What were the characteristics of the first generation of computers?

The characteristics of the first generation of computers are: 1. Use electron tubes as basic components; 2. Use mercury delay lines as storage devices, and later gradually transition to magnetic core memories; 3. Input and output devices are mainly Punch cards are very inconvenient for users to use; 4. The system software is still very primitive, and users must master programming methods similar to binary machine language.
