2. Second Generation (1950s-1960s):
Technology: Transistors.
Characteristics: Smaller size, less heat generation, improved speed and reliability.
Example Computers: IBM 1401, IBM 7090.
3. Third Generation (1960s-1970s):
Technology: Integrated Circuits (ICs).
Characteristics: Further reduction in size, increased speed, and improved efficiency.
Example Computers: IBM System/360, DEC PDP-11.
4. Fourth Generation (1970s-1980s):
Technology: Microprocessors.
Characteristics: Very small size, higher speed, lower cost, and the advent of personal computers.
Example Computers: IBM PC, Apple Macintosh.
5. Fifth Generation (1980s-Present):
Technology: VLSI (Very Large Scale Integration), parallel processing.
Characteristics: Increased processing power, AI (Artificial Intelligence) development.
Example Computers: IBM Watson, modern supercomputers.
6. Sixth Generation (Future):
Technology: Advanced AI, quantum computing (speculative).
Expected Characteristics: Further advancements in AI, quantum computing capabilities.
Under Development: Quantum computers, AI-driven systems.
Each generation represents a significant leap forward in terms of computing capabilities and has contributed to the evolution of modern computers.
