ответить на вопросы! текст hundreds of electronic devices are now used for scientific, industrial and everyday purposes. they help to do jobs better or more rationally than before and take over jobs that couldn't be done otherwise. so, industrial electronics undoubtedly plays a very important role today. you can easily ind many electronic devices at home: a cd player, a tv set, an mp3 player, a computer and many others the application and use of electronic devices demand good knowledge of their fundamentas in meters and lamps, clectricity flows in the wire. but inside any transistor or microchlp (and previoushy in radio tubes), electric current passes through the space (or semiconductor) separating certain parts in this unit. such action is called clectronic. it's not difficult to imagine it because the same happens in lightning. there you actually see how electricity jumps through space. the firt electronic equipment used radio lamps. they were: a radico set, a tv set, computing machines (predecessors of modern calculators), computers (which occupied big rooms), tape recorden the next stage came when transistors were invented. the devices became more powerful and much smaller. the number of devices increased greatly, some multifunctional devices appeared (radio + tape recorder). computers and calculators became smaller cassette recorders and video- cassette recorders appcared. the next period was the period of microchips. they helped to reduce big parts of devices, computers and other devices the latest period of industrial electronics development is the period of total digitization of all electronic devices, making them compatible with the computcr. photos are no longer made on film but on memory cards, cassettes and video cassettes are out of use. television is also becoming digital industrial electronics is a great part of our leisure time, it makes people's lives easier and reduces their working time вопросы 1.for what purposes are electronic devices used now? what do they help us to do? 2. industrial electronics plays an important role today, doesn't it? 3. what electronic devices are usually found at home? what can you ind at home? 4. what is the difference between electric and electronic devices? 5. where do you actually see how clectricity jumps through space? 6. what were the first electronic devices based on? 7. did the first computers look like modern ones? 8. did the next stage come when transistons or casettes were inventod? 9. why did computers become smaller when microchips were introduced? 10. what is the latest period of the industrial electronics development called? i1. what devices became compatible with the computer? 12. what does electronics mean in our life? 13. do you think that electronics does only good to people? 14. what will be the next period of the industrial electronics development, in your opinion?
