Operating Systems Laurie Ganz Klye Leahy Tommy Mendoza Heather Shriner Katie Wagner Operating System “ an interface between your computer and the outside world. ” organize and control hardware and software so that the device it lives in behaves in a flexible but predictable way. Operating System Functions • Translation • Monitoring the computers overall performance • Provides functions The Evolution of Operating Systems • No Operating Systems • Monitors • Simple Batch Systems • Multiprogrammed Batch Systems • Time Sharing Systems When Operating Systems didn’t Exist • technological capabilities • Individual Programs • One person used the computer at a time • “Job Scheduling” • Libraries 1st procedure Monitors • RAM • device drivers •jumping back to the monitor. Simple Batch Systems • Punched Cards • Input process • Operating system process • Output Process Job Control Language •JCL was used? • Identified as JCL or data. • What program needs to be run or what data file will be used. Multi -Programmed Batch Systems • Several programs • Switch from one user environment to another. • Relied on hardware Time Sharing • Multiprogramming • Time Shared • Multiple users • A new control language UNIX…………1960’s. •Widely Accepted and available specifications •Assurance that products meet agreed specifications •Three parts to its operating system •Kernel •Shell •Other Programs What businesses consider • • • • Cost Available Applications Ease-of-use Reliability Department of Child Support Services • County of San Diego – Operating System: • Windows XP Professional – Factors • COST • Reliability Cox Communications • Large cable, phone, internet, etc. company – Operating system: • Windows XP – Plan to upgrade to Windows 7 once it is proved to be a reliable Operating System – Factors: • Store extremely large amounts of information • Ease of use for employees • Cost Passage Productions • Film, video, and broadcast production company – Uses a combination of Mac OS and Windows OS • Offer different applications needed to run their business • Mac uses 64-bit platform, as does many of their platforms • Use Adobe – cross-compatible • Find Mac to be easier to use CSUSM • California State University – Operating System: • Windows Vista – Factors: • Cost • Ease-of-Use • Reliability – CSUSM stresses the importance of up-to-date technology Porter’s Five Forces Trends in OS • • • • Historical trends User’s Needs Competition (Macintosh vs. Windows) http://www.youtube.com/watch?v=FxOIebkm rqs Historical Trends -Manufacturing companies - Multiprogramming -1970’s Unix - Universities/Research Labs -Microprocessors -Graphical User interface User Needs • Language • Types of Users needs: -Programmer, business, personal, hacker. – Visual aids – Virus Protection – Malfunctions Macintosh & Windows • Personal vs. Business -Market share • Visual appeal • Popularity • Function/ Ease of use What does the Future hold? -New improvements -New Age in OS http://www.youtube.com/watch?v=yBqDpVqu IbI
