One of the most important things you can do to keep computer systems running is to create the proper environment. Consideration Description Heating, ventilation, and air conditioning (HVAC) For computer components, design HVAC systems with the following in mind: Keep temperature between 70 and 74 degrees to prevent components from overheating. Keep humidity between 40 and 70 percent to prevent electrostatic discharge (ESD). Make sure server rooms have separate ducting or HVAC systems from the rest of the building for better temperature control. Use positive pressure systems. Positive pressure systems protect the air quality in the facility by causing air to be forced out through doors, windows, and other openings. Negative pressure systems draw air in, potentially bringing in airborne particles such as dust or smoke. Positive pressure systems are more energy effective. For areas with heavy smoke or dust, add filters to air intake systems to filter out airborne particulates.

Interference Interference is a signal that corrupts or destroys regular signals. Interference affects signals used by two devices to communicate on a network. Listed below are two types of interference that affect computer networks: Electromagnetic Interference (EMI) EMI is interference that affects wired networking signals. EMI is caused by motors, heavy machinery, and fluorescent lights. Use shielded twisted pair cable to protect signals sent on Ethernet twisted pair cabling. If necessary, use fiber optic cables to eliminate the effects of interference. Radio Frequency Interference (RFI) RFI is interference on the radio channel used by wireless networking devices. RFI can be caused by nearby wireless devices using the same channel, cordless phones, or microwave ovens. Wireless networks that use the 2.4 GHz frequency range (801.11b and 802.11g) are susceptible to RFI. RFI can be reduced by using a wireless networking standard that operates in the 5.75 GHz range or by using a different channel for wireless devices. Magnetic fields Magnetic fields located close to a computer can cause undesired effects or even data loss. Hard drives and tape storage devices use magnetic charges on a disk or tape for storing data. While hard disks are shielded and protected from all but the strongest magnets, be careful with tapes. Getting a magnet too close to these components could erase data. Speakers, motors, and generators contain magnets (keep sensitive components away from these devices). Solid state storage devices (such as RAM or flash drives) are not affected by magnetic fields. One of the best things you can do to keep your system running efficiently is to keep it clean. Be aware of the following facts about cleaning your computer: Common computer cleaning supplies include: o Lint free cloth o Compressed air or air compressor o Small anti-static vacuum o Denatured or isopropyl alcohol Regular, periodic cleaning gives you the chance to inspect all components. Look for worn or failed components. On electrical components,

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
