  70. Define APM, then list and define its levels- APM is Advanced Power Managment.
    Full On: Evertying in the system is running at full power. There is no power managment.

    Standby: CPU is stopped. RAM still stores all programs. All preipherals are shut down, although configuration options are still stored. (In other words, to get back to "Enabled" you won't have to reinitialize the devices)

    Suspend/Hybernation: Everything in the PC is shut down or at its lowest power-consumption. Many systems use Hibernation, which is a special kind of Suspend where the programms in the RAM are written to a hard drive. Upon a "wake up" event, the system is reinitialized, and the data is read from the drive to return the system to "Enabled"

    •      S3: Sleep or Standy mode. Power to Ram still on.
    •      S4: Hibernation mode. Information in RAM is stored on      
    •             nonvolatile memory or drive and powered off.
    • G2(S5): Soft power off mode. Certain devices used to wake a system (keyboards, LAN, USB) remain on, while most other components are powered to a mechanical off state (G3)
    • G3: Mechanical Off Mode. The system and all components other than the RTC (real time clock), are completley powered down.

    Charge: To make the drum take an image, it is given a negative charge with the Primary Corona of between ~600-~1000 volts.

    Write: A Laser is used to write a positive image on the drum. Particles of the drum hit by the laser have their negative charger lessened, giving it a positive charger relative to the toner.

    Develop: The charge between the Laser hit particles on the drum and the charge of the toner attracts toner particles to the Laser hit areas creating a developed image.

    Transfer: The Transfer Corona gives the paper a positive charge, attracting the negatively charged toner particles causing them to leap from the drum, to the paper.

    Fuse: The plastic toner particles are melted into the paper using two rollers. One roller applies pressure (the "Pressure Roller") and the Heated Roller is coated in a non-stick material (like Tephlon) and melts the toner into the paper.
