Study Notes
Early Computing Devices
- Blaize Pascal invented the Pascaline in 1642, a mechanical calculator for performing addition and subtraction directly.
- The Pascaline could also perform multiplication and division through repeated operations.
- Herman Hollerith designed the first tabulating machine for data summarization using punched cards, marking a step towards programmable machines.
Introduction of Stored Program Concept
- John Von Neumann introduced the stored program computer concept, enabling data and programs to be stored in memory.
- The EDVAC (Electronic Discrete Variable Automatic Computer) and ENIAC (Electronic Numerical Integrator and Computer) were developed based on this architecture.
- ENIAC was the first binary programmable computer utilizing Von Neumann architecture.
Advancements in Integrated Circuits
- Integrated Circuits (ICs) emerged, allowing entire electronic circuits to reside on a small silicon chip.
- The development of Very Large Scale Integration (VLSI) in the 1980s integrated approximately 3 million components on single chips.
- Further advancements led to Super Large Scale Integration (SLSI), accommodating around 10^6 components on one IC.
Moore's Law
- Moore's Law, articulated by Intel’s co-founder Gordon Moore in 1965, predicted that the number of transistors on a microchip would double every two years while costs would halve.
- This exponential growth is exemplified by the increase in the number of transistors in microprocessor generations, from 4004 to Core i7 processes.
Personal Computing Revolution
- IBM introduced its first personal computer (PC) for home users in 1981.
- Apple launched the Macintosh in 1984, further expanding the personal computer market.
Von Neumann Architecture Components
- The Von Neumann architecture includes a Central Processing Unit (CPU) for arithmetic and logical processing, memory for data and program storage, input/output devices, and communication channels.
- The architecture enables efficient data processing and is foundational for modern computer systems.
Microprocessor Development
- During the 1970s, Large Scale Integration (LSI) technology achieved integration of an entire CPU onto a single microprocessor chip.
- Moore's Law maintained relevance as microchips evolved, facilitating greater transistor density and processing capabilities.
