Research Question How can information theory be utilized to improve efficiency of communication and data storage in modern computing networks?
Literature Review Information theory: the backbone of modern communication. Before Claude Shannon published his groundbreaking paper A Mathematical Theory of Communication, information as a quantity was poorly understood. A Mathematical Theory of Communciation put forth the foundation of information theory, the mathematical study of information and its properties (Cruise, 2014e). Through information theory, scientists and mathematicians have created quantative measures of structural complexity, compressability, communication complexity, and information content, providing a scholarly way

Information Theory Entropy. In order to discuss information theory in relation to computer science, one must first understand the tenants of the theory. The primary keystone of information theory sits in Shannon 's definition of the amount of information a source generates, measured by Shannon 's entropy. Shannon’s entropy also defines the limit of compression of a message from a particular source, as data cannot be compressed beyond its information content without loss. As stated above, the entropy of an information source is H(x) = , or the negative sum across the entire message space of the probability of the ith symbol 's occurrence times the base 2 log of the probability of the ith symbol 's occurrence. Consider an information source that is randomly generating lowercase letters from the English alphabet. Since each symbol has an equal probability of (1/26), H(x) can simplify to , and since 26 and 1/26 cancel, the entropy of the source, or the amount of information it provides per symbol, evaluates to log2 1/26, or ~4.7 bits per symbol. Now imagine our source only transmits letters a-e, with probability increasing across the list, from 1/7 to ⅓. The entropy of the source evaluates to {-(1/7 log sub 2 1/7 + ⅙ log sub 2 ⅙ +

Introduction: Within this first task, of the assignment I will be discussing two different types of communication theories, which are the Argyles theory of communication and the Tuckman’s theory of communication. I will be discussing, what they both are, how they work and how they relate to and help within health and social care.
Information is made from Data that is numerical which is changed and used to make it seem sense. For an example train timetable, the number of trains and how much it weights.
This assignment will discuss two well known theories of effective communication. Firstly it will look at Michael Argyle (1972), the cycle of communication and then it will discuss Bruce Tuckman (1965) stages of communication.
- Information: is a knowledge which can be transferred or received concerning a particular fact or situation. And is a sequence of symbols that can be explained as a message. Information can be recorded as signs, or transmitted as signals.
Humans act toward people, things, and events on the basis of the meanings they assign to them. Once people define a situation as real, it has very real consequences. Without language there would be no thought, no sense of self, and no socializing presence of society within the individual. (Socio-cultural tradition)
Information is data that has been processed so that it has meaning and value to a recipient,
According to the Merriam Webster dictionary, entropy can be defined as “the degree of disorder or uncertainty in a system.” In his novel, The Crying of Lot 49, Thomas Pynchon manipulates the definition of the scientific term “entropy” to manifest the innate chaos and disorder in both a closed thermodynamic system and in the life of the protagonist: Oedipa Maas. In the novel, Oedipa Maas explores entropy with respect to the thermodynamic sorting of molecules in Maxwell’s Demon, and the communication information regarding the “Tristero”. According to Warren Weaver’s, Recent Contributions to The Mathematical Theory of Communication, there are technical, semantic, and effectiveness problems that may distort the accuracy of communication,
Information is data which is accurate and timely specific and organized for a purpose presented within a context that gives it meaning and relevance. Information can lead to an increase in understanding and decrease in uncertainty.
It is important to agree and commit to a strategy for communicating as a project team. Consider options. Having a communication strategy that people haven’t had an opportunity to agree on, or who aren’t aware of, will mean that communication won’t be effective.
Today, just about everyone depends on information and communication to keep their lives moving through daily activities like work, education, health care, leisure activities, entertainment, travelling, personal relationships, and the other stuff with which we are
However, according to Shannon himself, what really launched him into the theorization of information was Ralph Hartley’s paper Transmission of Information. This paper developed “a measure of information that could in principle be used for discrete or continuous signals.” Hartley’s publication also proved that a channel’s bandwidth defines how much information can be sent through it. Since a channel’s bandwidth was limited and since continuous signals could be broken down in small steps before being sent through the channel, Hartley concluded that if the steps were small enough, the approximated signal would be not only close but identical to the original signal. Finally, Hartley realized that information could be the “resolving of uncertainty.” He developed a mathematical formula according to this concept to quantify the amount of information in a message but unfortunately, this formula was not complex enough and could not be applied to cases in which the constituents of a message did not have all the same chances of being selected. Indeed, “in written English for instance, some letters are used more frequently than others.” Hartley’s formula would not work when trying to encode sentences for example because he couldn’t model the fact that the letter E had more chances to be selected than any other.
Intentionally or intuitively, we constantly use convergence and divergence in our daily communication routine. While the process itself is automatic; the manner of not doing either does not exist, because one of the two is always being chosen. Convergence is the process of adapting ones speech style to match others they want to identify and divergence is the use of linguistic mannerisms that emphasizes a person’s differences from others. A person would be able to understand these two concepts through personal examples by comparing and contrasting the differences in each term, discussing what aspects of these communicative techniques were conscious and which were
Communication is a way of life for sociable organisms on earth. There are many forms of communication and several are used without saying a word or making a sound. With the types of communication in the world, communicating effectively may seem an unlikely idea. Effective communication between two individuals or more is dependable on the way the message from the sender has encoded the information. Effective communication insists that information sent should be received and retransmitted back to the sender without any loss in translation. To understand communication, it must first be broken down so that each
Advancements in the information technology sector have brought many benefits to the people all around the world. Today with computer networking, we can chat, speak and see each other over a long distance. Data communication refers to the transmission of the digital signals over a communication channel between the transmitter and receiver computers. Communication is possible only with wired and wireless connectivity of the computers with each other.
