emergencies. Radios were, and continue to be, the primary source of communication; relaying information from computing resources found within the office to officers in the field. However, the evolution of mobile technology has increased the autonomy of first-responders in the field, with nearly all emergency vehicles now equipped with on-board computers. Nonetheless, the capabilities of these devices remain limited and first-responders are still tethered to their vehicles and radios for…

Another 1970s show that was popular and was the longest-running sitcom in the history of television was The Jeffersons. The Jefferson family owned a chain of dry-cleaning businesses. From the help of their business, the African American family was able to “move on up” to a fancy uptown apartment. (Garrison- The Evolution) This show changed the stereotype that most Americans had that all African Americans were poor. The show not only proved to Americans that African Americans can be successful,…

Take the show Grey's Anatomy for example, which is an inspiring and educational show on the uprise. Medical TV shows across America have increased awareness for different medical problems and influenced a new generation of doctors. One of the major pros of…

C. August Haygood COMM 6720 9 October 2014 `black•ish: a rep•re•sen•ta•tion Primetime television is a block of time that is typically scheduled between 7:00 p.m. until 10:00 p.m. Many of the programs broadcast during this portion, provide the highest audience ratings of a day for a network. The shows can range from dramas, to comedies, to reality/game shows. This is also a premier advertisement opportunity for companies and their products. Within this time frame, there has always been a…

utilized in cellular networks but there are only three basic modes of signal communications. These are simplex, half duplex and full duplex. In simplex transmissions the signal goes in only one direction and this type is usually seen in television and radio stations. Half duplex signaling is bi-directional but each signal has to wait its turn because only one can travel at a time. Examples of half duplex are the push-to-talk Nextel phones and standard walkie-talkies. The third communication…

Communication satellites, used for relaying anything from telephone signals, radio, and television signals, have been orbiting Earth since the first in 1962. Currently, there are more than 1,100 publically and privately owned active communication satellites in orbit with more than 2,600 inactive ones causing a significant amount of space debris. Importantly, communication satellites provide our security and our entertainment. At a high altitude of nearly 36,000km from Earth, the geosynchronous…

The design for a satellite to photograph the surface of the earth requires a list of desired features, prioritized from most to least importance, and balanced against the physics of nature’s various waves. To photograph natural and man-made objects on the earth’s surface, the camera must be in the proper location, contain ample power to operate all systems, contain sufficient image resolution to capture the target area, and have the ability to transmit the digital images quickly and reliably to…

The history of Journalism is something so unique to study. Media has improved in so many ways over time. Looking back to the ways people received their news, I come to realization that there are many differences. The speed of time as well as strategies taken to express information are just a few examples. The earliest methods of transmitting news was through words written, which possibly limited its content to what people took out of the message. The accuracy of what was processed depended on…

Is the radio still one of the major devices? And what did the invention of the radio make possible for us? Radio made the communication over distance faster, it brought entertainment to the people’s houses, cars and it made live sessions possible. We have to ask ourselves what the radio waves might do to our body. Radio waves are made of two type’s, electrical and magnetic energy. (Steve Parker, “How Radio Works”) Nobody knew how it will affect the human body. They are largely unaffected by day…

bills, shopping online, checking account balances, and so much more are being done with a mobile device. Having a cell phone does make things much easier, but everything comes with a price. Studies showed that cell phones emit radiofrequency energy (radio waves), a form of non-ionizing radiation, from their antennas; tissues nearest to the antenna can absorb this energy (Ahlbom A, Green A, Kheifets L). These energies that are…
