The invention that helped reduce the size of electronic devices in 1947 was the transistor. Developed by John Bardeen, Walter Brattain, and William Shockley at Bell Labs, the transistor replaced bulky vacuum tubes, allowing for smaller, more efficient, and more reliable electronic circuits. This breakthrough paved the way for the miniaturization of technology, ultimately leading to the development of modern electronics such as computers, smartphones, and various digital devices.
the invention of the transistor
After World War II, several significant inventions transformed daily life and technology. Notable innovations include the invention of the transistor in 1947, which revolutionized electronics and paved the way for modern computing. The development of the laser in 1960 and the introduction of the first commercial jet airliner, the Boeing 707, in the late 1950s also marked major advancements in communication and transportation. Additionally, the invention of the microprocessor in the early 1970s laid the foundation for the digital age.
The transistor
They developed the first working transistor at Bell Laboratories in 1947, which revolutionized the field of electronics and paved the way for modern technology such as computers and smartphones. This invention marked the beginning of solid-state electronics and led to the eventual replacement of vacuum tubes with much smaller and more efficient transistors.
The transistor was successfully demonstrated on December 23, 1947 at Bell Laboratories in Murray Hill, New Jersey. Bell Labs is the research arm of American Telephone and Telegraph (AT&T).
It was the Transistor!
Most likely the Silicon Chip.
before the invention of transistor,thyristor was used instead of transistor but thyristor produces more heat in the circuit and size is more when compared to transistor
Pakistan Revolution (1936 - 1947).
Vaino J. Holopainen and Roy E. Handy, Jr. are credited with invention of the backhoe loader in July 1947. Holopainen filed a patent for this invention in July of 1948.
