Cabling
10
For items in or attached to a system to work
properly they must be securely connected.Be
sure to carefully connect the cables.
11
Basic operations
  • Power cord plugged in.(If plugged into a power
    strip, turn it on. Includes peripherals.)
  • Cables to peripherals secure.
  • Power on peripherals.
  • Power on the system.
  • Observe the system for proper operation.

12
The basic system including keyboard, mouse and
monitor.
13
Operating systems
  • All computer systems have an operating system.
    Currently (09/01), there are three dominate
    typical user operating systems. (Macintosh OS,
    Microsoft Windows OS and Linux.)

14
FYI Disk capacities
  • Floppy(Double Sided, Double Density)
  • Zip cartridge
  • CD
  • DVD(Single Sided, Single Layered) (Double
    Sided, Double Layered)
  • 1.4 MB
  • 100 MB 250 MB
  • 650 MB
  • 4.7 GB
  • 17 GB

1 GB 1000 MB
15
Floppies, zips, CDs and DVDs,Oh my!
16
Three most importantwords in computing.
  • Backup
  • Backup
  • Backup
  • You should backup when you do not want to reenter
    everything you have entered since your last
    backup. (Schedules can range from every item to
    months.)
  • You should regularly check that your backups
    work.
  • Multiple backups and off-site backups are often
    required.

17
Other good ideas.
  • Anti-virus software.
  • Regularly updated virus definitions for the
    anti-virus software. (Automated if available.)
  • Current security patches applied to operating
    system and applications.
  • Scrutinize any unexpected attachments that are
    e-mailed to you. (Particularly .vbs and .exe
    files.)

18
Fast and Furious TroubleshootingBefore you
call
  • Is it plugged in? Is it turned on?(Also, Is
    the power on in your building?, etc)
  • Have you tried rebooting the system.(Exiting
    correctly and physically powering down the entire
    system including peripherals.)
  • Can you reproduce the problem on-demand?
