Electronics

Electronics is the branch of physics that deals with the emission and effects of electrons and with the use of electronic devices and effects of electrons to develop components, devices, systems, or equipment that uses electricity as part of its driving force. Main areas of usage of electronics are modern information technology and telecommunications, tools for recording and playing sound and picture, sensors and steering systems, instrumentation and measurement devices. Modern electronics has revolutionized medical diagnosis by introducing new techniques like CT (computer tomography), MR (magnetic resonance), and ultrasound imaging devices.
