Input (computer science)         
IN COMPUTING, INPUT OF A PROGRAM OR PROCESS, I.E. A COMMAND OR SIGNAL FROM OUTER SOURCES
Data input
In computer science, the general meaning of input is to provide or give something to the computer, in other words, when a computer or device is receiving a command or signal from outer sources, the event is referred to as input to the device.

  • Pinacol rearrangement
REARRANGEMENT OF A 1,2-DIOL COMPOUND TO CARBONYL COMPOUND
Pinacol–pinacolone rearrangement; Pinacol-pinacolone rearrangement; Pinnacol–pinnacolone rearrangement; Pinnacol-pinnacolone rearrangement
The pinacol–pinacolone rearrangement is a method for converting a 1,2-diol to a carbonyl compound in organic chemistry. The 1,2-rearrangement takes place under acidic conditions.

In economics, an input–output model is a quantitative economic model that represents the interdependencies between different sectors of a national economy or different regional economies.Thijs Ten Raa, Input–Output Economics: Theory and Applications: Featuring Asian Economies, World Scientific, 2009 Wassily Leontief (1906–1999) is credited with developing this type of analysis and earned the Nobel Prize in Economics for his development of this model.

Hofmann–Martius rearrangement

The Hofmann–Martius rearrangement in organic chemistry is a rearrangement reaction converting an N-alkylated aniline to the corresponding ortho and / or para aryl-alkylated aniline. The reaction requires heat, and the catalyst is an acid like hydrochloric acid.

When the catalyst is a metal halide the reaction is also called the Reilly–Hickinbottom rearrangement.

The reaction is also known to work for aryl ethers and two conceptually related reactions are the Fries rearrangement and the Fischer–Hepp rearrangement. Its reaction mechanism centers around dissociation of the reactant with the positively charged organic residue R attacking the aniline ring in a Friedel–Crafts alkylation.

In one study this rearrangement was applied to a 3-N(CH3)(C6H5)-2-oxindole:

The reaction is named after German chemists August Wilhelm von Hofmann and Carl Alexander von Martius.
