Please explain the components below and include pictures (make sure you cite correctly).

  • Safety and Environmental procedures

    • ESD

      • Short for ElectroStatic Discharge, ESD is one of the few things an individual can do to damage or destroy his or her computer or hardware components.
    • EMI

      • Short for electromagnetic interference, a naturally occurring phenomena when the electromagnetic field of one device disrupts, impedes or degrades the electromagnetic field of another device by coming into proximity with it.
        • Network interference- when waves cannot reach out and get a connection, or when something is interfering with the connections connectabllity
        • Magnets-
    • RFI

      • Radio Frequency Interference- This could involve interference to a neighbor's equipment, or, more likely, some form of intererence to Amateur Radio from the noisy devices that can sometimes even be found in our own homes.
      • Cordless Phone Interference- Over the phone while someone is using the internet can cause this to happen. Static will being to interrupt your call and maybe be unable to hear or dial the person you are trying to contact.
      • Microwaves- they can also send off waves to interrupt your internet connection

Computer Cleaning Procedures

  • Info From Here -(
    • Do not leave a computer plugged in while cleaning unless you are certain there is not a "wake" feature that could activate.
      • The computer may turn on while you are cleaning or repairing it and cause damage to itself or you. Instead, unplug all electrical items before working on them.external image simpsons_electrical_safety.gif
    • Never spray cleaning liquids directly unto any part of your computer.
      • Because if the liquid make contact with any part of your computer may cause sensitive electronic equipment to malfunction, or corrode. Instead of spraying the liquids directly onto the computer, try spray liquids unto your cloth or whatever you are using to clean and then wipe the away dust and grime from non-sensitive surfaces.
    • Do not spray canned compressed air with the can upside down.
      • Because instead of the air coming out the can, you might get liquid air and that will damage or ruin the computer components. So, do not flip the can upside down always keep the can striagth up and shoot out small burst of air.
    • Do not touch any internal CPU component without wearing an anti-static wrist band or using an anti-static mat.
      • Because static is one of the greatest enemy's to sensitive equipment. A small static shock can ruin your computer, and plus all the static the generates in the human body will kill it in a blink of an eye. Start wearing an EST(anti-static wrist strap) strap instead, wear a properly grounded anti-static wrist strap or work on an anti-static mat. At the same time, keep the computer on a stable platform above the floor.
    • Do not use a standard vacuum to clean inside your computer.
      • Because if you use an normal vacuum to clean it, all the static electricity will gather up and it will kill your computer, even on accident. Start using the vacuums that are recommended for cleaning computers, or just don't use a vacuum at all.
    • Do not attempt to clean the inside of a computer monitor.
      • Because it migth have high voltage once unplugged. Instead of you trying to clean it just leave the job to a professional.
    • Do not touch an lcd screen with your fingers.
      • You may short out the pixels and ruin it. Instead, use a soft anti-static, lint-free cloth as recommended by the manufacturer to clean dust and debris from the screen.
    • Do not use an unapproved liquid to clean your lcd screen.
      • The wrong solution may remove or damage special anti-glare coatings on the screen. Instead, use the liquid cleaner recommended by the manufacturer.
    • Clean up the general area surrounding your computer before beginning.
      • It wouldn't make sense to leave dust and dirt in the area to get sucked back into your computer after it is cleaned as well as re-contaminate the external parts. Moving the equipment around will stir up surrounding dust, allowing it to settle in and around your computer.
  • Cable Management

    • Cable Management is the subsequent installation of equipment providing means to tidily secure electrical, data, and other cables. Try making you cable's run in places that can't be visible and places that you won't trip on them.
  • Material Safety Data Sheets (MSDS)

    • Its is meant to be a sheet that workers and emergency personnel use to find the right procedure for the right situation that might require them to work with substance in a safe way, That includes information such as, physical data (melting point, boiling point, flash point, etc.), toxicity, health effects, first aid, reactivity, storage, disposal, protective equipment, and spill-handling procedures.
  • Physical safety

    • Eyes
      • Staring into your screen for to long can and will cause eyestrain, effects may be headaches, blurred vision and itchy, scratchy eyes. Start looking away from you computer like every 30seconds to give your eyeballs a rest. Also switch out your contacts for glasses whenever possible.
    • Back
      • Keep a good posture is a excellent way to get back pains away. Sitting on your bed or sitting on the ground seems easier but it puts pain onto your back. The best way to sit is in a chair with your feet on the ground. Also get up and walk around for a bit, atleast once an hour.
    • Hands
      • Typing on a computer keyboard requires you to repeat the same motion over and over, this causes inflammation called Carpel Tunnel Syndrome. Place your keyboard on a slight angle and shake out your hands in-between thoughts.
    • Neck
  • Recycle Your Equipment
