What were the electronic components of the world's first computer?

The electronic component of the world's first computer was a vacuum tube.

The world's first general-purpose computer "ENIAC" was born on February 14, 1946 at the University of Pennsylvania. The inventors are Americans John W. Mauchly and J. Presper Eckert.

ENIAC uses electron tubes as components, so it is also called a tube computer and is the first generation of computers. Because the electron tubes used in electron tube computers are large in size, consume a lot of power, and are prone to heat, they cannot work for too long.
