Name two types of transistors mentioned in the text.

What are the subtypes of the Bipolar Junction Transistor (BJT)?

The transistor was invented in 1947 by scientists at Apple Inc.

Transistors are larger and less efficient than vacuum tubes.

Semiconductors like silicon conduct electricity better than conductors.

Transistors can only be made of insulators like glass or rubber.

Doping semiconductors with materials like phosphorus can decrease their conductivity.

'Field Effect Transistor (FET)' is a type of transistor mentioned in the text.

Inventions like the wheel, printing press, steam engine, and electricity have transformed human life, but the transistor stands out as the most significant technological revolution of the 20th century.
The transistor was invented in 1947 by scientists at Bell Labs, John Bardeen, Walter H. Brattain, and William B. Shockley, changing the world dramatically.
The transistor serves as a switch in circuits, automatically opening and closing circuits at high speeds and can be remarkably small.
Transistors replaced bulky vacuum tubes in devices like radios, leading to the development of portable and efficient electronic devices.
Transistors are made of semiconductors like silicon, which can conduct electricity better than insulators but not as well as conductors.
By doping semiconductors with other materials like phosphorus or aluminum, their conductivity can be enhanced, creating "N-type" or "P-type" semiconductors.
Transistors come in different types such as Bipolar Junction Transistor (BJT) and Field Effect Transistor (FET), with BJT having subtypes like PNP and NPN.
Transistors act as automatic switches and amplifiers, playing a crucial role in electronics, from simple circuits to complex integrated circuits (chips) present in nearly all modern technology.
The miniaturization of transistors has followed Moore's Law, allowing for the exponential increase in transistor density on microprocessors, although physical limits may soon be reached due to heat generation and quantum mechanics constraints.
