a supply of good, clean filtered air. Frequently cleaned systems which operate in a dirty, dusty, or smoky environment. EMI 0:42-0:59 Protect your systems and network cabling from electromagnetic interference, or EMI. EMI is generated by motors, machinery, and even fluorescent lights. You can use shielded cables or run your network cabling in conduit to prevent EMI. Fiber optic cable is not susceptible to EMI. RFI 1:00-1:19 Radio frequency interference, or RFI, can disrupt wireless network traffic. RFI can be generated by cordless phones and other home automation hardware. Wireless networks that operate within the 2.4 gigahertz range are particularly susceptible to RFI. This can be overcome by moving to a wireless solution that operates in the five gigahertz range. Magnetic Fields 1:20-1:34 Data stored on magnetic media like disks and tape is at risk from any source of a magnetic field, such as speakers, motors, and fans, and even space heaters. Solid state and flash storage devices are not susceptible to this kind of data loss. Cleaning Computers 1:35-2:37 Proper computer maintenance includes periodic cleaning. Dust and dirt will insulate PC components,trapping heat and shortening the life of your computer. Some common cleaning supplies include a lint-free cloth, compressed air, an antistatic and micro filtering vacuum cleaner, and denatured alcohol, or isopropyl alcohol. Always power down the system before cleaning, and use caution with liquid based cleaners. Never apply a liquid directly to a PC component. You'll used the denatured alcohol to clean electrical contacts. Use a dry lint free cloth, or a special LCD cleaning solution to clean LCD screens. Keyboards should be cleaned with a small PC vacuum cleaner, or compressed air. Inkjet print heads should be cleaned with a manufacturer's supplied utility. Excess toner should be removed from a laser printer with an antistatic and micro filtering vacuum. And lastly, use only a special cleaning disk and its related software to clean CD or DVD drives. CD and DVD disks can be cleaned with a soft dry cloth. Maintaining Computers 2:38-3:04 Here are a few more considerations to help you ensure a long life for your PC components. When you receive a component that has been shipped to you, allow it to sit at room temperature for at least six hours. This will dissipate any condensation that may have been caused by a rapid change in temperature or humidity. Use covers and cases to protect equipment when it's not in use. Use cable ties and anchors to keep cabling organized, and always perform regular backups of important data. Summary 3:05-3:16 That's it for this lesson. We discussed several different things you can do to extend the life of your computer equipment, like maintaining proper temperature and humidity, protecting your systems from interference and magnetic fields, and cleaning your PC 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.

    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.
