QUESTION1 Power Problems Alternating current (AC)‚ which is “food” to PCs and other network devices‚ is normally 110 volts and changes polarity 60 times a second (or 60 Hertz). These values are referred to as line voltage. Any deviation from these values can create problems for a PC or other network device. Power problems fall into three categories: * Overage * Underage * Quality Power Overage Problems During a power overage‚ too much power is coming into the computer. Power overage

The way ones and zeros are physically carried through a specified network depends on whether the network is electrical‚ optical or radio. In electrical networks‚ one bits are represented as high voltage‚ and zero bits are represented as a low voltage. In optical networks‚ one bits are represented by the presence of light‚ and zero bits are represented by the absence of light. The ones and zeros are carried through the network‚ and the receiving device repackages the ones and zeros to determine
