How did early computers work?

Early computers, also known as first-generation computers, worked using vacuum tubes and punched cards. These computers were large, bulky machines that required a considerable amount of power and cooling. The vacuum tubes acted as electronic switches to control the flow of electricity, transmitting binary code in the form of on and off states. The punched cards were used to input instructions and data into the computer. The computer then processed this information using complex circuits and performed calculations or executed tasks accordingly. Although these early computers were slow compared to modern ones, they were revolutionary in their time and laid the foundation for the development of advanced computing technologies.
