Which generation of electronic computers uses electron tubes as the main logic component

The main logic component used in the first generation of electronic computers was vacuum tubes.

Related knowledge introduction:

The main logic component used in the second generation of electronic computers is the transistor.

The main logic component used in the third generation of electronic computers is integrated circuits.

ENIAC, the world's first electronic computer, covers an area of ​​170 square meters, weighs 30 tons, consumes about 150 kilowatts per hour, and can perform 5,000 operations per second.

Since the birth of the first generation of computers, computer technology and industry have been in a stage of rapid development. Computer science has become a discipline with rapid development, strong penetration, and far-reaching influence. The computer industry has developed into an industry of strategic significance worldwide. The degree of development of computer science and computer industry has become an important indicator of a country's comprehensive national strength.

Electronic tube is one of the earliest electrical signal amplifier devices. The cathode electron emission part, control grid, acceleration grid, and anode (screen electrode) leads enclosed in a glass container (usually a glass tube) are welded to the tube base. The electric field is used to inject electronic modulation signals into the control grid in the vacuum, and different parameter signal data after signal amplification or feedback oscillation are obtained at the anode.
