Guided media are more commonly known as wired media, or those media in which electrical or optical signals are transmitted through a cables or wires. Unguided media are more commonly known as wireless media, in which electromagnetic signals are sent through space with no direction. Both types of media can be used for long-distance and short-distance communication.Know More
In guided media, electrical signals are confined within the cable or wire which transmits them. Typical forms of guided media include copper co-axial cables, fiber-optic cables and twisted-pair copper cables, which can be shielded or unshielded. Guided media are also sometimes known as bounded media.
Different types of unguided, or wireless, communication are classified based on the frequency spectrum used for communication, the distance between the end stations and the type of encoding used for the communication. Unguided communication allows electromagnetic signals to travel between antennas, some of which are on satellites. Antennas can provide point-to-point communication or can send their signals in all directions.
Transmission of digital data through either guided or unguided communication involves the coding of the data at the sender's end, the modulation of the carrier signal, the demodulation of the signal on the receiving end and the decoding of the binary signal.Learn more about Magazines & Newspapers

Magazines, newspapers, flyers, newsletters, scholarly journals and other materials that are physically printed on paper are examples of print media. Whereas print media was once much more prevalent, the advent of e-books, digital publishing tools and applications have caused many groups that typically created print media to begin publishing through digital channels.Full Answer >
According to the National Communication Association, one example of cultural stereotyping by the media is the portrayal of African American women as a "mammy" who represents anger, largeness and motherhood.

Newspapers provide an outlet for large teams of reporters to report media that may be overlooked by major television or online news stations. Newspaper reporters learn to cover various "beats" locally, allowing them to develop relevant news stories. Television stations often lack adequate staff to do this.Full Answer >
