Study Notes
Early Civilizations and Contributions to Computing
-
Babylonians (2000 BC - 500 BC)
- Introduced a numerical system based on two symbols for 1 and 10.
- Created tables for arithmetic, square roots, and cubes.
- Utilized counting boards and early abacus versions for calculations.
-
Egyptians
- Developed a base 10 numerical system with hierarchical symbols (1, 10, 100, 1,000, etc.).
- Applied mathematics to solve practical problems in time measurement, taxation, and land calculations.
- The Rhind Papyrus featured arithmetic and geometric problems, aiding construction projects.
-
Greeks (500 - 600 BC)
- Pythagoras: Formulated the Pythagorean Theorem.
- Thales: Known for his theorem regarding triangles in Euclidean geometry.
-
Romans
- Employed Roman numerals (I, V, X, etc.) for various applications.
- Utilized abacuses for calculations, contributing to numerical practices.
- Roman numerals remain in use today in clocks, monuments, and sports events.
-
Islamic Influence
- Made significant advances in algebra, incorporating rational and irrational numbers.
- Unified arithmetic, geometry, and algebra to study various mathematical curves.
Notable Figures in Computing
-
Wilhelm Gottfried Leibniz
- Developed the binary number system foundational for modern computing.
- Invented the Step Reckoner, capable of performing all basic arithmetic operations.
-
Charles Babbage
- Designed the Difference Engine for calculating polynomial and trigonometric functions.
- Recognized as the "grandfather of computing," his machine was later completed by Swedish engineers in 1853.
-
George Boole
- Laid the groundwork for Boolean algebra, essential for computer science.
- Introduced binary logic (1 and 0) and logical operators.
-
Grace Brewster Murray Hopper
- Played a key role in developing COBOL (Common Business-Oriented Language).
- Advanced the standardization of programming languages for business applications.
-
Katherine Johnson
- Calculated trajectories for NASA, crucial to safe space travel.
- Her work enabled the successful return of astronauts from the moon.
-
Gladys Mae West
- Developed a model of the Earth’s surface underpinning GPS technology.
- Significantly enhanced satellite geodesy and radar precision.
Modern Computing Technologies
-
Cloud Computing
- Provides internet-based computing services, enabling data and application access from any internet-connected device.
- Examples include Google Drive (cloud storage) and Netflix (streaming service).
- Advantages highlight on-demand services and reduced physical storage dependency.
-
Virtualization
- Enables the creation of virtual versions of physical hardware resources.
- Includes server virtualization (multiple servers on one machine) and desktop virtualization (multiple OS on one computer).
- Often used in cloud computing for resource management.
-
Internet of Things (IoT)
- Represents a network of connected physical objects that gather and share data online.
- Key technologies include RFID and sensor technology for environmental monitoring.
- Applications span GPS systems and smart home devices.
-
Big Data
- Comprises extensive datasets characterized by high volume, variety, and velocity.
- Banking uses include monitoring markets and detecting fraud.
- In healthcare, assists in evidence-based medicine through patient record analysis.
-
Artificial Intelligence (AI)
- Technology allowing machines to learn from experience and perform intellectual tasks.
- Examples include facial recognition for security and chatbots for customer service.
- AI integrates with cloud computing and big data for enhanced capabilities.
-
Fog Computing
- An extension of cloud computing, processing data closer to the network's edge for real-time insights.
- Useful in smart cities and industrial settings for local analytics.
-
Edge Computing
- A distributed computing approach enabling data processing at the source rather than a centralized cloud.
- Facilitates faster processing and reduced latency in data handling.
