  1. Operating Systems Review

  2. 5 Purposes of an Operating System • Provide User Interface • Communicate with Hardware • Create and Manage a File System • Network Support • Provide Structure to Support Applications

  3. Installation

  4. Partitions • Every disk needs at least 1 partition to install an operating system • Formatting a partition will allow you to install an operating system (NTFS, FAT16, etc) • Max Number of Partitions on Basic Disc is 4! • Primary and Secondary Partitions • Active Partitions

  5. Active Partitions • This is where the OS system files are • Motherboard looks for the active partition to begin running or booting the OS • boot.ini is the file that windows uses to declare where the systems are.

  6. Extended Partition • Doesn’t hold an operating system • Basic Disc • Logical Drives • Basically large named folders in the Extended Partition

  7. Basic vs. Dynamic Disks • Uses NTFS or FAT32 file systems • Can create primary partitions or active partition • Dynamic Disk – unknown file system (Microsoft won’t tell anyone how it works)

  8. File Systems • NTFS • FAT16 • FAT32

  9. FAT16 • The Primary Partition can only be up to 2 GB • File names can only be 8 characters • File extensions can only be 3 characters

  10. FAT32 • 32 GB Size Hard drives (Basically) • Used mostly with Windows 98, 2000 and some XP • No security available

  11. NTFS • New Technology File System • Nice long file name and extensions • Supports file encryption (You still have to have at least XP Pro) • Most common file system used today

  12. Windows Requirements • Size of Disk Space • RAM • Processing Speed/Processor • Video/Monitor Support

  13. Windows XP Requirements • Minimum • 233 MHz Processor • 64 MB RAM • 1.5 GB HDD Space • CD-ROM/DVD-ROM • Super VGA (800 x 600) • Recommended • 300 MHz Processor • 128 MB RAM • 1.5 GB HDD Space • CD-ROM/DVD-ROM • Super VGA (800 x 600)

  14. Windows Vista Requirement • Home Basic • 800 MHz Processor • 512 MB Memory • Direct X (graphics api) • 20 GB HDD Space • DVD drive • Other Versions • 1 GHz Processor • 1 GB System Memory • Direct X • 40 GB HDD Space • DVD drive

  15. Windows 7 Requirements • 32 Bit Processor • 1 GHz Processor • 1 GB RAM • 16 GB HDD Space • Direct X9 • 64 Bit Processor • 1 GHz Processor • 2 GB RAM • 20 GB HDD Space • Direct X9

  16. Installation Menu • Options • Install • Repair • Exit

  17. Installation process • Partition the Drive • Format the Partition • Unpack the Installation Files • Install the Operating System • Set – up Time and Date and Language • Enter your Product Key • Set-up an Administrative User • Activate ? • If you don’t activate Windows, after 30 days you are locked out

  18. Serial Number • CD Key • Product Key • This is used to unlock your software

  19. Activation • Must be done with in 30 days or you are locked out • Activate over the internet if you have an internet connection • Active by calling their 1-800 number with your product key

  23. Display • Screensaver • Desktop • Background Picture • Settings • Resolution • Dual Monitors • Appearance • Colors of windows, etc.

  24. System Settings • This is your basic System Properties • You can also get to this from right-clicking My Computer • See your RAM, CPU, and OS properties • Device Manager • Remote • Get to Remote Assistant and Remote Desktop Settings

  25. Power Options • Power Schemes • Alarms • Power Meter • Advanced • Hibernate

  26. Power Schemes

  27. Advanced – Power Options

  28. Hibernate – Power Options • Save the state of the computer to the hard drive and shuts everything down.

  29. Users • Standard • Can install • Can’t mess with System files • Restricted • Can’t Install Programs • Power User • Have most administrative priviledges • Administrator • Complete Unrestrict access • Guest • Like a Standard user, no saving though

  44. Troubleshooting

  45. BSOD • Blue Screen of Death • Boot Error or RAM Error • Restart Computer • Recovery Console – DOS console that you can boot to from the Windows installation disk • FIXBOOT – fixes boot.ini • FIXMBR – fixes master boot record

  46. Viruses • A file that replicates itself • Has to be run – usually found in email attachments and shared files through peer-to-peer networks • Trojan – a program that is doing something in the background you don’t want (Trojan Horse) – use a Firewall or don’t download illegal material. • Worm – like a virus, but you don’t have to run it to get it. If you connect to a network that has it, you’ll get it

  47. Start Up Services • In MSCONFIG • You can enable or disable certain services • Start up in Safe Mode – no services running

  48. Remote Desktop • Unblock FireWall • Connected on the network to the remote computer • Know a user account and password on that computer • Start -> All Programs -> Accessories -> Remote Desktop Connection • Gives you control of the machine, blocks the user out
