Study Notes
Computer Evolution and Architecture
- Computers evolved from simple calculation devices to the sophisticated systems we use today, driven by miniaturization and integration.
- Early stages involved small-scale, medium-scale, large-scale, and now very-large-scale integration.
- Blaise Pascal created a 17th-century calculator for addition and subtraction, needing repeated steps for multiplication and division.
- Charles Babbage designed a complex mechanical calculator (analytical engine) with 8,000 parts, weighing 5 tons and measuring 11 feet.
- ENIAC (Electronic Numerical Integrator and Calculator) was the first electronic computer, notable for its significant heat generation.
- Mainframe computers followed, contributing to modern processor development.
- The third computer generation saw the use of semiconductors, including Small-Scale Integration (SSI) and Medium-Scale Integration (MSI).
- Computer architecture advancements led to systems like the ubiquitous Internet of Things (IoT), characterized by sensors with processing capabilities.
- Personal Computers (PCs) have improved, but power consumption remains a significant concern.
- Moore's Law, proposed by Gordon Moore of Intel in 1965, predicts a doubling of transistors on a microchip roughly every 18 months.
- Key computer components include:
- CPU (Central Processing Unit): Executes instructions.
- ALU (Arithmetic Logic Unit): Performs arithmetic and logical operations.
- Memory: Stores data and instructions.
- Control Unit: Manages instruction and data flow through the CPU.
- Instructions are commands that direct the computer's actions.
- Stored in memory, instructions are fetched by the control unit and processed by the ALU.
- Memory types include:
- Primary Memory (RAM): Fast, volatile, used for temporary program execution.
- Secondary Memory (Hard Drives or SSDs): Slower, persistent storage for data and programs.
- Input devices receive user data, while output devices display results.
