Introduction to Computer Hardware Case Power switch Reset switch Hard drive Floppy CD/DVD Zip drive Serial ports Parallel port USB port Keyboard/mouse Network card Modem Sound card Video card RAM Motherboard Bus Fan Cables

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 and DVDs, Oh my!

Three most important words in computing. 1.Backup 2.Backup 3.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 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.)

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? Computer Troubleshooting and Maintenance Tutorial
