None, the transistor did not yet exist. It was built with vacuum tubes and had roughly 18,000 of them.

When a project was done to recreate ENIAC on a chip, it took about 180,000 transistors. But you have to realize that the vast majority of these transistors are not active processing transistors, but are just switches to simulate the plugging in of the program cables into different connectors on the various panels. Only one wafer of ENIAC on a chip was ever made, it needed a PC to translate a cabling diagram to internal switch settings and load the settings into the chip. The PC was a more powerful computer than ENIAC. Most of the ENIAC on a chip devices never saw use, they went to museums or computer history collectors.

How many transistors did the ENIAC have?

Eniac didn't have any transistors. It was built with 17,468 vacuum tubes, 7,200 crystal diodes, and a whole host of other components. But no transistors. The first transistor was created in November, 1947, almost two years after Eniac was completed.

What is different of eniac and uniac?

ENIAC (Electronic Numerical Integrator and Computer) was one of the earliest general-purpose electronic computers, developed in the 1940s, and it used vacuum tubes for computation. UNIAC (Universal Automatic Computer), often referred to as UNIVAC, was the first commercially available computer, introduced in the early 1950s, and it utilized transistors instead of vacuum tubes, making it more reliable and efficient. Essentially, ENIAC was a pioneering machine in the realm of computing, while UNIVAC marked the transition to practical commercial computing.

Was the eniac computer the first computer to be created?

No, the following digital computers preceded ENIAC: Harvard Mark I, ABC, Zuse Z1 & Z2 & Z3, Colossus Mark 1 & Mark 2. Also many analog computers preceded these.However ENIAC was the first general purpose programmable electronic digital computer.
