Radio Waves :: physics radio wave

Radiowaves are the oscillations of magnetic waves by varying the modulation to generate different signals which can be converted into information such as sound, video, or digital communication. As these waves pass through a conductor, an alternating current is generated and this can be converted into usable information. As one could see from the picture above, radio waves are the the electromagnetic waves with wave lengthes between 1mm and 10 Mm. This converts to a frequency range of 300Ghz to 30Hz, respectively. Nearly everyone uses radio waves in some form day after day. The technologies that depend on them is vast and ever-growing. These technologies range from cordless phones and garage door openers to radar and microwave ovens. Radio is not a dead technology either. It is constantly having research devoted to it and new technologies and innovations are coming about from this research. The trend towards wireless internet and more versatile cellular phones are just some examples. Ironically, the fundamentals of radio waves is relatively simple (atleast when compared to the vast array of technologies that now implement it). Cordless phones use radio waves to allow individuals to walk around freely in their home without the need to be bound by a cord while talking over their land-based phone line. Cell phones are a miracle to modern day living. Unlike previous eras where communication was done strictly across a hard-wired telephone line, cell phones now give the freedom to those that can afford them a radio-based uplink to the rest of the world. Not only are they for voice communication, but they also allow for transmission of virtually any kind of digital data. Microwave ovens are another great invention from the 20th century. They use radio waves in a specific frequency range in which water, fat, and sugar molecules happen to absorb and convert directly into heat.

Identify potential weaknesses from either the Aircraft Solutions or Quality Web Design Company Essay

In this phase you will choose either Aircraft Solutions or Quality Web Design as the company you will work with. The scenarios are in Doc Sharing in the Course Project select area. You will then identify potential security weaknesses. Security weaknesses – You must choose two from the following three areas (hardware, software, and policy – excluding password policies) and identify an item that requires improved security. To define the asset or policy with sufficient detail to justify your assessment, your assessment must include: * the vulnerability associated with the asset or policy * the possible threats against the asset or policy * the likelihood that the threat will occur (risk) * the consequences to mission critical business processes should the threat occur * how the organization’s competitive edge will be affected should the threat occur To clarify an item that requires improved security, you must identify one of these items: * one hardware and one software weakness * one hardware and one policy weakness * one software and one policy weakness Other required elements include: * Cover sheet * APA-style * In-text citations and Reference section * Minimum length 3 pages, maximum length 5 pages (not counting cover sheet, diagram(s), references). Do not exceed the maximum length. Phase II: the Course Project (comprised of Phase I and II) – Recommend solutions to the potential weaknesses from either the Aircraft Solutions or Quality Web Design Company In this phase of the project you will include Part I (presumably improved as needed based upon Week 3 feedback) and then you will recommend solutions for the security weaknesses you identified in the Phase I. Definition of the solution – Hardware solutions must include vendor, major specifications with an emphasis on the security features, and location of placement with diagram. Software solutions must include vendor and major specifications, with an emphasis on security features. Policy solutions must include the complete portion of the policy that addresses the weakness identified. Any outsourced solution must include the above details and the critical elements of the service level agreement. Justification – You must address the efficacy of the solution in terms of the identified threats and vulnerabilities; the cost of the solution, including its purchase (if applicable); and its implementation, including training and maintenance. Impact on business processes – You must discuss any potential positive or negative effects of the solution on business processes and discuss the need for a trade-off between security and business requirements using quantitative rather than simply qualitative statements. Other required elements include: * Cover sheet * APA-style * In-text citations and Reference section * 5 reference minimum * Minimum length of solutions: 6 pages, maximum length 10 pages (not counting cover sheet, diagram(s), references). Do not exceed the maximum length P.S. Phase 1 is done and attached. Just need help with phase 2.

The Legal Drinking Age Should Be Lowered - 1170 Words

For a majority of the 20th century, the United States drinking age has been a big issue. After prohibition had concluded in 1933, twenty- one was the new legal drinking age. Meanwhile, during the Vietnam War, eighteen became the new legal drinking age. Finally in 1984, Congress passed the National Minimum Drinking Age Act (MLDA). Since then, twenty-one years old has been the legal age to drink in the United States. There are several ways alcohol has been a reason for death such as, alcohol poisoning or drunk driving. Americans death rate has increased in the past few years for alcohol poisoning in the adolescence stage. Just because the majority of teens consume alcohol underage does not mean the legal drinking age should be lowered. Although the legal drinking age in the U.S. should stay at twenty-one years old due to small reasons such as, drinking under the influence or alcohol poisoning, the MLDA has helped teens with larger reasons such as the avoidance of tobacco, cannabinoids, opioids or club drugs. Another extensive reason why the legal drinking age should not be lowered is because of the unsafe surroundings teens would be allowed into such as bars and nightclubs.
