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.

electronic controller
1. An electronic device incorporating vacuum tubes or solid-state devices that are used to control the actions or positions of equipment; for example, a valve operator.
2. An electric controller in which some or all of the basic functions are performed by electron appliances.
electronic cottage
1. A house, usually in the country, equipped with computers, etc. so people can work there without having to travel to a regular company office.
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.
electronic counter, electronic tachometer
1. An instrument that uses electronic elements to count the number of pulses (short durations of electrical current flows) applied to it.
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.
electronic counter-countermeasures, electronic counter countermeasures, ECCM
1. A division of electronic warfare in which actions are taken to ensure friendly, effective use of electromagnetic radiations or wavelengths in spite of an enemy's use of electronic countermeasures.
2. Efforts made to ensure effective use of electromagnetic radiation in spite of the use of countermeasures by an enemy.
3. Retaliatory tactics used to reduce the effectiveness of electronic countermeasures.
electronic countermeasure reconnaissance
Reconnaissance by aircraft equipped with electronic devices capable of locating enemy radar stations, determining their area coverage, and making radarscope recordings for combat mission folders.
electronic countermeasure, ECM, electronic countermeasures; electromagnetic countermeasure, electromagnetic countermeasures, ECM
1. A division of electronic warfare in which actions are taken to interfere with a military enemy's use of the electromagnetic or a range of electromagnetic radiation or waves, used in military air defenses and interceptions.
2. The disruption of the operation of a military enemy's equipment; as by jamming radio or radar signals.
3. A military offensive or defensive tactic or device using electronic and reflecting apparatuses (apparatus or systems allowing certain functions) to reduce the military effectiveness of enemy equipment involving electromagnetic radiation; such as, guidance, radar, communication, or other radio-wave devices.
electronic crime
Any criminal activity involving the use of computers; such as, the illegal transfer of funds from one account to another or the stealing, changing, or erasing of data in an electronic data bank.
electronic crowbar
An electronic switching device generally used in a power supply to divert a fault current from more delicate components until a fuse, circuit breaker, or similar element has time to respond.
electronic curve tracer
A photoelectric tool with a spot of light which automatically traces along an inked line.

It can measure the area within a closed curve or control a cutting torch for duplicating an irregular design.

Electronic Data Interchange, EDI
A method by which two or more autonomous computer systems exchange computer-readable transaction data.

It is possible even when the computers use different operating systems and it is the key factor in achieving automated medical records that can be shared electronically among providers.

electronic data processing, EDP; automatic data processing, data processing, information processing
1. Automatic data processing by electronic means without the use of tabulating cards or punched tapes.
2. The processing data by using equipment which is predominantly electronic in nature; such as, an electronic digital computer in recording, classifying, summarizing, and manipulating data.
3. The use of electronic memories to store, to up-date, and to read information automatically, and using that information in accounting, filing, etc.; including any computerized information system and the equipment used in that system.
4. Any data processing that is done primarily on electronic equipment.

It usually refers to data which is performed and processed on digital computers.

electronic data-processing center, EDP center
A place where automatically operated equipment is kept, including computers, designed to simplify the interpretation and use of data gathered by instrumentation installation or information-collection agencies.
electronic data-processing machine, EDPM
A machine or its mechanism and attachments which are used primarily in or with an electronic data-processing system.
electronic data-processing management science, electronic data processing management science
1. In computer science, a study or occupation that deals with a class of management problems that can be processed with computer programs.
2. The field of computer processing that deals with a class of management problems which can be utilized by a computer system.
electronic data-processing system, electronic data processing system
1. A process consisting of electronic and other equipment that is used for high-speed data procedures.
2. A method used for data processing by means of machines using electronic circuitry at electronic speed, as opposed to electromechanical equipment.
3. Any machine or group of automatically intercommunicating machines that are capable of entering, receiving, sorting, classifying, computing and/or recording alphabetical or numerical accounting or statistical data without the use of tabulating cards.
