Whois & Analysis for railpictures.net

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".

Rail transport is a means of conveyance of passengers and goods on wheeled vehicles running on rails, also known as tracks.

It is also commonly referred to as train transport.

In contrast to road transport, where vehicles run on a prepared flat surface, rail vehicles (rolling stock) are directionally guided by the tracks on which they run.

Tracks usually consist of steel rails, installed on ties (sleepers) and ballast, on which the rolling stock, usually fitted with metal wheels, moves.

Other variations are also possible, such as slab track, where the rails are fastened to a concrete foundation resting on a prepared subsurface.

The Internet is the global system of interconnected computer networks that use the Internet protocol suite (TCP/IP) to link devices worldwide.

It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies.

The Internet carries an extensive range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and peer-to-peer networks for file sharing.

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.

An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages.

They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived.

Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes visible.
