    Study Notes

    Computer System Overview

    • An electronic data processing machine capable of mathematical and logical operations, processing large volumes of data rapidly.
    • A system consists of organized, interdependent components that interact to achieve predetermined goals.

    Characteristics of a Computer

    • Speed: Initially invented as a high-speed calculator; can add two 18-digit numbers in 300 to 400 nanoseconds.
    • Accuracy: Consistently high accuracy, although errors can occur due to machinery; advanced error detection minimizes false results.
    • Storage: Can store large amounts of data permanently, including text, graphics, audio, and video files. Storage capacity is increasing rapidly.

    Types of Systems

    • Closed System: No input or output; isolated from its environment.
    • Open System: Has inputs and outputs, interacting with the environment.

    Data Processing Cycle

    • Consists of origination, input preparation, processing, output preparation, and storage.
    • Represents the flow of data from recording to usable information.

    Evolution of Computers

    • Tally Stick: Used for recording quantities and messages (40,000 - 10,000 years).
    • Abacus: Ancient calculating tool (2700-2300 BC) from various cultures.
    • Stepped Reckoner (1672): Mechanical calculator by Leibniz, capable of basic arithmetic.
    • Jacquard Loom (1804): Introduced punched cards for automatic weaving.
    • Napier's Bones (1617): A device for simplifying multiplication and division.
    • Slide Rule (1622): Mechanical analog computer for complex calculations.
    • Arithmometer (1850-1851): First commercially successful mechanical calculator by Charles de Colmar.
    • UNIVAC 1: The first commercial computer in the U.S., designed by Eckert and Mauchly.
    • EDVAC (1952): One of the earliest electronic computers, the first stored program computer developed by von Neumann.

    Key Figures in Computer Science

    • Charles Babbage: Often referred to as the "Father of the Computer," known for the Analytical Engine.
    • Augusta Ada Byron: Recognized as a pioneer in computer science for her work with Babbage.
    • John von Neumann: Essential figure in computing, known for the architecture that underlies most computers today.

    Generations of Computers by Size

    • First Generation (mid-1940s to late 1950s): Vacuum tubes and punch cards for input.
    • Supercomputers: High performance for research.
    • Mainframe Computers: Used by large enterprises for data management.

    Computer Capabilities

    • Ability to perform logic operations and complex calculations.
    • Capable of accurate data storage and retrieval.
    • Performs automatic operations and error detection.

    Limitations of Computers

    • Dependence on programmed instructions; they do only what they are programmed to do.
