    Study Notes

    Peripheral Storage Devices

    • Peripheral storage devices store and back up information
    • Examples include diskettes, flash drives, and memory cards

    Printers

    • Printers are peripheral output devices attached to the CPU
    • They print processed information

    Printer Types

    • Dot Matrix Printers (DMP):
      • Popular and inexpensive
      • Create characters by dots in patterns (e.g., 7 rows by 9 columns)
      • Fast, versatile, economical, and multi-purpose
      • Example: EPSON FX 1050
    • Daisywheel Printers (DP):
      • Use a thimble-shaped printing element (daisywheel)
      • Produce letter-quality text
    • Laser Jet Printers (LP):
      • High-resolution printers
      • Based on photocopy technology
      • Produce high-quality text and graphics
      • Example print resolutions: 300 or 600 dots per inch
      • Newer types include inkjet and heat-sensitive printers

    Tape Units

    • Tape units are peripheral storage devices
    • Provide cheap and reliable backup for vital information
    • Useful for backing up large volumes of data, like diskettes

    Keyboards

    • Keyboards are input devices used to send data into the system
    • Two main types: standard and enhanced

    Software Introduction

    • Software are intangible instructions that tell the computer what to do
    • Two main categories: application and system software

    System Software

    • Interacts at a basic level with the computer
    • Manages files, input/output devices and removes viruses
    • Examples: operating systems, utilities, language translators

    Application Software

    • Enables users to perform specific tasks
    • Does not interact directly with the computer
    • Examples: word processors, spreadsheets, and graphics software.

    Comparison of Application and System Software

    • System software: General term for digitally stored data like programs, and information (e.g., Microsoft Windows, Linux, Unix).
    • Application software: Software that helps users accomplish tasks (e.g., web browsers, word processors).
    • System software operates in the background. Application software is used for tasks
    • System software is independent and application software needs system software to run

    Operating Systems

    • Operating systems are the most important programs on a computer
    • They control all activities on the computer
    • Examples: Microsoft Windows, Mac OS, UNIX, Linux, Windows Mobile OS, iOS, Android OS

    Utilities

    • Utility programs optimize computer performance, protect data, and facilitate communication.
    • Examples include antivirus software, backup software, and compression utilities

    Language Translators

    • Translate high-level language programs into machine language
    • Examples include compilers and interpreters

    Word Processors

    • Produce documents like letters, memos, reports, and manuscripts
    • Allow editing, formatting, and spell-checking

    Spreadsheets

    • Organize data in rows and columns with formulas
    • Used for tasks like budgeting, tracking finances, calculating loan payments, and grading
    • Examples include Microsoft Excel and Open Office Calc.

    Database Management Systems

    • Databases store data on one or more computers
    • Databases management systems (DBMS) are programs to store, modify, find, and report data
    • Examples of DBMS: Microsoft Access, Oracle, and MySQL

    Presentation Software

    • Combines text, graphics, photos, sounds and animation into slides
    • Commonly used on monitors or projectors. (e.g., Microsoft PowerPoint, Open Office Impress, Google Presentation)

    Graphics Software

    • Create, edit, and manipulate graphics (images, drawings, icons, or photographs)
    • Different types: paint software (e.g., Microsoft Paint and Corel Painter) and drawing software (e.g., Adobe Illustrator and Corel DESIGNER)

    Photo Editing Software

    • Enhance poor photo quality by adjusting brightness, contrast, etc.
    • Example: Adobe Photoshop

    Applications of Computers

    • Computers are widely used for education, entertainment, sports, advertising, medicine, science/engineering, and government

    Practice Questions

    • Detailed questions about computer systems and components (e.g., first-generation circuitry, Babbage's inventions, hardware functions, input devices)
