Early Computing Era

The first electronic computer ENIAC (1945) filled a large room and used vacuum tubes for calculations. Transistor invention in 1947 enabled smaller, more reliable computers. By 1960, integrated circuits marked the shift to second-generation computing, reducing size and power requirements while increasing processing speed.

Personal Computer Revolution

The 1970s-80s brought microprocessors and personal computers like the Apple II and IBM PC. Microsoft and Apple developed user-friendly operating systems, making computers accessible to homes and businesses. Memory capacity and processing power doubled approximately every 18 months, following Moore's Law.

Modern Computing

Current technology features quantum computing development, artificial intelligence integration, and cloud computing infrastructure. Mobile devices provide computing power exceeding early mainframes. Advances in chip design and materials push toward nanoscale computing, while quantum computers tackle previously impossible calculations. Shutdown123
