All very logical

RIXLUTS1bComputers do many wonderful things: from running medical equipment and scientific simulations to searching the web and playing music or games. Yet all these different computer applications ultimately boil down to straightforward mathematical operations: adding or multiplying two numbers together, checking to see which of two numbers is the largest, and so on. This maths is performed by electrical circuits made up of logic gates. Logic gates are small electrical components that each perform a simple job, but can be built up in circuits to do very complicated processes.
