What technology did transistors replace?

vacuum tubes
Bell Labs publicly announced the first transistor at a press conference in New York on June 30, 1948. The transistor went on to replace bulky vacuum tubes and mechanical relays. The invention revolutionized the world of electronics and became the basic building block upon which all modern computer technology rests.

What old device did the invention of transistors replace?

vacuum-tube triode
The transistor replaced the vacuum-tube triode, also called a (thermionic) valve, which was much larger in size and used significantly more power to operate. The first transistor was successfully demonstrated on December 23, 1947 at Bell Laboratories in Murray Hill, New Jersey.

How transistor changed the world?

Transistors transformed the world of electronics and had a huge impact on computer design. By replacing bulky and unreliable vacuum tubes with transistors, computers could now perform the same functions, using less power and space. Before transistors, digital circuits were composed of vacuum tubes.

What will replace transistors in future?

IBM aims to replace silicon transistors with carbon nanotubes to keep up with Moore’s Law. A carbon nanotube that would replace a silicon transistor. IBM has developed a way that could help the semiconductor industry continue to make ever more dense chips that are both faster and more power efficient.

What are the evolution advances the transistor went through?

Germanium transistors broke down at high temperatures, so they were eventually replaced by silicon transistors. Gordon Teal built the first silicon transistor, which worked just like a germanium junction transistor. 1960s: The next big jump in transistor evolution came with the field-effect transistor.

What replaced transistor based computers in the 1960s?

Over the course of the 1960s and 1970s, transistors became smaller and smaller. Many of the large mainframe computers that had been required to meet the computer needs of a large company were replaced by minicomputers (“mini-” having become a pop culture prefix of the 1960s—e.g., “miniskirt”).
