Energy can not be created or destroyed‚ but it can be transformed: the first law of conservation of energy. Since the earliest days of humanity‚ man has always been trying to control energy. It was not till the last century when Humans finally learned to harness the high concentration of energy existent in fossil fuels. Energy sources from fossil fuels such as oil and gas are going to run out eventually‚ they are non renewable sources of energy. Even though humans achieved to apply the first law

Lesson 5 Review: Networking Models‚ Traffic and Devices The purpose of this activity is to reinforce what you have learned so far about local area networks technologies. 1. Describe the three modes of communication available on a network. Simplex Data travels in only one direction‚ similar to a public address (PA) system. Half-duplex Data travels in two directions‚ but in only one direction at a time‚ similar to a walkie-talkie. Traditional shared Ethernet uses half-duplex transmissions.
