Transistor transistor logic is one type of many different types of bipolar transistor based digital logic circuitry. It is very efficiently implemented in integrated circuit chips, needs only one power supply voltage, and operates at reasonably high speeds. Transistor transistor logic was first developed in the middle 1960s as a modification of the diode transistor logic, then in use in some digital logic integrated circuit chips but dating back to the earliest discrete bipolar transistor logic developed in the late 1950s and derived from vacuum tube point contact diode logic used in many early first generation computers. Transistor transistor logic integrated circuits dominated the computer and electronic digital controller market from the late 1960s until the middle 1980s, when metal oxide semiconductor field effect transistor based microprocessors and microcontrollers began to replace it. By the early 1990s transistor transistor logic and other bipolar transistor based digital logic integrated circuits had been replaced with equivalent complementary metal oxide semiconductor field effect transistor integrated circuits that were both faster and consumed less power (thus running much cooler) or with programmable logic devices of various types. In general transistor transistor logic is now considered obsolete.
A silicon transistor is a transistor made of silicon.
Similar to a 2N3906 PNP transistor
A Darlington amplifier consists of two bipolar junction transistors (BJTs) connected in a configuration that allows the current amplified by the first transistor to drive the second transistor. This arrangement results in a very high current gain, as the output current of the first transistor becomes the input current for the second. The input signal is applied to the base of the first transistor, which greatly amplifies it before passing it to the base of the second transistor for further amplification. The overall effect is a significant increase in both current and voltage gain, making it useful in various applications where high gain is required.

The word "transistor" is a blend of "transfer" and "resistor," reflecting its function of transferring electrical signals across a resistor. It was coined by John R. Pierce, an engineer at Bell Laboratories, where the first transistor was developed in 1947.
I know it was BELL laboratory in the fifty I believe
Emitter biasing is when you add a resistor between the emitter of a transistor and the 0v rail so that any voltage developed across the emitter will subtract from the voltage on the base and effectively turn the transistor OFF. We are talking about an NPN transistor and the transistor is an "ordinary transistor" or BJT (bi-polar Junction Transistor). For more information on transistor biasing see: Talking Electronics website.

1947 at Bell Labs. It was a germanium point contact transistor.
The transistor was invented by John Bardeen, Walter Brattain, and William Shockley at Bell Labs in 1947. They developed the first point-contact transistor, which was a crucial advancement in semiconductor technology. This invention laid the foundation for modern electronics, enabling the development of various devices, including computers and smartphones. Their work earned them the Nobel Prize in Physics in 1956.
1947
The transistor was created by researchers at the university of Geneva. "The first patent for a field-effect transistor principle was filed in Canada... 1925. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor."
