Electronics

The field of electronics comprises the study and use of systems that operate by controlling the flow of electrons (or other charge carriers) in devices such as vacuum tubes and semiconductors. The design and construction of electronic circuits to solve practical problems is an integral technique in the field of electronics engineering and is equally important in hardware design for computer engineering. All applications of electronics involve the transmission of either information or power. Most deal only with information.
The study of new semiconductor devices and surrounding technology is sometimes considered a branch of physics. This article focuses on engineering aspects of electronics. Other important topics include electronic waste and occupational health impacts of semiconductor manufacturing.
In our modern technological society, we are surrounded by electronics equipment. Many of the things we rely on every day, from automobiles to cellular phones, are associated with electronic devices. In the future, electronic devices will likely become smaller and more discrete. We may even see the day when electronic devices are incorporated into the human body, to compensate for a defective function. For example, someday, instead of carrying a MP3 player, a person may be able to have one surgically implanted into his body with the sound going directly into his ears.
Elektronika
Elektronika sohasi vakuum naychalari va yarimo'tkazgichlar kabi qurilmalarda elektronlar (yoki boshqa zaryad tashuvchilar) oqimini boshqarish orqali ishlaydigan tizimlarni o'rganish va ulardan foydalanishni o'z ichiga oladi. Amaliy masalalarni hal qilish uchun elektron sxemalarni loyihalash va qurish elektron muhandislik sohasidagi ajralmas texnikadir va kompyuter muhandisligi uchun apparatni loyihalashda bir xil darajada muhimdir. Elektronikaning barcha ilovalari ma'lumot yoki quvvatni uzatishni o'z ichiga oladi. Ko'pchilik faqat ma'lumot bilan shug'ullanadi.Yangi yarimo'tkazgich qurilmalari va uning atrofidagi texnologiyani o'rganish ba'zan fizikaning bir bo'limi hisoblanadi. Ushbu maqola elektronikaning muhandislik jihatlariga qaratilgan. Boshqa muhim mavzular orasida elektron chiqindilar va yarimo'tkazgichlar ishlab chiqarishning mehnat salomatligiga ta'siri kiradi.
Bizning zamonaviy texnologik jamiyatimizda biz elektronika uskunalari bilan o'ralganmiz. Biz har kuni tayanadigan narsalarning ko'pchiligi, avtomobillardan tortib uyali telefonlargacha, elektron qurilmalar bilan bog'liq. Kelajakda elektron qurilmalar kichikroq va diskret bo'lishi mumkin. Hatto nuqsonli funktsiyani qoplash uchun inson tanasiga elektron qurilmalar kiritilgan kunni ham ko'rishimiz mumkin. Masalan, qachonlardir MP3 pleer o'rniga odam tanasiga jarrohlik yo'li bilan o'rnatib qo'yishi mumkin, bu ovoz to'g'ridan-to'g'ri quloqlariga tushadi.
