The invention of transistors revolutionized human civilization like no other technology. This video demonstrates working of a Bipolar Junction Transistor (BJT) with its practical applications such as transistor as an amplifier and as a switch with help of animation. Along with transistor working of diode is also explained in the video. The video covers following topics — structure of Silicon atom, doping, N type doping, P type doping, working of Diode, working of NPN transistor and dual stage amplification.
How does a transistor work? Our lives depend on this device.

When I mentioned to people that I was doing a video on transistors, they would say «as in a transistor radio?» Yes! Thats exactly what I mean, but it goes so much deeper than that. After the transistor was invented in 1947 one of the first available consumer technologies it was applied to was radios, so they could be made portable and higher quality. Hence the line in Brown-eyed Girl — «going down to the old mine with a transistor radio.»
But more important to our lives today, the transistor made possible the microcomputer revolution, and hence the Internet, and also TVs, mobile phones, fancy washing machines, dishwashers, calculators, satellites, projectors etc. etc. A transistor is based on semiconductor material, usually silicon, which is doped with impurities to carefully change its electrical properties. These n and p-type semiconductors are then put together in different configurations to achieve a desired electrical result. And in the case of the transistor, this is to make a tiny electrical switch. These switches are then connected together to perform computations, store information, and basically make everything electrical work intelligently.

В этом видео распакуем SSD диск на 480 гигабайта, производителя Goldenfir, проверим скорость чтения и записи, глянем на запуск игр и затронем другие не менее важные темы.
Этот SSD диск можно установить как в ноутбук, так и в компьютер. Обучающий урок на эту тему запишу в ближайшее время :)
