Communication refers to the process through which people convey information. Components of communication include a sender of information, a message, and the intended receiver (Chen et al., 2011). The communicating parties must share an area of communicative commonality in order to convey a message successfully. This discussion will consider the explanation of the scientific and technical concepts related to communication, people’s perspective on communication technology, and the developments that have led to the current infrastructure of the United States.
Electromagnetic waves refer to radiation including radio waves, visible light, X-rays, and gamma rays, in which magnetic or electric fields vary simultaneously (Chen et al., 2011). The electromagnetic waves that act as communication media include radio waves, microwaves, infrared, and optical waves. Optical and radio waves are significant in telecommunication while microwaves and infrared are conveying information over short distances over the Earth’s surface (Chen et al., 2011). The sender must first convert information into digital signals through modulation before sending it by electromagnetic media such as optical or radio waves. At the receiving side, the digital signals undergo conversion through demodulation for the recipient to get the information (Chen et al., 2011).
Wireless communication technology will be useful in creating efficient way to perform duties. In today’s world, doctors spend a lot of time administration work instead of making the diagnosis. Doctors will be able to store information directly upon making diagnosis when the personal digital assistant (PDA) has a wireless connection to their desktop and, thus, there will be enough time for doctor patient meetings (Shen et al., 2011). Wireless communication allows for video conferencing, which will enhance quality education at low cost (Timothy, Tugrul, & Jisun, 2008). A teacher can transmit educative information to numerous students across the world at the same time. Examples of communication technology in the contemporary society include mobile technology, Internet, radio, just to mention a few (Chen et al., 2011). The radio and mobile phones make use of radio waves in the transmission of information, while the Internet depends on the General Packet Radio Service (GPRS).
