Cabling
For items in or attached to a
system to work properly they
must be securely connected.
Be sure to carefully connect
the cables.
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.
The basic system including keyboard,
mouse and monitor.
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.)
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
Floppies,
zips, CDs

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.
Other good ideas.
• Anti-virus software.
• Regularly updated virus definitions for the antivirus software. (Automated if available.)
• Current security patches applied to operating
system and applications.
• Scrutinize any unexpected attachments that are emailed to you. (Particularly “.vbs” and “.exe”
files.)
Fast and Furious Troubleshooting
“Before 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?
