    Study Notes

    Introduction to Computers

    • A computer is a machine programmed to perform arithmetic and logical operations.
    • Computer systems can include hardware, operating systems, software, and peripherals.
    • Networks or clusters of computers can function together.
    • Early computers used vacuum tubes, moving to transistors and integrated circuits.
    • Computers are used in a wide range of applications, from simple devices to complex systems.
    • Early forms of calculation include the abacus and mechanical devices.
    • The digital electronic calculators began during the 20th century.

    Computer Components

    • Computer hardware includes physical components like monitors, keyboards, mice, hard drives, etc.
    • Software comprises sets of instructions for the computer to execute tasks.
    • Different types of computers include supercomputers, mainframes, minicomputers, workstations, personal computers, laptops, netbooks, mobile devices, and tablets.
    • The CPU (Central Processing Unit) is the "brain" of a computer.
    • The ALU (Arithmetic Logic Unit) performs calculations and comparisons.
    • The CU (Control Unit) manages and coordinates computer functions.
    • RAM (Random Access Memory) is temporary storage for active data and instructions.
    • ROM (Read-Only Memory) is permanent storage for essential instructions.

    Input Devices

    • These devices provide data to the computer.
    • Examples include keyboards, mice, touchscreens, scanners, microphones, cameras, and joysticks.
    • Input devices translate data into a format recognizable by the computer.

    Output Devices

    • These devices display or communicate the results of processing.
    • Examples include monitors, printers, speakers, projectors, and plotters.
    • They convert computer data into a form understandable by humans.

    Types of Software

    • System software manages the computer's hardware and operations.
    • Application software performs specific tasks.
    • Examples of system software include operating systems (Windows, Linux, macOS).
    • Examples of application software include web browsers, word processors, spreadsheets, and games.

    Data, Information, and Knowledge

    • Data are raw facts and figures.
    • Information is processed data that provides context and meaning.
    • Knowledge is understanding gained from information and experience.

    Computer Characteristics

    • Speed: Computers execute tasks at high speeds.
    • Accuracy: High levels of precision in calculations.
    • Diligence: Continuous operation without fatigue.
    • Storage Capability: Ability to store large amounts of information.
    • Versatility: Ability to handle various tasks.

    Computer Viruses
