Software is a program that enables a computer to perform a specific task, as opposed to the physical components of the system (hardware). This includes application software such as a word processor, which enables a user to perform a task, and system software such as an operating system, which enables other software to run properly, by interfacing with hardware and with other software. Software also acts as an interface between the hardware like processor(s) and user(s).

Simulation software is based on the process of modeling a real phenomenon with a set of mathematical formulas. It is, essentially, a program that allows the user to observe an operation through simulation without actually performing that operation. Simulation software is used widely to design equipment so that the final product will be as close to design specs as possible without expensive in process modification. Simulation software with real-time response is often used in gaming, but it also has important industrial applications. When the penalty for improper operation is costly, such as airplane pilots, nuclear power plant operators, or chemical plant operators, a mock up of the actual control panel is connected to a real-time simulation of the physical response, giving valuable training experience without fear of a disastrous outcome.

Advanced computer programs can simulate weather conditions, electronic circuits, chemical reactions, mechatronics, heat pumps, feedback control systems, atomic reactions, even biological processes. In theory, any phenomena that can be reduced to mathematical data and equations can be simulated on a computer. Simulation can be difficult because most natural phenomena are subject to an almost infinite number of influences. One of the tricks to developing useful simulations is to determine which are the most important factors that affect the goals of the simulation.

In addition to imitating processes to see how they behave under different conditions, simulations are also used to test new theories. After creating a theory of causal relationships, the theorist can codify the relationships in the form of a computer program. If the program then behaves in the same way as the real process, there is a good chance that the proposed relationships are correct.

Bill Gates, 16. November 2004 at IT-Forum in Copenhagen
'William Henry Gates III
'
William Henry Gates III, (b. October 28, 1955), commonly known as Bill Gates is the founder, chairman, former chief software architect, and former CEO of Microsoft. He is consistently ranked in the Forbes list of the world's wealthiest people. Between 2009 and 2014 his wealth more than doubled from $40 billion to more than $82 billion. When family wealth is considered, his family ranks second behind the Walton family. Gates is the first one to reach the richest peak from the technology world.

Gates is a leading philanthropist, and has stated that he intends to give away the majority of his vast wealth. He and his wife set up the Bill & Melinda Gates Foundation (B&MGF) in 1994 with the aim of improving health and combating poverty in developing regions across the world. He has attracted considerable acclaim for the Foundation's work, including its work in combating HIV infection in Africa.

Gates finally quit day-to-day responsibility at Microsoft in June 2008 in favour of running the B&MGF after a long period of moving away from executive control, originally as CEO, then as 'Chief Software Architect'. Gates remains chairman of Microsoft.

Selected quote

" This existing base of FLOSS software represents a lower bound of about 131,000 real person-years of effort that has been devoted exclusively by programmers. As this is mostly by individuals not directly paid for development, it represents a significant gap in national accounts of productivity. Annualised and adjusted for growth this represents at least 800 million euros in voluntary contribution from programmers alone each year, of which nearly half are based in Europe. "

(Note: FLOSS is an acronym for "free, libre and open source software".)
