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

communicate successfully. IEEE 802.11 is a set of standards for implementing wireless local area network (WLAN) computer communication in the 2.4‚ 3.6‚ 5 and 60 GHz frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). The base version of the standard was released in 1997 and has had subsequent amendments. These standards provide the basis for wireless network products using the Wi-Fi brand. The most prevalent is 802.11b. Equipment using

Later the Arabs built roads that were covered with tar. The roads were constructed by preparing earthworks and lifting road foundation at the center for the water drainage. The road construction techniques gradually improved by the study of road traffic‚ stone thickness‚ road alignment‚ and the slope gradients. The initial road construction materials were stones that were laid in a regular‚ compact design‚ and covered with smaller stones to produce a solid layer. Depending on the main function‚
