Computing Fundamentals

This section provides an overview of operating systems (OS), essential system software that facilitates communication between users, hardware, and application software. It explores various OS types, including DOS (text-based), Windows, Mac OS, Linux, and mobile systems like Android and iOS. Key functionalities such as resource management, user interfaces (Command Line Interface vs. Graphical User Interface), and the boot-up process are explained. Learn about the differences between proprietary and open-source systems, and discover how user interactions shape their computing experience. ###

  1. Computing Fundamentals Unit 6- Operating Systems

  2. The OS • System software • Allows user & hardware to communicate with application software & reverse • Manages resources • Every PC needs one

  3. Operating Systems • DOS • Old • Text based, single task only • Command Prompt • Windows • 3.0, 3.1, 95, 98, 2000, Me, XP, Vista, 7 • Mac OS • Network OS (NOS) • Novell, Windows Server • Allows shared access, security

  4. DOS • Found in Command Prompt

  5. Windows- Through the Years

  6. Mac OS

  7. Linux • Similar to Windows/Mac • Free • Open to coding/ changes by the user

  8. UNIX • More for programming

  9. Handheld OS • Blackberry, Palm, Android, Windows Mobile

  10. Boot Up Process • POST (verifies hardware) • ROM passes boot instructions to RAM • OS located on HD, loaded into RAM • C: Drive

  11. User Interfaces • How you interact with OS • Command Line Interface (CLI) • DOS • Graphical User Interface (GUI) • Icons to click

  12. Review • Which user interface must you type out commands instead of clicking icons? • CLI • Where is the OS stored? • Hard drive • Where does the OS get loaded onto when the computer boots? • RAM • Which OS is free and allows users/programmers to change coding to improve it? • Linux

  13. Review • Name a mobile OS. • iPhone, Android, Windows Mobile, others • Which type of user interface is Windows? • GUI • What happens first when you turn on your computer? • POST, check hardware • What part of the computer contains boot instructions? • ROM
