Extended Definition †Firewall Essay Example for Free

Extended Definition – Firewall Essay Firewall – (1) A computer program or hardware device used to provide additional security on networks by blocking access from the public network to certain services in the private network. (2) It is an integrated collection of security measures designed to prevent unauthorized electronic access to a networked computer system. It is also a device or set of devices configured to permit, deny, encrypt, decrypt, or proxy all computer traffic between different security domains based upon a set of rules and other criteria. Etymology Firewall is consisting of two words â€Å"fire† and â€Å"wall†. Fire can be traced from the Old English word fyr a Germanic language which means â€Å"fire, torch†. In Old Czech language pyr means â€Å"hot ashes†. Moreover, wall is can be traced from the Old English word weall which means rampart (natural as well as man-made) and defensive fortification around a city, side of a building, interior partition, which apparently a borrowing from Classic Latin vallum which means wall, rampart, row or line of stakes†. However, the term firewall, as we used here, is a recently coined term for network security and technology. History and Background The term firewall originally meant a wall to confine a fire or potential fire within a building, c. f. firewall (construction). It was also used later on as a referral to similar structures, like metal sheet that separates the engine compartment of a vehicle or aircraft from the passenger compartment. Firewall technology emerged in the late 1980s when during that time Internet was a fairly new technology in terms of its global use and connectivity. The forerunners to firewalls for network security were the routers used to separate networks from one another in the mid to late 1980s. Firewalls are important for the following reasons: it can block unauthorized users to access your network; it can protect the network from attacks using the e-mail system; it can prevent vandals from logging into the machines on your network; and it can serve as a tracer for those who attempted to use your network’s data.

Automobile Air Pollution :: essays research papers

Automobile Air Pollution Efforts to improve the standard of living for humans, through the control of nature and the development of new products have also resulted in the pollution of the environment. Much of the world's air, water, and land is now partially poisoned by pollution. Some places have become uninhabitable. This pollution exposes people all around the globe to new risks from disease. Many species of plants and animals have become endangered or are now extinct. The air pollution comes from lots of sources but the paper will be about air pollution cause by automobiles. As a result of tremendous amount of air pollution, primarily for automobile governments have passed laws to limit or reverse the threat of environmental pollution.   Ã‚  Ã‚  Ã‚  Ã‚  There are lots of sources other than the automobile for air pollution. Nature itself is one of the causes. Sometime nature causes the air pollution by activities like a forest fire, volcanic, hurricane. These are temporary dislocations that nature balances and accommodates to modern economic development, however, sometimes disrupts nature's delicate balance. The other source is from factories. Factories are release smokes and chemical in the air. In many places smoke from factories and cars combines with naturally occurring fog to form smog and create a midday sky. It had happened in London, â€Å"London, England, has been subjected to the danger of smog, long recognized as a potential cause of death, especially for elderly persons and those with severe respiratory ailments† (pollution).   Ã‚  Ã‚  Ã‚  Ã‚  Transportation by car though, is the major source of air pollution. Early in the century human invented, internal combustion engine, engine that use fuel as gasoline or diesel. Those engines were used to manufacture an automobile for fast travel from one place to another. Because they were not much in use, those few cars were not enough to threat the environment. Those engines were not fast enough so mastermind humans invented bigger and faster engines and those take more fuel. When these engines burn fuels they introduce smoke and other, less visible, by products. Once they are released into the air, the products of incomplete combustion, particulate matter (soot, ash, and other solids), unburned hydrocarbons, carbon monoxide, sulfur dioxide, various nitrogen oxides, ozone, and lead, undergo a series of chemical reactions in the presence of sunlight. The result is the dense haze characteristic of smog. â€Å"Smog may appear brownish in color when it contains hig h concentrations of nitrogen dioxide, or it may look blue-gray when it contains large amounts of ozone† (Danger).

Are Grades and Effective Means of Motivation? Essay

Believing: Grades are often seen to be one of, if not the most effective method of motivating a student to work to their fullest potential. For example, a student who receives an A-grade is going to be encouraged by the grade, as they see it to be an affirmation of their academic efforts. An A-student views their grade with pride, and will work very hard to maintain said grade, once achieved. An example of this is as follows. John recently received an A on his Math test. He then goes home with a sense of pride, bragging about it to all of his friends. John now realizes that he must keep up the good work and continue to work hard for school, in order to continue to feel as good as he does today. Conversely, a failing student will regard his/her grades with shame, and will be more motivated to raise their grade from the gutter as a result. An example of this is as follows. John receives an F for failing to complete an assignment on time. As a reaction to this, John decides that he will turn his life around completely and alter his studying habits so that he turns in his assignments on time in the future. In conclusion, grades are by all means the most effective way of motivating a student to excel. Doubting: Grades are the least effective way of motivating a student. This can be said with such certainty due to the very nature of grades themselves. They serve to rank students against each other. Personally, when I feel as though somebody is putting me up against a friend, I feel much less willing to work harder for the class than if they were to simply tell me what I needed to change in order to excel. The Whitehall Study, performed in England 1967, has shown us with certainty that humans placed in a competitive hierarchical situation over prolonged periods of time will increase their chances of gaining cardiovascular disease by 40%. This shows us that students placed under similar conditions (as they are with the grade system) are not only less motivated to work, but are also at risk of dying. Another important factor to consider when discussing high-school students and their academic achievements is that many of us are apathetic. This means that when we see a grade, we simply just don’t care about it and it doesn’t serve to motivate us one way or the other. This leads me to conclude that grades, when seriously considered by the student, are not only the least effective way of motivating students to do their best work, but are also a serious health concern. Reflection: This writing activity was unlike anything I had seen before. It challenged me to write from two entirely different perspectives, which is something very new to me. The main difficulty I faced with this assignment was the assignment itself. While it may seem redundant to say so, the assignment asked us to write about something from two polarized perspectives, and that was what challenged me the most. I found it easy enough to write the doubting response, as it is what I can most easily associate with. When it came to writing the believing response, I felt as though I was stuck. I stared blankly at my page for several minutes until I finally decided to ask an A-student what their perspective on the matter was. Doing so helped me greatly, as it broadened my mind and aided me in writing about something from an entirely foreign perspective. After completing this assignment I can honestly say that I am a more well-rounded person, as I find it easier to relate to what others are saying, even if it goes against every fiber of my existence. Believing and doubting helps me wallow in complexity by reminding me not to forget that there is a flip-side to what I am arguing at any given time, and I’ve caught myself thinking about a few of my foundational beliefs and how they can be contradicted by somebody with a different outlook on life. In conclusion, I believe that this assignment has helped me to understand that there are several other points of view to consider.
