PCs within a physical area to form what is known as a local area network (LAN) A LAN connects network devices over a short distance Common applications include offices, schools, and the home Sometimes businesses are composed of several LANs that are connected together Besides spanning a short distance, LANs have other distinctive attributes LANs typically are controlled, owned, and operated by a single... That Led to Wireless Wireless technology is the method of delivering data from one point to another without using physical wires, and includes radio, cellular, infrared, and satellite A historic perspective will provide you with a general understanding of the substantial evolution that has taken place in this area.The common wireless networks of today originated from many evolutionary stages of wireless. .. serve as the basis of modern electromagnetic technology Around the same time that Faraday worked with electromagnetism, an American professor named Joseph Henry became the first person to transmit a practical electrical signal As a watchmaker, he constructed batteries and experimented with magnets Henry was the first to wind insulated wires around an iron core to make electromagnets Henry worked on a theory... electrical and magnetic waves from wires and radiate Hertz served as inspiration to other researchers who scrambled to duplicate his results and further develop his findings Inventors from all across the world easily validated Hertz’s experiments, and the world prepared for a new era in radio, the wireless transmission of electromagnetic waves An Italian inventor called Guglielmo Marconi was particularly... Michael Faraday, an English scientific lecturer and scholar, was engrossed in magnets and magnetic effects In 18 31, Michael Faraday theorized that a changing magnetic field is necessary to induce a current in a nearby circuit.This theory is actually the definition of induction .To test his theory, he made a coil by wrapping a paper cylinder with wire He connected the coil to a device called a galvanometer,...
