Networking Essays (1661 words) - Server, Server Hardware

Networking For my independent study, I have created a network in my house. A network by definition are more than one computer that are linked together electronically via a protocol (common language) so the computers can communicate and share resources. This network improves the day-to-day life by adding value and usefulness to the computers. The processes and ideas that I have learned thru this experience can be applied directly into todays rich electronic business environment. Identifying the needs of the user is the first step for building a well-designed Network. A professional installation was needed to maintain the aesthetics of the rental house. Most of the wires are run in the attic and then down plastic conduit attached to the wall. The conduit is run all the way to the wall boxes where the Ethernet ports are located. Every wire is clearly labeled and included in an easy to read schematic of the house. This way future tenants will have the ability to utilize the network. Next, every room needed to have access to the network. In order to minimize the overall use of wires, hubs were placed in strategic locations. An 8-port 10/100-megabit auto-sensing hub is located in the computer room and a 5 port 10-megabit in the sound room. There, needed to be docking stations, so laptop users or visiting computers could easily plug into the network and utilize the pre-existing monitor, keyboard, and mouse. These are the basic needs that have been put into the des ign of the network. Each computer setup is unique with certain strengths and weaknesses. The network takes advantage of the strengths of each individual computer and makes them available to all users. A network essentially expands the capabilities of each computer by increasing functionality thru resource sharing. In the house, there are a total of four computers and two laptops. Processing speed and an abundance of ram is not essential for a server with such low traffic. Thus the most antiquated computer was elected for this function. Between all the computers, we have several extra pieces of hardware such as a zip drive, CDRW, DVD ROM, scanner, and multiple printers. Each piece of hardware is dispersed between the computers. There were several immediate efficiencies that occurred when the network went operational. The zip drive is located on the server while the CDRW is located on one of the individual workstations. Previously, if the need arose to burn some information stored on the zip disk to a CD, the individual computers were practically worthless for this task. However, with the network, one can map a network drive on the computer with the CDRW to the zip drive on the server. This allows information to be efficiently transferred from the zip drive to a CD. In addition, the server also has a scanner attached to it. The problem is that the server is too slow to handle sophisticated photo editing software. Now an image can be scanned on to the server and then a faster computer can be used to edit it. There are 3 different printers, each varies in quality, speed, and maintenance costs. The most expensive one is reserved for only making color photos, and the other two are used for everyday printing, one of which is much faster and has more reliable paper feeding. A user can easily choose a printer depending on their needs. This network takes full advantage of each computer through resource sharing which ads tremendous value for its users. In Business it is important in any network to be able to restrict access to individuals private files or directories. Security would demand that not all users would be allowed access to highly confidential information. There is other information that would be made available to other users on a read only basis. The same is true of the users in my network. Microsoft developed NT to be very secure. Most of this security is devoted to protecting network resources and the filing system (NTFS). The administrator decides who gets access to which resources by setting up users and user groups. Each person is asked to choose a user name and password. Then the administrator identifies the needs and privileges of each individual user.

buy custom Global Warming as a Fact or Fiction essay Global warming refers to the rising of the earths atmospheric temperature usually caused by human or manmade activities and other natural causes such as volcanic activity. The highest percentage of global warming has been caused by human activities, which include; charcoal burning, coal mining, ranching and use of fertilizers when farming, which releases green house gases (Budzianowski, 2011). Such gases may include carbon dioxide, methane and nitrous oxide into the atmosphere. Deforestation also leads to increased rise in temperatures since the cut down trees would have trap the heat emanating from these activities. Effects of Global warming Low food production The rise in temperature will cause changes in the rainfall patterns, which will lead to high rainfall or dry seasons. During dry seasons, there will be little or no water for irrigation while during heavy rains, large hectares of land will be flooded according to Hutchings Gibson (2010). As a result, food production will be low and thus, low food supply. Rise in food prices Low food supply and high demand for food will lead to hiking of food prices because people will be competing for the little that the suppliers are able to bring to the market. Increased Diseases Global warming will also lead to increased diseases brought about by malnutrition due to low food production, heat waves, increased insects e.g. anopheles mosquitoes lading to more diseases such as malaria. Increased deaths More people will lose their lives because of ailments and diseases, drowning in case of heavy rains, hunger due to drought and famine that leads to low food production. Animals will also not have food to eat and will therefore die from hunger and malnutrition. Increased government spending and loss of government revenues Floods will demand from the government money to be relocated to areas where there are no heavy rains. Government will also spend more during drought and famine in feeding those affected. Global warming will lead to melting of ice caps and wildfires will most definitely destroy the tourist attraction sites such as mountains. There will be fewer tourists visiting those sites and this will reduce the governments revenue. Loss of property Properties worth millions and billions of money will be damaged due to heavy rains. Cost to the employers will therefore increase and reduce profits or revenues (Ball, 2007). These costs will be in forms of increased repair and maintenance costs, cost of buying materials for rebuilding again, cost of supervision and cost of paying the constructors. Global warming can be reduced through the following ways Recycle and reuse Papers should be reused and recycled since this will combat deforestation, which causes global warming. Strict measures, rules and regulations The government should come up with laws, rules and regulations that will help reduce deforestation and charcoal burning according to Boretti Watson (2011). Those who defy such laws should be imprisoned or pay some charges as expressed in the Acts of parliament with regard to such matters. Campaigns and Education The government and other stakeholders should be actively be involved in creating awareness among people about what is global warming, their causes and effects. The government can also incorporate a subject about global warming in the education system (Dash Wu, 2011). This way, people will become more informed and global warming will be reduced considerably. Energy conservation Alternative products which consume less energy should be used e.g. a compact fluorescent bulb can replace a usual light bulb, insulators can also be used, people should walk more as opposed to driving wherever possible (Ray, 2010). Conclusion In a nutshell, global warming is a subject of concern and from the above discussion it is indeed true that global warming is manmade. Its causes are something that can be reduced if not eliminated (Connor, 2005). If so, their effects, therefore, can be reduced a great deal and thus lives and properties can be saved. It is for that reason that everyone should take upon themselves in ensuring that global warming becomes an issue of the past. Buy custom Global Warming as a Fact or Fiction essay

Racism in the United States in the Context of Freedom of Expression Essay

Racism in the United States in the Context of Freedom of Expression and Freedom of Association - Essay Example Some of these people have made racist associations strong and thereby passing extremist messages (Bleich 81). These people act the way they do, in some cases, a bid to overcome dilemmas just like Allen presents in Where I come from Is Like This, â€Å"Most Indian women I know are in the same bicultural bind†¦ We resolve the dilemma in various ways†¦ We act in these destructive ways because we suffer from the societal conflicts caused by having to identify with two hopelessly opposed cultural definitions of women† (Allen 45). When individuals are denied the chance of organizing themselves into groups, they will have a difficult time presenting their views or opinions in a democratic society. Majority of the people in the United States and other nations such as Western Europe do not value freedom of association. This is because they join private clubs, bowling leagues, and political parties without any reason. They have become accustomed to the associations such that l imiting or denying any group from organizing to further their interests is considered to be limiting their desires to promote a vibrant political sphere and civil society (Bleich 85). This is evident in Paula Gunn Allen’s article Where I Come From Is Like This. Allen states that members of her community resolve issues and dilemmas in many ways; partying all the time, drinking in excess, and engaging in violent exchanges (Adams 203). This indicates the way the people have become accustomed to associations that link them on a common agenda. Countries measure freedom of association against racism in a number of ways. Racists’ autonomy in the United States has been aggressively protected. Groups or associations such as the Ku Klux Klan, racist skinhead crew, anti-Semitic black separatist groups, and small neo-Nazi parties function legally and openly in the United States. Southern Poverty Law Center in Alabama has tracked these groups, and associations for years and it stat es that there were 900 of them in 2008, indicating an increase in 200 active hate groups since 2000. The modern interpretation of Constitution in the United States has made the freedom of association a fundamental right thus making it nearly difficult to outlaw a group on the basis of its racist characteristics (Bleich 86). Protection of the racist groups in the United States can be equated to Harlem in the James Baldwin’s Sonny’s Blues. The Harlem community is faced with numerous problems such as poverty, frustration, and drugs. However, the community members come together to protect and watch over one another. The adults use most of their time in the afternoon sharing stories and offering their children a sense of protection and warmth. The â€Å"music becomes the means for the brother’s reconciliation and functions as an â€Å"art of communion† which extends the meaning of each individual’s ‘blues’ (i.e., sorrow) to become a metaph or for the African American community in general† (Recker 30). The brothers and the community watch and protect one another despite the problems facing them. Outlawing such an association can be very difficult because of the protection developed among them. Thus, it is the mandate of the United States to show brotherly love to the racist associations as indicated in
