1st Generation (1940s-1950s): Vacuum Tubes were used in early computers like ENIAC.
2nd Generation (1950s-1960s): Transistors replaced vacuum tubes, making computers smaller and more efficient.
3rd Generation (1960s-1970s): Integrated Circuits (ICs) improved speed and reduced size.
4th Generation (1970s-Present): Microprocessors led to personal computers (PCs).
5th Generation (Present & Future): AI & Quantum Computing define the future of computing.
