Firewalls and Anti-Virus Programs Essay Example for Free

Firewalls and Anti-Virus Programs Essay Electronic Computers are machines that are designed to make the jobs of humans easier. The rise of industrialization made it inevitable for humans to develop such a mechanical object which may lighten tasks that consume a lot of time and thus, need painstaking care. Humans have been successful in this undertaking, but unfortunately, as humans are susceptible to errors, so do are these machines (Copplin). Computers no matter how mechanical they are, have limitations. Sometimes these limitations are made apparent by humans unintentionally, but there are also times when humans design things that are meant to rival the advantage of their own work. As they have created useful programs, they also made not only inutile but also utterly destructive programs. They created viruses or worms that affect computers, in a way that a disease might affect a person. The solution for â€Å"computer illnesses† comes in the form of firewalls and anti-virus software. These are programs that are created to counteract the effects of viruses. They serve to both shield and prevent the entry and artillery when a breach has taken place. This shield function involves filtering of all files coming into the computer while the artillery may include quarantine activities to avoid the spread of any acquired virus (Barrios). As viruses are programs that are meant to reproduce and damage the computer system through multiplication, anti-virus programs are designed to act like healers. They are programs that actively search and destroy viruses or malicious programs in one’s computer. They scan newly downloaded files to assure that there is no entry of infection in the system. Anti-virus programs may be updated as often as the computer owner wishes. This update will enable the program to familiarize itself to developments of new viruses that are spreading or improvement of old ones thus, the security of the system is continuously adjusted and improved to better suit the need of the system (Barrios). There are many available anti-virus programs in the market. Some are installed through CD and others are downloadable without fee from the internet. Two of the most famous anti-virus programs are the Norton anti-virus program and the Mcafee anti-virus program. They were proven by numerous computer users as very effective softwares. They are also affordable and convenient as they offer regular upgrades for the programs on the internet. Like any other programs, there are also disadvantages of anti-virus programs. Anti-virus programs are reactive programs that are designed to respond to the newly developed viruses or threats. This may be considered as a benefit for an immediate cure may be devised and administered readily as response, but there are also facts that point that this nature of anti-virus programs may actually be considered a drawback. Because of this nature, these kinds of programs are prone to false positive results. Since the upgrades are automated, there is a high probability for mistakes. There are anti-virus softwares that take a while before detecting new threats on the net. The shortest time that an anti-virus program may track a threat is three days after it was released on the net. Today’s researchers are still in the process of improving this and gradually reducing it to a smaller number (Hruska) With such a loophole, computer users may resort to another security option. Other than anti-virus programs, they may also opt to install firewalls in their private or corporate networks. The anti-virus programs serve as the artillery while the firewalls are the shield that re put up in defense of the important files saved in the computer hardware. Firewalls are programs designed to protect private networks from unauthorized entry. It prevents other users to access and extract files or information without permission from a main source that is connected to the internet. Huge companies who consider not permitted extraction of information as a cause for concern may utilize firewalls to secure their files (Ranum). Some firewalls are designed to do one or two things. Some installed firewalls protect a personal or a company’s internal network from unwanted interchange from public internet. There are also some that may limit the access from the hosts of the corporate network to public services available on the internet. Still, there are other firewall setup that may support the use of private IP addresses for corporate or internal networks while at the same time share one connection to the public internet (Barbish). As according to the above-mentioned functions, there are many advantages in installing a firewall in one’s computer especially within a corporate network. However, like the anti-virus software, firewalls also have disadvantages. Since there are some firewalls that cannot function as the other does, it makes it impossible to have all the necessary security measures by installing only a firewall. It is not also probable to install more than two firewall programs in one’s computer. In addition, firewalls do not function the way anti-virus softwares do (Caruso) Given that, firewalls are known to work best with an anti-virus software. Where the firewall fails, the anti-virus software continues to work. They are mutually necessary for each other in order to have a tight security for one’s personal computer. Anything that passes the firewall may easily be traced by the anti-virus program the moment it does internal scanning of files in the hard drive. While anti-virus programs are designed to protect a single unit of hard drive, the firewall works well as a barrier from malicious programs and hackers for networked computers (Ranum n,p). It also acts as a screen that keeps the private network safe from malicious users in the internet. Some users get confused on what should be applied to their computers. While it is already quite depressing for single unit users, large corporations are boggled by this dilemma. If in any case the threat gets past both the anti-virus program and the firewall, all information that is classified goes out to the public. This is why some large corporations would rather have no internet connection than risk their security (Ranum). Researchers suggested that since one of the two security programs cannot function as the other, it may be effective to use them together. First is to install a firewall that will keep all threats out. Second is to put in an effective anti-virus program which can trace new viruses on the net the fastest among all other anti-virus software. Then install another firewall program for better measures in case both initial programs were breached. This way, the trespassing users in the public internet may be kept out as well as the malicious programs that may destroy the whole system of the computer (Cheswick 90). It may then be concluded that the desire of man to make work lighter have lead to the advent of computers and other technological advancements. However, due to the unquenched desire to improve things, man has also created things that can damage or destroy what has been created. This way man can once again build something that may respond to the destruction that has been invented. In the case of computers, the things that destroy are the viruses designed by some programmers, while the things that respond to the damages are the anti-virus programs and firewalls. The firewall protects a personal or corporate network from any breach by unauthorized person who has internet access. It protects classified information from spreading without permission and also prevents spread of malicious programs that may enter through the public network. On the other hand, the anti-virus acts as support in cases where the threat has already entered the system. The other is the guard while the other is the cleaner. These two computer innovations compliment each other in keeping the files and the entire personal or corporate computer system safe and well guarded from any kind of malicious threats.

The Wife of Bath :: essays research papers

  Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Sovereignty† or believing that a happy match is one in which the wife has control is the backbone to the story of the wife of bath. When the wife of bath finishes telling her story there are no comments from the other pilgrims. The thoughts of both the parson and the knight will be depicted as I imagine them to be in response to her tale. I can see the parson looking to his left, explaining his displeasures to the monk. They talk of her story with the parson sharing his ideals, and the monk just smiling back, looking him in the eye and chuckling. The parson who attempts to live his life as an ideal for others was appalled to learn of the wife of baths four husbands and as she told how she gained control over the fifth one by faking her death, the parson lost all religious respect for her. The parson hates to think, and totally disagrees with her theory that being over powered by a woman would make any marriage happy, personally he would be unhappy, and would never be with a woman who didn’t fallow the word of god.. The parson would have wanted the knight who raped the woman instead of becoming the hero of tale, to be punished in order to be fair to the others who have been punished before him. The knight whose very code of honor emphasizes chivalry, truth and honor would be totally disgusted to hear that in the tale by the wife of bath that a knight raped women. He would be angry at the wife for choosing a knight when any type of person could be chosen to represent the male in her tale. This talk of a woman dominated house hold would not be something that would be a ideal to the manly knight whose dignity and status allow him to stand apart from the rest. The wife of baths history as a person would make him think twice about anything she had to say, as she has little honor but what she lacks in honor she makes up with in pride. The tale ends with a knights ending they live happily ever after. The knight would have no problem with most of the story although be aggravated by pessimistic rhetoric of his fellow knights. Question 3   Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã‚  Ã¢â‚¬Å"Love of money is the root of all evil† is a lesson that we could all learn in addition to the theme of the pardoner’s tale.

Effects of Emotions on Driving Essay

There are reported cases of vehicular accidents every year in the United States. Even though drivers are aware that drinking and using cellular phones while driving are dangerous, they overlook other factors that might contribute to accidents such as physical condition and emotion. Emotions, along with personality types, video games and gender differences, determine driving behavior. Emotions can be a positive force in determining driving behavior. For instance, a person can be motivated to drive safely by his love for his family. Moreover, if he fears any legal consequences or accidents, it might restrict him from reckless driving. On the other hand, if a person has emotional problems, this can possibly lead to collision. Some may think that emotions may have little effect on one’s driving. But according to researches, any kind of emotion has negative impacts on driving, which can cause impairments that the driver is not fully aware of. A person who is frightened, depressed, upset or excited while driving may be in the same danger as someone who is engaged in a phone call or is drunk (DMV, 2008). There are also cases when a person has to drive after attending to an emergency or after learning of a loved one’s sickness or death. To avoid accidents, it is advisable that the driver pause a while to get his bearings straight before getting behind the wheel. Research about causes of vehicular accidents showed that those who are experiencing negative and even positive emotions were at a distraction level more serious than those who were engaged in a phone call. These emotions can affect even excellent drivers in many ways. First is that they might experience â€Å"dimmed or impaired observation and reaction times† (DMV, 2008). Second, drivers might not see debris in the road or might not recognize situations such as slowing of traffic, which can result to hitting other cars in the way. Third, drivers might not recognize what is happening around them (Connolly, 2007). For instance, they might not recognize that a car ahead is turning around or is about to cross. Fourth, emotions might cause drivers to make risky changes such as abrupt change of lanes. Fifth, they might feel as if they were detached from their surroundings (DMV, 2008). There might be some cases wherein a person is involved in a road rage. Road rage has become too common these days. It is responsible for many cases of bodily injuries and accidents on the road. These accidents can be attributed to the fact that some drivers overreact and personalize driving situations. Researches about road rage showed that more than half of all the drivers in America can express road rage themselves, or they can be a victim of another driver’s road rage. Moreover, the U. S. Highway Safety Office declares that the many cases of accidents on the road are connected to road rage or aggressive driving, as such, road rage is now the primary cause of death (DMV, 2008). The personality type of a person can also determine his driving behavior. Personality type is categorized into Type A and Type B. Type A is those that are impatient, aggressive and hostile while Type B is those calm individuals (Sedona. com, 2007). One of the traits common in the abusive personality or Type A individuals is recklessness in driving. Drivers categorized as Type A are always in need of power and control. This might be an explanation for engaging in road rage situations. Emotions’ effects on driving can be further explained by what is going on in the parts of the brain involved. Emotions have effects on the part of the brain responsible for reason, thought and judgment. These brain parts mature when a person reaches 25 years of age. Thus, drivers below 25 years old, especially teenagers, are at risk of accidents (Davis, 2005). The parts of the brain related to emotion and decision-making of the teens are still developing. As their brain develops, teens are susceptible to risky behavior such as driving too fast. Brain immaturity is responsible for the high number of teen crash rate today. Recent brain researches of the National Institute of Health (NIH) have come out and shown that young drivers are at risk of accidents because the â€Å"executive branch† of the teen’s brain that is largely responsible for weighing risks, making judgments and controlling impulsive behavior is not yet developed. Results have shown that a â€Å"16-year-old’s brain is far less developed† (Davis, 2005) than those teens who are a bit older. This explains why there are more 16-year-old drivers who are at a higher risk of crashing than those older teens. In fact, a recorded number of 937 drivers who are 16 years of age were involved in fatal crashes in 2003. Almost half of those drivers and 352 of their passengers were killed. Thus, young teenagers need supervision because they are too young to drive. Another factor that psychologists and doctors looked into to explain the many cases of teen crashes is the video games. Video games on racing feature realistic driving environments wherein players must race through city and traffic (Wood, 2007). Several studies were conducted to determine the relationship between video games and driving. One such study was conducted by Douglas Gentile and Craig Anderson, both psychologists. Video games are interactive and engaging. Plus, violent behavior in video games is rewarded. Thus, teens and even adults tend to repeat these behaviors as they play. Gentile and Anderson indicated that for these reasons, violent video games may have stronger effects on aggression. The results have also shown that video game is directly related to having aggressive thoughts and behavior (cited in American Psychological Association, 2004). Another study by German researchers has also shown that video games affect those who play them. The researchers stated that the video games exhibit â€Å"competitive and reckless driving, speeding and crashing into cars or pedestrians, or performing risky stunts† (cited in Wood, 2007). This means that the actions in video games can result to accidents or crashes in a realistic racing environment. The researchers chose 198 men and women to participate in the study. Results showed that those who play more often were likely to engage in risky and aggressive driving and getting into car accidents while those who played less often were more cautious in driving (Wood, 2007). Studies were done to determine the difference between male and female when it comes to driving. Men are more aggressive than women, as is explained by testosterone, the male sex hormone responsible for aggressiveness in men. Most people want to know if men tend to be aggressive compared to women when driving, as such, a study showed a situation wherein a male driver became upset when another driver cut in front of him. He followed the car until he found out that the driver was a female. He was shocked because the female driver drove violently, when in the society women are not depicted to drive aggressively. If the other driver was not female, would the driver’s behavior of following the car be justified? Just from observation alone, we see how men and women differ in emotional behavior when driving. Men will likely criticize another driver, making sure that the other driver can hear him. Women, on the other hand, will likely criticize other drivers to themselves because they fear retaliation. There are also instances when emotional behaviors get in the way of safe driving. For instance, a girl asked her boyfriend to drive her home, but the boyfriend got upset. At 60mph, he sped around corners where the speed limit was 25mph. The boyfriend’s want for being in control forced his girlfriend to comply with his emotions. Anger sometimes gets the best of drivers. It results to behavior that is destructive for both the driver and the passenger (Lucey, n. d. ). Emotions affect driving. When a person is elated, frightened, worried or depressed, he or she might not be able to perform well in driving. Aside from emotions, other factors that can affect driving are personality types, video game influences and gender differences. References American Psychological Association.(2004, June 8).

International Business Communications Essay - 1332 Words

In the past five decades, changes and advancements in economic relationships, political systems and technological options began to break down state boundaries. Business transformed from one country activity to part of an interdependent international network. As Damen writes â€Å"One cannot live very long and remain totally monocultural in the modern world† (1990, 56). However, international business communications do not effective every time.

There are some solutions that lead to success in communicating business with people who have backgrounds which unlike each other. The most important aspect is to learn another culture. Molly and Daniel may not be conducting a comprehensive training program about the cross-cultural awareness because they do not have plenty of time. Still, they can give those businesspersons who belong to multinational companies a presentation about intercultural awareness or a consultation to enhance people’s awareness of cross-cultural. In addition, language and language behaviour, especially non-verbal communication has a very significant role in the intercultural communication, such as clothing, eye-contact, proximity and touching. Molly and Daniel should pay attention to this aspect. Mere knowledge about the language will not be important to sort out the differences and misunderstandings in communication. However, the non-verbal communication is very essential in the process of cross-cultur al communication. Lack of experience in expressing language behaviour properly reduces the self confidence among the people and develops a poor interpersonal relationship. To sum up, the best solution for Molly and Daniel is that introduce cross-cultural awareness to those businesspersons.
