  1. Understanding Windows

  2. Learning Objectives • Differentiate among current versions of Windows • Know basic features, system requirements, intended users, uses of different versions of Windows

  3. Evolution of Windows O/S • Microsoft introduced Windows 3.x in 1983 (note 1) • Windows 95 was the first MS standalone O/S based on Graphical User Interface • Subsequent versions became the Win 9x including: Win 95A, 95OSR2, 98, 98 Second Edition, Millennium Edition (note 2)

  4. Windows 95 • New naming system (no more version numbers) • Aimed at individual consumers but became popular with businesses • No new copies are sold anymore • Original was OSR1 • OSR2 only available as OEM product

  5. Windows 98 • Improved usability and address system problems: • Plug-and-Play technology (note 1) • No need to set jumpers and direct memory access channels • Added support for new hardware standards like USB • New support tools (note 2) • Integrated browser with O/S (note 3)

  6. Win Me • Introduced in 2000, new naming convention • Integrated with the internet • System can be updated over the internet form Microsoft website • Configuring the computer for a LAN simplified through wizards • Most important update was feature called System Restore

  7. Windows NT • NT 4.0 released 1996 • 32 bit GUI O/S • Scalability + Security • Either stand alone or server platforms…small networks to enterprise servers • Win 2000 and XP share the same core structure, files and features • NT is the only MS O/S to offer SMP

  8. Win 2000 Professional • Desktop version • Single User • Dual CPU (SMP) • File encryption of sensitive data • Advanced troubleshooting tools • Supports NTFS5 • Mobile computing ability

  9. Win 2000 Server • Entry level server platform, replaced NT Server • Extends SMP to 4 CPUs/machine • Active Directory (domain naming service)

  10. Win 2000 Advanced Server • Support for up to 8 CPUs, 8 GB RAM • Server clustering • Designed for busy networks and e-commerce sites

  11. Windows 2000 Datacenter Server • Designed for large data warehouses, large scale Web farms • Supports 4 way clusters • Storage area networks

  12. System Requirements • RAM • Processor Speed • Graphics card • Storage space

  13. RAM • You can never have too much RAM • In 32-bit system, additional RAM always boosts performance • Cheapest and easiest way to improve speed and performance is to add RAM

  14. CPU • General purpose applications: minimum CPU speed required • Should have good graphics card with its own processor • Graphics intensive applications or multitasking requires more speed • Step up in RAM bigger boost than jump in CPU speed

  15. Graphics Card • Power of processor affects refresh rate, resolution, color

  16. Storage • While upgrading, hard drive should have enough capacity to store both new O/S and upgraded applications (Office 2003)
