Transcript

  • 1. Technologies – Week 5LIS 3353 Spring 2012 – 1/30/12
  • 2. Strategy (week 5)Agenda IT News 5 week check in Slides for week 5 – Strategy – Sourcing – Hardware (Power Supply, Hard Drive) Assignment
  • 3. Strategy (week 5)IT News
  • 4. Strategy (week 5)Life Cycle
  • 5. Strategy (week 5)Life Cycle
  • 6. Strategy (week 5)Life Cycle Life Cycle Issues – The embryonic stage can sometimes be skipped – Industry growth can be revitalized – The time span for each stages can vary – Complementors can affect the cycle
  • 7. Strategy (week 5)Life Cycle Innovation and Change – Innovation can unfreeze and reshape the industry structure – New competitors can change the industry – Defining a “new” segment of the industry is very difficult, especially with technology overlap
  • 8. Strategy (week 5)Life Cycle Performance Maturity Growth Time Intro
  • 9. Strategy (week 5)Things to remember Short history (see life cycle) Evolving field 2-3 year window IT skills degrade proportionally to changes in technology IT is a tool that evolves – you need to continually adapt and position yourself and your business
  • 10. Strategy (week 5)Life Cycle
  • 11. Strategy (week 5)Life Cycle
  • 12. Strategy (week 5)Life Cycle
  • 13. Strategy (week 5)Life Cycle
  • 14. Strategy (week 5)Sourcing Definitions of Sourcing – Sole sourcing – Internal sourcing (insourcing) – External sourcing (outsourcing) Outsourcing – Onshoring – Nearshoring – Offshoring
  • 15. Strategy (week 5)Sourcing Relate sourcing to Web 2.0 – Crowdsourcing • Asking friends to help with promotion • Mozilla Firefox – People sourcing • C2B
  • 16. Strategy (week 5)Crowdsourcing Relate sourcing to Web 2.0 – Crowdsourcing – People sourcing • C2B
  • 17. Strategy (week 5)People Sourcing
  • 18. Strategy (week 5)People Sourcing
  • 19. Hardware (week 5)Operating Systems Lower level A program that controls the execution of application programs and an interface between applications and hardware Primary Functions – Control – Error detection and response – Accounting
  • 20. Hardware (week 5)Operating Systems Buffer between hardware and user
  • 21. Hardware (week 5)Operating Systems Outside world Video Hard drive USB Network controller controller controller controllerCPU Computer internals (inside the “box”) Memory
  • 22. Hardware (week 5)Operating SystemsControl: Program development Editors and debuggers Program execution Access to I/O devices Controlled access to files System accessError detection and response: Internal and external hardware errors (Memory error, Device failure) Software errors (Arithmetic overflow, Access forbidden memory locations)Accounting: Collect usage statistics Monitor performance Used to anticipate future enhancements Used for billing purposes
  • 23. Hardware (week 5)OS TimelineFirst generation: 1945 – 1955 Vacuum tubes Plug boardsSecond generation: 1955 – 1965 Transistors Batch systemsThird generation: 1965 – 1980 Integrated circuits MultiprogrammingFourth generation: 1980 – 2005 Large scale integration Personal computersNext generation: 2005 - Systems connected by high-speed networks Wide area resource management? Cloud computing
  • 24. Hardware (week 5) OS Functions Other Tasks – Memory management: allocate main memory among several processes – Swapping: move processes and their data between main memory and secondary storage – I/O device drivers: specialized code required to operate I/O devices – File system: organize mass storage (disk) into files and directories – Utilities: date/time, accounting, file copy, etc.
  • 25. Hardware (week 5) OS Functions Other Tasks – Command interpreter: allow users to enter commands interactively – System calls: allow user programs access to O.S. services – Protection: keep processes from interfering with each other and system – Communication & Resource sharing: allow users/processes to communicate (over networks) and share resources (e.g., laser printers, disks, etc.) – Security: protect machines from intruders, worms and viruses
  • 26. Hardware (week 5)OS Functions CPU scheduling: allocates computing time among several processes – Operating systems manage processing tasks – Multi-tasking - allows more than one program or person to use the resources of a single processor at the same time. – The use of a processor by more than one user is referred to as time sharing. The operating system accomplishes time sharing by dividing processor time into “timeslices” which are very brief time slots. Increases usage of processor.
  • 27. Hardware (week 5)OS Functions Simplify the execution of user programs and make solving user problems easier. Use computer hardware efficiently. – Allow sharing of hardware & software resources. Make application software portable Provide isolation, security and protection among user programs. Improve overall system reliability • error confinement, fault tolerance, reconfiguration.
  • 28. Hardware (week 5)OS FunctionsIn Summary – Control common hardware functions – Control access to system resources – Provides a user interface – Manage files – Manage system memory – Manage processing
  • 29. Hardware (week 5)Types of OperatingSystems + Windows Vista + Mac OS 10.5 (Leopard) + Mac OS 10.6 (Snow Leopard) + Windows 7 + Mac OS 10.7 (Lion) + Windows 8
