Study Notes
First Generation (1945-Second World War)
- Computers employed vacuum tubes, which are sealed glass tubes containing a vacuum, facilitating the flow of electricity.
- The flow of electrons between sections of the tube enables computation.
- Vacuum tubes were replaced by transistors in the second generation.
- Notable examples of first-generation computers include UNIVAC (Universal Automatic Computer) and ENIAC (Electronic Numerical Integrator and Computer).
Second Generation (1956-1968)
- Transistors replaced vacuum tubes in the second generation, resulting in smaller, more cost-effective, and energy-efficient computers.
- Transistors were made of semiconductors; silicon being a prime example.
- Semiconductors facilitate the controlled flow of electric current.
- Transistors regulated the current flow in second-generation computers.
