Are the electronic devices used in ENIAC computers transistors?

The world's first electronic computer.

Actually, it's ABC (Atanasoff-Berry Computer).

The electronic computer "Eniac" was born on February 14, 1946 at the University of Pennsylvania in the United States.

It was officially announced the next day.

Measuring meters long, 6 meters wide and meters high, the ENIAC covers an area of about 170 square meters, has 30 operating stations, weighs 30 tons, consumes 150 kilowatts of electricity, and costs $480,000. It contains 17,468 vacuum tubes and 7,200 crystal diodes.

1,500 relays, 70,000 resistors.

10,000 capacitors, 1,500 relays, more than 6,000 switches, 5,000 additions or 400 multiplications per second, 1,000 times more than relay computers and 200,000 times more manual calculations.

The post mentions that the main components of ENIAC are vacuum tubes and transistor diodes. For the introduction of vacuum tubes, please refer to:

Since you asked about transistors, you should know at least what they look like, and you can make a visual comparison.

ENIAC, the full name of electronic numerical integrator and computer, that is, electronic numerical integration computer. ENIAC was the second electronic computer and the first general-purpose computer after the ABC (Atanasov-Berry Computer).

It was a fully electronic Turing computer capable of being reprogrammed to solve a variety of computational problems. It was proclaimed in the United States on February 14, 1946. The development task consisted of scientist Johann von Neumann and engineers Eckert, Mockley, and Goldstein from the "Moore Group".

Chief engineer Eckert was only 25 years old at the time.

Vacuum tubes, if you have that kind of oversized radio at home from many years ago, you can find out what tubes look like in them, because tubes are too big, fragile, and too power-intensive, so they will be replaced by transistor integrated circuits

It's said it's an electronic computer, it must be an electron tube. None of the answers are correct.

(For example, if I want to make a computer, how do I think about how it works and how it works?) By what treatment?? It can be understood as an infinite number of electric lights some lights on and some lights off the switch i o

We all know that the first computers were made up of diode elements.

It consists of 17,468 tubes, 60,000 resistors, 10,000 capacitors and 6,000 switches, weighs 30 tons, covers an area of 160 square meters, consumes 174 kilowatts of electricity, and costs $450,000. This computer can only run 5,000 addition operations per second, which is only equivalent to an electronic digital integration computer (ENIAC"Eniake"）。
