Presentation Transcript

  1. CSI 400/500 Operating SystemsSpring 2009 Lecture #1 – Operating System Fundamentals Wednesday January 21, 2008

  2. OS Body

  3. OS Forms

  4. OS Shell • Command based • Simple Interface • Text output • Example: Unix sh

  5. GUI • Graphical User Interface • Event driven • Display items cause events to occur • Example: MS Windows

  6. DBMS • Database Management Systems • Translates data commands into system functions • Can be text or graphical • Examples: SQL, PowerBuilder

  7. Driver Library • Selection of different functional kernels • Correct kernel chosen by system • Often given parameters to consider • Example: Linux

  8. OS Strategies

  9. Batch Systems • Sequence of commands • Self-contained • No interaction • Still used today • Example: IBM JCL

  10. Timeshare Systems • Multi-user, “single” processor • Limited access • Large jobs run in background • Examples: IBM TSO, Plato

  11. Workstations • Modern personal computer • Independent or networked • Separate processor

  12. Networks • Join workstations and data resources • Access control • New concerns • Example: WWW

  13. Embedded Systems • Control system • Self-contained • Self-correcting • Real time system • Examples: satellites, power stations, autos

  14. PDAs • Personal digital assistant • Small handheld workstation • Focused on communication
