INTRODUCTION: A local area network (LAN) is a network of computers that interconnects computers in a limited or a small area such as a home‚ computer lab‚ school‚ or office building using the network media. The defining characteristics of LANs‚ is in contrast to the wide area networks (WANs)‚ including their higher data-transfer rates‚ smaller geographic area‚ and lack of a need for leased telecommunication lines. ARCNET‚ Token Ring and other technology standards have been used in the past‚ but

Due to the rise in demand for wireless sensor networks in recent times‚ significant shift is observed from traditional‚ wired technologies to upcoming wireless technologies. Asia-Pacific is expected to grow at the highest rate due to increase in production activities in APAC‚ huge population base‚ and lucrative government policies. China is‚ in fact‚ the growth engine for automation in Asia-Pacific; in spite of lower levels of plant automation. India is also gaining market shares worldwide.The WSN

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
