Guided media includes Twisted Pair, Coaxial, and Fiber Optic. Unguided media includes terrestrial microwave, satellite microwave, radio and infrared technologies (Warner, 2008). The security strategies for each class of media must taken into account how each codes, decodes and manages the stream of data across these media types.
For guided media there are several levels of security including access, protocol stability and security, locking data elements and packets, and the use of Cyclic Redundancy Checking (CRC) for accuracy and authentication of specific access points,. These media also require the use of protocols that can be used for protecting down to the packet level data being transmitted. The reliance on advanced TCP/IP protocols and options is a case in point.
For unguided media the challenges are more significant as these are by nature broadcast technologies. The protocols that these networks transmit must be protected down to the packet and frame level, including adoption of IEEE 802.11b security authentication...
Disney is an excellent example of this -- it produces children's cartoons, children's and adult films, hosts several theme parks, publishes books, videos, and toys, as well as owns ABC. Vertical integration, within its sphere, seems most immediately damaging to competition. Google has effectively vanquished its competition within the search engine market. Disney has considerable competition in the sphere of network programming with CBS and NBC, and other movie studios

Business communication is mainly used to promote or market an organization as well as its products and service since it incorporates the steady flow of information. Additionally, business communication is not only used in transmitting information within a business but is also used in relaying information between a supply chain. While the supply chain basically consists of the consumers and the manufacturer, business communication is also used to tackle legal
Business Intelligence Unlike its Military counterpart, Business Intelligence is not an oxymoron. There are many examples of successful implementations of Business Intelligence despite the challenges. This paper explores the purposes for and the complexities of data processing systems that are designed to provide tools for top managers in their task of wading through swamps of unrelated information as they hone in on supports for taking critical business decisions. A possible confusion of
" According to Short, Williams, and Christie (1976; cited by Van Den Hooff, Groot & De Jonge, 2005), Social Presence Theory notes that "communication media differ in the degree to which they can communicate (or simulate) the social presence of the communication partners through the use of social cues (both verbal and nonverbal cues)." This theory purports that if a medium can only communicate limited social cues, communication partners do
Employees become frustrated and develop negative views concerning management. Any animosity that the employee may exhibit could result in workplace violence. If employees are terminated or laid off under such conditions, resentment could lead to violence (Chenier 1998)." stressful work environment can also lead to poor service and customer dissatisfaction (Waner 1995). In severe cases, problems communicating in the workplace can lead to the demise of a business or
