Electronics is the science of how to control electric energy, energy in which the electrons have a fundamental role. Electronics deals with electrical circuits that involve active electrical components such as vacuum tubes, transistors, diodes and integrated circuits, and associated passive electrical components and interconnection technologies. Commonly, electronic devices contain circuitry consisting primarily or exclusively of active semiconductors supplemented with passive elements; such a circuit is described as an electronic circuit.
Mechatronics and Robotics
A robot is a good example of a mechatronic system. Most robots integrate software, electronics, and mechanical designs in a synergistic manner (meaning that the separate parts act together in such a way that the combined effect is stronger than the sum of the separate effects of each one of the components). Other examples of mechatronics are the digital thermostat and the anti-lock brake system. Both were originally designed as mechanical systems and have been improved later by their integration with electronic controls and digital computing elements.
Software is any set of machine-readable instructions that directs a computer’s processor to perform specific operations. Computer software contrasts with computer hardware, which is the physical component of computers Computer hardware and software require each other and neither can be realistically used without the other. Using a musical analogy, hardware is like a musical instrument and software is like the notes played on that instrument. Computer software includes computer programs, libraries and their associated documentation.
Very-large-scale integration (VLSI) is the process of creating an integrated circuit (IC) by combining thousands of transistors into a single chip. VLSI began in the 1970s when complex semiconductor and communication technologies were being developed. The microprocessor is a VLSI device. Before the introduction of VLSI technology most ICs had a limited set of functions they could perform. An electronic circuit might consist of a CPU, ROM, RAM and other glue logic. VLSI lets IC designers add all of these into one chip. Structured VLSI design is a modular methodology and for saving microchip area by minimizing the interconnect fabrics area.
Communication is the two way process in which the sender transfer the data to a receiver through a medium Communication in electronics includes the wide range of responsibilities and actions relating to: Electronic devices and systems used in the transfer of ideas and perceptions Electronic sensors and sensory systems used in the acquisition of information devoid of semantic influence, Electronic devices and systems intended to allow friendly forces to operate in hostile environments and to deny to hostile forces the effective use of electromagnetic resources.
Electrical engineering is a field of engineering that generally deals with the study and application of electricity, electronics, and electromagnetism. This field first became an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electric power distribution and use. Subsequently, broadcasting and recording media made electronics part of daily life. The invention of the transistor, and later the integrated circuit, brought down the cost of electronics to the point where they can be used in almost any household object.
Simulation is the imitation of the operation of a real-world process or system over time.The act of simulating something first requires that a model be developed; this model represents the key characteristics or behaviors/functions of the selected physical or abstract system or process. The model represents the system itself, whereas the simulation represents the operation of the system over time. Simulation is used in many contexts, such as simulation of technology for performance optimization, safety engineering, testing, training, education, and video games.
