Biz fanning jozibali va qiyin dunyosida yashayapmiz. Bu dunyo tobora ko'proq va ayniqsa 20-asrda bizning hayotimizning ko'p qismiga ta'sir ko'rsatadigan dunyo. Bu bizning sayohatimiz, yashayotgan uylarimiz va kiyinishimiz, qanday kasal bo'lib qolganimiz va tibbiyot bizni qanday qilib yaxshilashi mumkinligi bilan bog'liq bo'lib, bizga ajoyib muloqot va kashfiyot vositalarini taqdim etdi. Texnologiya bu bilimlarni inson hayotining amaliy maqsadlariga yoki inson atrofini o'zgartirish va boshqarish uchun qo'llashdir. Bu fan va kompyuterlar haqidagi zamonaviy bilimlarga asoslangan yangi mashinalar, uskunalar va ishlarni bajarish usullari.
Texnologiyalar hayotni engillashtirish yoki yoqimli qilish va samaraliroq ishlash uchun materiallar, asboblar, texnika va quvvat manbalaridan foydalanishni o'z ichiga oladi. Ilm-fan voqealar qanday va nima uchun sodir bo'lishi bilan bog'liq bo'lsa, texnologiya voqealarni amalga oshirishga qaratilgan.
Odamlar asboblardan foydalanishni boshlashi bilan texnologiya insoniyat harakatiga ta'sir qila boshladi va sanoat inqilobi va mashinalar hayvon va odam mehnatiga almashtirilishi bilan tezlashdi. Tezlashtirilgan texnologik rivojlanish, shuningdek, havo va suvning ifloslanishi va atrof-muhitning boshqa nomaqbul ta'siriga bog'liq xarajatlarga olib keldi.

Technology includes the use of materials, tools, techniques, and sources of power to make life easier or more pleasant and work more productive. Whereas science is concerned with how and why things happen, technology focuses on making things happen.
Technology began to influence human endeavour as soon as people began using tools, and accelerated with the Industrial Revolution and the substitution of machines for animal and human labour. Accelerated technological development has also had costs, in terms of air and water pollution and other undesirable environmental effects.
Increasing computational power – and increasing product quality – matters indeed more than a mere doubling of transistors. But if the technologically-advanced products are prohibitively expensive then they can only have a limited impact on the whole society. For this reason, it is interesting to look at both the product quality and the price. The author and inventor Ray Kurzweil analyzed the change of price and quality for computing machines since 1900. He not only analyzed the improvements of integrated circuits but also looked at the predecessors – earlier transistors, vacuum tubes, relays and electromechanical computers. What he found is that Moore did not only make a valid prediction of the future, but his description is also valid for the past! The exponential growth rate that Moore picked up in the 1960s was driving technological progress since the beginning of the century.
This graph shows the computer power that consumers could purchase for a price of $1000. It is especially insightful if one wants to understand how technological progress mattered as a driver of social change.
