PoE: A Success Story In the process control industry‚ two sets of wires – one for communications and the other for power- were utilized. This‚ however‚ is quite costly and impractical. It didn’t take long enough for engineers‚ being ingenious species1‚ to find a way to alleviate the growing need; thus‚ challenging them to find an answer to how structured cabling could be more economical and still efficient at the same time. And so the concept of Power over Ethernet (PoE) was born. This paper provides

a mile • Is fast‚ with speeds from 10 Mbps to 10 Gbps • Requires little wiring‚ typically a single cable connecting to each device • Has lower cost compared to MAN’s or WAN’s Local Area Network (LAN) • LAN’s can be either wired or wireless. Twisted pair‚ coax or fibre optic cable can be used in wired LAN’s. • Every LAN uses a protocol – a set of rules that governs how packets are configured and transmitted. • Nodes in a LAN are linked together with a certain topology. These topologies include:

a quality of being a reliable person to others when they are in a time of need. For example‚ my brother has had countless times where he just can’t get that darned lid of the peanut-butter jar. Luckily for him‚ I had been a reliable resource and twisted the lid off for him. Like I have helped my brother in the past‚ my parents have used me as a reliable “helper” in the family. Even though I am occasionally a reliable person when it comes to chores there are always times when my parents think lesser

Bacteria‚ zebras‚ mosquitoes‚ anacondas‚ essentially all living things have one thing in common which makes them what they are. It is DNA. It is one of the greatest biological discoveries in the history of mankind. It is not only related to biology but is tied to the study of chemistry as well because of the convoluted molecular structure. DNA is short for the molecule deoxyribonucleic acid. RNA or ribonucleic acid is another nucleic acid derived from DNA and used as a template to make proteins‚

Humans give their children twenty-three chromosomes from each of the parents. DNA looks something like a twisted staircase‚ and when in a condensed form‚ each DNA molecule is called a chromosome. Genes are formed in pairs are located in these chromosomes. During reproduction the gene pairs are split apart and randomly passed on to the offspring. During the replication of the gene pairs chance events such as mutations‚ can change their structure and prompt evolution. Through human interference

INTRODUCTION 1._Background Information For thousands of years human beings have been fighting in battles‚ always trying to find new ways of killing each other and winning. Combat was getting more and more sophisticated and human force was not sufficient enough to conquer a castle or destroy a ship. That was the time when ancient engineers introduced siege warfare‚ when “simple yet complicated hurling machines that rely on the fundamentals of math and physics using levers‚ force torsion‚ tension
