's follow-up to an earlier television series he worked on, Freaks and Geeks, which also lasted for one season. Undeclared centers on a group of college freshmen at the fictional University of Northeastern California. Unlike Freaks, it was set contemporaneously (early 2000s) rather than the 1980s.

Prototype (company)
Prototype Ltd. (株式会社プロトタイプ, Kabushiki kaisha Purototaipu) is a Japanese software company established on March 27, 2006 by Toshio Tabeta, a former producer of Interchannel. While still with Interchannel, Tabeta's team was responsible for mainly developing and publishing versions of visual novels originally published by VisualArt's for consumer platforms like the PlayStation 2 and PlayStation Portable. After Prototype split off from Interchannel, the company still continued to work with VisualArt's. Prototype is also involved in producing mobile phone ports through VisualArt's Motto which Prototype manages. Prototype has also produced a set of drama CDs based on Key's visual novel Clannad.

EPROM
An EPROM (rarely EROM), or erasable programmable read-only memory, is a type of memory chip that retains its data when its power supply is switched off. Computer memory that can retrieve stored data after a power supply has been turned off and back on is called non-volatile. It is an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in digital circuits. Once programmed, an EPROM can be erased by exposing it to strong ultraviolet light source (such as from a mercury-vapor light). EPROMs are easily recognizable by the transparent fused quartz window in the top of the package, through which the silicon chip is visible, and which permits exposure to ultraviolet light during erasing.
Operation
Development of the EPROM memory cell started with investigation of faulty integrated circuits where the gate connections of transistors had broken. Stored charge on these isolated gates changed their properties. The EPROM was invented by Dov Frohman of Intel in 1971, who was awarded US patent 3660819 in 1972.
