electro-, electr-, electri-
(Greek > Latin: electric, electricity; from amber, resembling amber, generated from amber which when rubbed vigorously [as by friction], produced the effect of static electricity)
Electronics in our lives consists of numerous tools
Equipment which we use everyday relies on electronics to function including calculators, car controls, cameras, washing machines, medical scanners, mobile telephones, radar systems, computers; as well as many other applications or devices which are listed in this unit.
2. An electric circuit in which the balance of electrons in a given electric part; such as, a tube, transistor, or amplifier, is disturbed by something other than an applied electric voltage.
3. An electric circuit having at least one element that manipulates the voltage or current in the circuit.
2. A clock in which the timekeeping impulse is provided by the oscillations (alternating current and associated electric and magnetic fields) of a tiny tuning fork attached to an electronic circuit.
2. An electron-tube or transistor circuit which switches one circuit connection rapidly and in sequence or following in an uninterrupted order to many other circuits, without the wear and noise of mechanical switches.
An example is the radial-beam tube, in which a rotating magnetic field causes an electron beam to sweep over one anode after another anode and produces the desired switching actions.
2. An apparatus that receives, processes, and presents information.
The two basic types of computers are analog and digital.
Although generally not regarded as such, the most prevalent computer is the simple mechanical analog computer, in which gears, levers, ratchets, and pawls perform mathematical operations; for example, the speedometer and the watt-hour meter (used to measure accumulated electrical usage).
The general public has become much more aware of the digital computer with the rapid proliferation of the hand-held calculator and a large variety of intelligent devices and especially with exposure to the Internet and the World Wide Web.
2. The sensing sections of tabulating equipment that enable a machine to process the contents of punched cards in a specified procedure.
2. The amount of space in which a target appears to occupy in a radar resolution cell, as it appears to that radar beam.
2. A microprocessor and memory with electronic maps, forming the central part of an engine management system or of subsystems; such as, a fuel injection or ignition system.
2. The control of a machine or condition by electronic devices.
2. An electric controller in which some or all of the basic functions are performed by electron appliances.
2. A situation in which employees use their home computer terminals and communicate with a central office and other workers who are in a regular working environment or with other home employees.
2. An electronic circuit using electron tubes or equivalent devices for counting electric pulses or transient sharp changes in voltage, currents, or some other normally constant quantities in an electronic system.
3. An instrument capable of counting up to several million electrical pulses per second.
