The security of networking - Research Paper Example The article covers the basics of protected networking systems, including firewalls, network topology, and safe protocols. It is essential that firms make a substantial investment in network security in order to safeguard its exclusive information from hackers, as well as other delinquents. I will address contemporary approaches towards the network security, the upsurge in recent criminal activity. The Internet is a principal platform of the contemporary business world. One may find it difficult to stay modern on the latest global events without the efficient use of the Internet, navigate it, and appreciate it. The internet is the globe’s single greatest key source of linked networks, computers, and user links (Canavan 2001). The Internet has developed at a rate that significantly exceeds any preceding trend or development relative to contemporary information technology. There is no entity that can declare ownership of it, however the users can benefit from the capacity to access information, individuals and other resources from the entire globe and have it taken to a device such as a laptop, cell phone, tablet or other numerous devices. Establishments began to study the use of the internet and what followed was the delivery of e-commerce. With e-commerce now severely competing with the practice of the brick and mortar capacity, clients are quite comfortable with the co nvenience of shopping, finance, and otherwise flourishing fully in a virtual world (Cole et al. 2005). Commerce has also transformed to the paperless system of undertaking business and can significantly increase the efficiency. With the evolution of business and returns also came the occasion for unlawful activity. Hackers began to exploit on consumers and traders alike by committing virtual larceny. It started with bank accounts, credit cards, and social security figures but has

Orientation Training Essay Example for Free

Orientation Training Essay Blanchard Thacker (2010) describe how orientation can be described as the type of activities that an individuals or organization may seem most interested in and can give most attention. Orientation training can be described as training designed for newly hired employees to allow them to understanding the organizations operations. Also, orientation training give new employee’s opportunities to learn polices and procedures for making decision and activities of various units are coordinated. Orientation training can being with the socialization process with new employees and help the employee learn information about the organization and the values of the organization (Blanchard Thacker, 2010). Orientations can be short or have longer approach dew to the kind of organizations the employees will be working for. The value of orientation training can with the how the learning theory prospective can be based on previous learning. New information can be interpret and understand in the context that is already know. Blanchard Thacker (2010) show how successful organization can recognize the need for providing new employees with orientation training. They also view how new employees can use the organization and the first entry into the organization and whit will coming next tin the upcoming days in the organizations. The first view of the organization can be a lasting one and can important for organization to have good imaged an impression to chance the effectiveness the organization and new employees (Blanchard Thacker, 2010). Another value of orientation training can be how employees who attend orientation training can be flexible to accepting the organizations goals and values. Orientations training can be effective with the use of the guidance that is provided to employees regarding manageme nt expectations. Also orientations can be effective in reducing anxiety, reducing role ambiguity. In addition reducing turnover, improving job performance, providing high levels of commitment and can show the effective and efficient of the organizations (Blanchard Thacker, 2010). In conclusion, orientation training is designed for new employees to allow them to understanding the organizations operations. Orientation training gives new employee’s opportunities to learn polices and procedures for making decision in the new organizations. Orientations training can be effective with the use of the guidance that it helps to provide to new employees regarding management expectations. References: Blanchard, N. P., Thacker, J. (2010).

Networks Project Proposal Introduction

Networks Project Proposal Introduction Networks Project ProposalIntroduction: The home network has potential. It adds growth and knowledge. The home network is important to use and access internet connection easily in home wireless network. This network also provide many other benefits as well like as, sharing a file between your computers in your home network, sharing a media file, sharing a folders between your computers in your home wireless network.iStock This wireless network does not cost much and it has many benefits to provide to connect wireless and non wireless devices across the network. The current network is connected via cables so its wired network. A cable goes from study room to lounge and from bed room to main hall. Its not feasible to connect many devices together in home via cable network because its require cabling through out the home and many times just because of loose cabling you have to connection loss. To overcome this hurdles in home network and to connect additional devices easily to home network wireless networking is very beneficial, so I am approaching to upgrade this wired network to wireless network. So the vast benefit of wireless networking like as I can share my files and folders more easily with my laptop and desktop computers. I can access my pictures from desktop computer to mobile device via wireless home networking. To share a printer in your home network wireless networking is more feasible option to choose because, in wireless network we dont need to run a long cable from router to printer. We can adjust the printer anywhere in home and still it will be connected to your computer via wireless connection. Network up gradation provide the benefit of using more wireless clients easily. Rationale: Connecting computers together (or computer devices) has been a main concern since the beginning of the information age. In the beginning of the computer revolution computing relied heavily upon telecommunication technologies for sharing computing resources, mostly due to the cost and size of those resources. For years, computer networks were nothing more than dumb terminals connected to a supercomputer (mainframe) in another location. This was the beginning of the computer network as we know it today. This web curriculum is designed to assist students in their understanding of computer networks and to help them gain the necessary knowledge that will afford them the skills and abilities of designing and implementing their own personal computer network. Project Goals: Next-generation home networking environments will contain a variety of Internet-ready devices or embedded systems, which will result in increased complexity for the end user. New methods are therefore required to build autonomic networking infrastructures that enable auto-configuration and self-management of the networked elements. In future Internet-based home environments a variety of devices such as PCs, smart phones, networked appliances and embedded systems will be organized into infrastructures and will act together to form a new type of service provisioning platform. Todays typical home environments often contain a few of these Internet-ready devices; in the future there will be even more, including embedded systems like sensors and actuators that are also accessible via Internet technology (e.g. TCP/IP, HTTP, Web services etc). While on the one hand this gives users the freedom to access a rich variety of devices in the vicinity of their homes, on the other it increases the depth of knowledge required to understand what is happening in such a complex networking environment. Novel methods for autonomous networking as well as self-configuration, self-management, self-organization, self-protection and self-healing (self-x) of the networking elements can take responsibility for observing and controlling the home network without directly involving end users. Technology will revolutionize the tools that are used in the home of the near future. Embedded computing, sensing and actuation technologies-coupled with new infrastructure in the built environment itself-will combine to enable new opportunities to support the work of the home. The wireless home networking goal is to successfully connect wireless devices such as laptops, desktop computers, VoIP phone, wireless printer, and network storage drive and wifi cell phone. The other goal is to configure the wireless devices so they can share network folders and print wirelessly in home network and to successfully achieve that we need to install wireless router and cable modem in home wireless network. Resources: Cost: The cost to build network is illustrate bellow, Linksys wireless router Cable modem Wireless printer Virtual Lan Network storage drive (Netgear) Switch Router The cost for internet connection which is provided by ISP is not included in the proposed network cost. The devices which are used in home wireless network are under warranty by the manufacturer for 3years and the technical support is also provided. Research: Advantages Disadvantages of wireless network: Wireless network have advantages and disadvantages when compared with wired LANs. A WLAN will make it simple to add or move workstations and to install access points to provide connectivity in areas where it is difficult to lay cable. Temporary or semi permanent buildings that are in range of an access point can be wirelessly connected to a LAN to give these buildings connectivity. Where computer labs are used in schools, the computers (laptops) could be put on a mobile cart and wheeled from classroom to classroom, provided they are in range of access points. Wired network points would be needed for each of the access points. A WLAN has some specific advantages: It is easier to add or move workstations. It is easier to provide connectivity in areas where it is difficult to lay cable. Installation is fast and easy, and it can eliminate the need to pull cable through walls and ceilings. Access to the network can be from anywhere within range of an access point. Portable or semi permanent buildings can be connected using a WLAN. Although the initial investment required for WLAN hardware can be similar to the cost of wired LAN hardware, installation expenses can be significantly lower. When a facility is located on more than one site (such as on two sides of a road), a directional antenna can be used to avoid digging trenches under roads to connect the sites. In historic buildings where traditional cabling would compromise the faà §ade, a WLAN can avoid the need to drill holes in walls. Long-term cost benefits can be found in dynamic environments requiring frequent moves and changes. Wireless network also have some disadvantages: As the number of computers using the network increases, the data transfer rate to each computer will decrease accordingly. As standards change, it may be necessary to replace wireless cards and/or access points. Lower wireless bandwidth means some applications such as video streaming will be more effective on a wired LAN. Security is more difficult to guarantee and requires configuration. Devices will only operate at a limited distance from an access point, with the distance determined by the standard used and buildings and other obstacles between the access point and the user. Methodology: Solution: find-ip-address To overcome the technical issues take necessary steps to build wireless home network. To solve the wireless range problem with the 802.11b/g, in this network 802.11n wireless standard is chosen. So it will provide wide range of wireless network and it will be enough for small to medium size home. The wireless security is configured so the home wireless network can be protected. To protect wireless security WPA2 personal security encryption is configured and MAC address allocation is also configured so the wireless router will not provide access to any other device and the home wireless clients devices will be secured. The firewall is also enabled on Linksys wireless router so it will provide security from outside. From outside no one can hack your home network and harm the computer systems. The ultimate in wireless security measures, shutting down your network will most certainly prevent outside hackers from breaking in! While impractical to turn off and on the devices frequently, at least consider doing so during travel or extended periods offline. Computer disk drives have been known to suffer from power cycle wear-and-tear, but this is a secondary concern for broadband modems and routers. Summary: To build wireless home network, using this simple three-step approach: 1. Identify the WLAN design thats best for your situation 2. Choose good wireless gear 3. Install gear and test the configured WLAN Wireless offers tangible benefits over traditional wired networking. Each computer you wish to connect to a WLAN must possess a wireless network adapter. Wireless adapters are sometimes also called NICs, short for Network Interface Cards. Wireless adapters for desktop computers are often small PCI cards or sometimes card-like USB adapters. Try to install your wireless router in a central location within the home. The way Wi-Fi networking works, computers closer to the router (generally in the same room or in line of sight) realize better network speed than computers further away. In densely populated areas, its not uncommon for wireless signals from one persons home network to penetrate a neighboring home and interfere with their WLAN. This happens when both households set conflicting communication channels. Fortunately, when configuring an 802.11n router, you can change the channel number employed. For example, you may choose any WLAN channel number between 1 and 11. If you encounter interference from neighbors, you should coordinate channel settings with them. Simply using different channel numbers wont always solve the problem. However, if both parties use a different one of the channel numbers 1, 6 or 11 that will guarantee elimination of cross-WLAN interference. Wireless LANs suffer a few more reliability problems than wired LANs, though perhaps not enough to be a significant concern. 802.11n wireless signals are subject to interference from other home appliances including microwave ovens, cordless telephones, and garage door openers. With careful installation, the likelihood of interference can be minimized. Wireless networking products, particularly those that implement 802.11n are comparatively new. As with any new technology, expect it will take time for these products to mature. Wireless LANs using 802.11n support a maximum theoretical bandwidth of 300 Mbps. Furthermore, Wi-Fi performance is distance sensitive, meaning that maximum performance will degrade on computers farther away from the access point or other communication endpoint. As more wireless devices utilize the WLAN more heavily, performance degrades even further. Overall, the performance of 802.11n is sufficient for home Internet connection sharing and file sharing, but generally not sufficient for home LAN gaming.

Pygmalion :: essays research papers

During the time of the play, Pygmalion, classes in England were seemingly artificial. It is shown very well in Act III during one of Mrs. Higgins’s at-home days the differences between classes. Mrs. and Miss Eynsford Hill claim to be of the upper class and they act as if they are in the upper class to try and impress Henry Higgins during this scene.   Ã‚  Ã‚  Ã‚  Ã‚  Eliza Doolittle is being tutored by Henry Higgins, a professor of phonetics, to speak clearly and correctly; to change from her old flower girl way to a lady of class. Having not been eduacated fairly well and not having learned this â€Å"new† language quite well a remark from Freddy Eynford Hill sends her back into her old ways.   Ã‚  Ã‚  Ã‚  Ã‚  At the being of the conversation, in Act III, Eliza is speaking with pedantic correctness of pronunciation and great beauty of tone. â€Å"How do you do, Mrs. Higgins?[she gasps slightly in making sure of the H in Higgins]....† Eliza starts to go off and loses control of her emotions later on during the conversation when she misconstrues the remark of Freddy Eynsford Hill. She starts to get like her old flower girl self and gets so comfortable that she doesn’t even realize it. Henry jumps into the conversation and stops her and she finally realizes what happens. The Eynsford Hills still seem a little bit puzzled because they have never heard a person of such â€Å"high class† speak in such a manner.   Ã‚  Ã‚  Ã‚  Ã‚  Henry goes on to explain that she is just talking the new small talk and that everybody who is anybody is doing it. The Eynsford Hills being the rocket scientist that they are don’t realize that Higgins is not telling them the truth about Eliza and who she really is. They want to be accepted so much by him and his upper class friends that they believe him and start talking in the same way. On the way out the door Clara imitates the silly nonsense and laughs as she says goodbye.   Ã‚  Ã‚  Ã‚  Ã‚  Alfred Doolittle is another character in the play that doesn’t really show a class distinction. When you first see Alfred in Act II he is a trash man. â€Å"He is an elderly but vigorous dustman , clad in the costume of his profession, including a hat with a back brim covering his neck and shoulders,† states Shaw (the author of Pygmalion).   Ã‚  Ã‚  Ã‚  Ã‚  While his clothing and his appearance are disapproving, his language of persuasion is very appealing. Higgins is surprised by the way that Doolittle speaks and becomes somewhat interesting.

Oedipus – a True Leader Is Born

A leader is like a guide; because others depend on him, he must be confident in his own abilities and be able to direct his followers towards their goal. While anyone can be a leader, a true leader is born, not made; although certain qualities can be taught, a natural-born leader possesses the intrinsic skill to command respect in a way a taught leader cannot. In Sophocles’ Oedipus the King, Oedipus shows himself to be a true leader. He is a great king and leader, as shown through the eradication of the Sphinx and the cleansing of the city’s miasma.While Oedipus is ultimately the source of the city’s woes, he still did all he could to find and purge the pollution from the city. Unlike Oedipus, Moses was not a natural-born leader. Moses did not possess faculty of commanding others; rather, his capacity for leadership was endowed upon him by God. Before his life changing encounter with God, he was a meek man, aware of the injustice of the world but incapable of doi ng anything about it. Thus, in comparison with Oedipus, Moses cannot be called a true leader. Their difference lies essentially in the source of their powers. Oedipus is born to be a leader; he is completely self-reliant.No divine involvement bestows his abilities upon him. More than anything, the gods are against him. Since his father violated the sacred pact between the guest and host, he has been cursed and doomed to a tragic end. Despite this, Oedipus’ innate skills are still able to bring him to his high status. With his intellect, he correctly answers the Sphinx’s riddle that countless others failed to solve, thus saving Thebes from the Sphinx and becoming king. Oedipus also possesses great resourcefulness. With all of the problems plaguing Thebes, he is not foolish enough to try to do everything by himself.He always knew the right people to ask for help. For example, he sends Creon to ask the Oracle of Delphi the reason behind the plagues. Also, after hitting a dead-end, he sends for the blind prophet, Tiresias, to aid in the investigation of Laius’ murder. Moses, on the other hand, is not a born leader. While Moses killed an Egyptian in defense of a Hebrew, he only wanted to pretend it never happened. He was incapable of leading the Hebrews in rebellion; the only thing he could lead was sheep. He even admits his inability, making excuses to God and imploring, â€Å"’O my Lord, please send someone else. ’(Ex. 4:13). It was only with God’s instruction that Moses was able to become a leader with the power to free the Hebrews. Compared to Oedipus, who relies on his own powers, Moses pales in comparison, as everything he does is reliant on God. God commands Moses to free the Hebrews; He allows Moses to perform miracles; He sends the ten plagues and parts the Red Sea. Moses just uses His words and power, essentially acting as His puppet and the bridge between Him and His people. The distinction in strength between t he two leaders is apparent through their respective relationships with their followers.Like a true leader, Oedipus has an overwhelming presence and commands the respect of his followers. When Oedipus says he will find and bring to justice Laius’ murderer, the citizens never waver or question him. Whether or not Oedipus has proof of god to support him does not matter to them; in fact, they even believe in Oedipus over Tiresias, saying, But that a mortal seer [Tiresias] knows more than I know–where Hath this been proven? Or how without sign assured, can I blame Him [Oedipus] who saved our State when the winged songstress came, Tested and tried in the light of us all, like gold assayed?How can I now assent when a crime is on Oedipus laid? (Socrates) Although Moses is also a successful leader in that he reaches his goal, his relationship with his followers is frail. When Moses goes up the mountain to receive the Ten Commandments from God, problems arise following his absen ce. Without his presence, his followers stray from the right path and begin worshipping a golden calf, which contradicts their covenant with God. Moses can not hold the complete faith of his followers like Oedipus can. While anyone has the potential to become a leader, a true leader is one that is born.Without God, Moses would be nothing more than another of the Hebrews oppressed by the Egyptians. In reality, God could have chosen any of the other Hebrews and led them to the same result. Moses cannot be called a true leader because, although he leads the Hebrews, he is nothing more than an intermediary for God. The true leader is actually God. He is Moses’ guide and the perpetrator of the liberation of the Hebrews. Oedipus, on the other hand, proves himself to be a true leader. He achieves everything—defeating the Sphinx, becoming king, saving Thebes—through his own abilities and controls the complete respect of his followers.

Free Essays on The Trumpet

When I was a young child in fifth grade, my parents encouraged me to join the school band. The instruments I had to choose from included: the trombone, the trumpet, the clarinet, the flute, and percussion. The trombone interested me most. My bandleader felt that I would be better suited playing the trumpet. My first trumpet was a beginner trumpet. When I pick it up today, it sounds pretty sorry! I now own a Vincent Bach silver trumpet that in my opinion is much easier to play and sounds more professional. This trumpet is an intermediate trumpet, and the silver provides an advantage to the sound. Besides being an attractive trumpet, silver plating slightly brightens the sound. Gold plating resists tarnishing and darkens the sound. I have given some thought to my next instrument, which I hope will be a professional trumpet. I researched the following trumpets:  · The 180 Series trumpet  · The LR180 Series trumpet  · LT180 Series trumpet The 180 Series trumpet is the most popular of all Bach Stradivarius trumpets for good all-around playing. It features standard weight body and bell, and standard construction #25 mouth pipe. Most musicians prefer the 180 with .459" medium-large bore, #37 bell flare, and silver-plated finish. If I were to get this trumpet it would be a great trumpet, but the LT180 Series or LR180 Series would be more desirable. An LR180 Series trumpet has a unique configuration offering the quick response of a lightweight model with the projection of a standard weight bell. It features lightweight body, standard weight bell, and reversed construction #25LR mouth pipe. I think it would be an excellent trumpet to have in college, because of the lightweight. Players seeking a lively trumpet with quick response prefer the LT180 Series. This trumpet has a lightweight body and bell, and standard construction #25 mouth pipe.
