What is communication - Essay Example ation on the other hand does not incorporate the use of symbols in the communication but it considers all the verbal exchange between two or moirà © parties as communication. The oxford dictionary traces the origin of the word ‘communication’ to the Latin word communis meaning â€Å"common† and Reuben and Stewart believe that the first form of communication originated in the Greek empire especially by the early philosophers like Aristotle and Socrates who developed different explanations concerning communication. These two explanations of communication resemble the Schramm’s model of communication in that they all realize the importance of understanding between the sender of the information and the receiver. In Schramm’s model he calls it the ‘commonness’ between a source and the receiver. All the parties in the communication channel must understand one another and this can only be measured through a feedback from the receiver (Ruben & Lea 20). The transactional model of communication is a preferred model because the communicators can act simultaneously by sending and receiving messages and that the communication process in this case is dynamic and it changes over time. In this model the people whom you are communicating with keep on changing as well as the environment in which the communication is taking place. This model enables the parties involved to gain understanding of the information being communicated because the two parties are interdependent thus the source cannot relay information without the receiver and vice versa. The several factors that affect the reaction of both the sender and the receiver are factors like their cultural beliefs, self esteem and their own backgrounds (wood, 6). My own model of communication would be a linear model that will enable the receiver to give feedback of the received information. This model will be effective than any other in the textbook since the linearity of this model will enable the receiver to listen

RFID and the safety concerns of consumers Essay

RFID and the safety concerns of consumers - Essay Example RFID systems are also faster and more secure than other Auto-ID technologies. Even though RFID tags were invented in 1969 and patented in 1973, the technology is now becoming technologically and commercially viable (Brito, 2005). Understanding the RFID devices and how they work is critical for analyzing privacy issues that surround this technology. The main components of an RFID system are a chip/tag, reader, and database. A reader scans the tag for data and sends the information to a database, which stores the data contained on the tag. The chip or the tag is usually made of silicon and it contains information about the item to which it is attached. A chip is used by retailers and manufacturers to identify consumer goods that may contain an Electronic Product Code (â€Å"EPC†). EPC chips are encrypted with a unique product code that identifies the individual product to which it is attached, and can be read using radio frequency. These codes contain the type of data that product manufacturers and retailers will use to track the authenticity and location of goods throughout the supply chain. RFID chip may also contain information other than an EPC, such as biometric data. The antenna attached to the chip is responsible for transmitting information to the reader, using radio waves. Generally, the bigger the antenna, the longer the read range. The chip and antenna together is referred to as a transponder or, more commonly, as a tag. The reader (or scanning device) also has its own antenna, which it uses to communicate with the tag. Readers vary in size, weight, and power, and may be mobile or stationary. Although anyone with access to the proper reader can scan an RFID tag, RFID systems can employ authentication and encryption to prevent unauthorized reading of data. A reader can scan a tag without physically â€Å"seeing† it. Further, RFID readers can process multiple items at one time, resulting in a
