These textbooks were written by Tony R. Kuphaldt. This site provides a series of online textbooks covering electricity and electronics. The information provided is great for both students and hobbyists who are looking to expand their knowledge in this field. Do you need, as a programmer, this kind of knowledge? If your goal is to be a good programmer, yes, you do! A machine is a collection of digital circuits. A digital circuit is often constructed from small electronic circuits called logic gates ( logic gates are the components involved in operations as additions, subtractions, and so on. A machine has not any brain or mind! The only brains involved in information technology are the engineers and programmers brains. We have to learn to give the devil his due! ). Each logic gate represents a function of boolean logic. A logic gate is an arrangement of electrically controlled switches. The output of a logic gate is an electrical flow or voltage, that can, in turn, control more logic gates. Logic gates often use the fewest number of transistors in order to reduce their size, power consumption and cost, and increase their reliability. Integrated circuits are the least expensive way to make logic gates in large volumes. Integrated circuits are usually designed by engineers using electronic design automation software. In order to send instructions to electronic components, a programmer has to know these components and their architecture, designed by engineers. In this site, you'll find also a great video lessons section too about: Electronic Systems, Basic Electronics and Units of Measure, Basic Components ( Wire and Cable, Voltage sources, Resistors, Capacitors, Inductors, and so on ) and Technical Notation, Circuits, Alternating Current, Semiconductor Technology, Diodes and Diode Circuits, Transistors and Transistor Circuits, Digital and Microprocessors.
