Evolution of Computer Systems

First generation computers used vacuum tubes, had limited storage capacity, and used punched cards for I/O operations.

Second generation computers used transistors and diodes, had increased speed of computing measured in microseconds, reduced heat production, improved reliability, and increased storage capacity. They also used magnetic tapes instead of punched cards for I/O operations.

Third generation computers used integrated circuits, had faster computing speed measured in nanoseconds, occupied less space, and had devices like visual display units for I/O operations.
