1. Describe the three basic characteristics of changing external environments • Environmental change is the rate at which a company’s general and specific environments change. If the environment is stable‚ this means that the rate of change is slow; if the environment is dynamic‚ this means that the rate of change is fast. • Environmental complexity is the number of external factors in the environment that affect organizations. Complex environments have many environmental factors; simple environments

ELECTRONIC COMMUNICATIONS SYSTEMS Wayne Tomasi‚ 5th edition Introduction to Electronic Communications Electricity began in 1837 when Samuel Finley Breese Morse invented the first workable telegraph. In 1894‚ Marchese Guglielmo Marconi successfully transmitted the first wireless radio signals through Earth’s atmosphere. In 1906‚ Lee DeForest invented the triode vacuum tube. Commercial radio broadcasting began in 1920 when radio station KDKA began broadcasting amplitude-modulated

information according to Shannon is equal to entropy. 8 http://communicationtheory.org/shannon-and-weaver-model-of-communication/ Says what? In which channel? To whom? With what effect? Who? 10 Redundancy- is the opposite of information. Something that is redundant adds little‚ if any‚ information to a message. Redundancy is important because it helps combat noise in a communication system‚ e.g. in repeating the message. A code- is a language or other set of symbols or signs that can be used to

Communication system denotes the ways and means of movement of people and goods from one place to another inside a country and outside it as well. In other words it refers to the transport facilities that are available to people for traveling and carrying goods. It includes both the vehicles and the ways used by them. The history of the development of transport shows how people have been trying from prehistoric times to use more and more advanced types of transport thereby replacing the traditional
