...Article – The real way to build a social network Reid Hoffman and Ben Casnocha This article is from the February 6, 2012 issue of Fortune. “Networking” is a very common word now-a-days. It is not only about what you know, but it is also about who you know. Reid Hoffman is a partner at Greylock and founder and executive chairman at LinkedIn Ben Casnocha is an award-winning entrepreneur and author. The article talks about building a social network. It tells about building a relationship with others requires two important abilities. First, one should be able to see the world from other perspective. Second, one should be able to collaborate with other by helping them and not by thinking what he/she would get in return. Keith Ferrazzi, author, New York Times #1 bestsellers, Who's Got Your Back and Never Eat Alone quotes: “The currency of real networking is not greed but generosity.” The article then goes on and describe the ways in which one can diversify and strength his/her network. The author describes that the best way to increase the efficiency of your network is by strengthening your relationship with people who you already have in your network. The article also talks about the weak ties and how they can help you increase the effectiveness of your network. Weak ties are normally outside one’s inner circle and hence have a greater probability to give new information that your close relationship might not. The article then goes on to talk about the three degree of separation...

...How to Protect Home Wireless Network The following are methods used in ensuring home wireless networks are safe and secure from unauthorized access. Check the SSID (Service Set Identifier) if it is the default one, and change to something unique. Manufacturers give their wireless routers a preset SSID. Changing the SSID to something unique is a good practice. The default SSID will show to a hacker that a novice set the network and that the other settings such as passwords are default. Enable encryption of the wireless router. The routers often come with the encryption disabled. Use 128-bit encryption or higher to increase security. The recommended encryption scheme is WPA2 encryption. Also use longer passwords that use a combination of numbers, letters, and symbols. Enable the MAC Address Filter so that the wireless router screens MAC addresses of devices that connect to the wireless network. The wireless network can be configured in such way that it accepts a connection from wireless devices with allowed MAC addresses. Change the default access password that comes with the wireless router. The default password is for administering the router’s settings. Use a random sequence of the maximum possible character length. Firewalls protect networks from hardware-based and software-based harmful intrusion. The recommended setting is that you enable the built-in firewall of the wireless router. Turn off the setting that allows administering the router through a wireless connection to...

...Question: Write a 2-3 page paper describing the OSI model and how it relates to a network. Your response should include answers to the following: • On which layers of the OSI model do WAN protocols operate? • What are some of these protocols? • On which OSI layers do switches and routers operate? • If routers reside at more than one layer, what is the difference between the OSI layers? Introduction: The OSI model was introduced in 1984. Although it was designed to be an abstract model, the OSI model remains a practical framework for today's key network technologies like Ethernet and protocols like IP. The OSI model defines internetworking in terms of a vertical stack of seven layers. The upper layers of the OSI model represent software that implements network services like encryption and connection management. The lower layers of the OSI model implement more primitive, hardware-oriented functions like routing, addressing, and flow control. In the OSI model, data communication starts with the top layer at the sending side, travels down the OSI model stack to the bottom layer, then traverses the network connection to the bottom layer on the receiving side, and up its OSI model stack. How OSI model relates to a network: Information being transferred from a software application in one computer system to a software application in another must pass through the OSI layers. For example, if a software application in System A has information to transmit to a software application...

...How to Protect Your Network From Cyber Attacks There are three measures network administrators can take to avoid the types of network attacks that plagued U.S. and South Korean websites including www.whitehouse.gov, NASDAQ, NYSE, Yahoo!'s financial page and the Washington Post. The three areas to focus on are network based mitigation, host based mitigation and proactive measures. Network based mitigation * Install IDS/IPS with the ability to track floods (such as SYN, ICMP, etc.) * Install a firewall that has the ability to drop packets rather than have them reach the internal server. The nature of a web server is such that you will allow HTTP to the server from the Internet. You will need to monitor your server to know where to block traffic. * Have contact numbers for your ISP's emergency management team (or response team, or the team that is able to respond to such an event). You will need to contact them in order to prevent the attack from reaching your network's perimeter in the first place. Host based mitigation * Ensure that HTTP open sessions time out at a reasonable time. When under attack, you will want to reduce this number. * Ensure that TCP also time out at a reasonable time. * Install a host-based firewall to prevent HTTP threads from spawning for attack packets Proactive measures For those with the know-how, it would be possible to "fight back" with programs that can neutralize the threat. This method is used mostly by networks...

...Canadian Economic History Final How Institutional Settings matter Tri-networks integration and IPTV Student ID No. 1310511012 Student Name Zhang Qiyue (Emily) School Suzhou University Major Field International Finance Advisor Sam Yu Date Janurary 2016 How Institutional Settings matter Tri-networks integration and IPTV Abstracts: This paper will first make a brief introduction on IPTV industry and its present status of development in China. The promotion of IPTV is affected not only by the technology and market demand, but also by the regulatory policy. Policy barriers caused by yield game between telecom operators and State Administration of Radio, Film and Television (SARFT) about profit allocation hindered the development of IPTV. We use the Stackelberg model to analyze the yield game between telecom operators and SARFT. With deep integration between the industry, the traditional regulatory framework should also advance with the times, be replaced by a more flexible integration framework, so as to promote the development of IPTV and other integration of services. However, the pace of development is far below expectations in China. Many experts pointed out that there were few technical problems existing in IPTV, which leaves the main crux to its institutional settings. We will also discuss how institutional settings matter the industry, find out proper...

...Case Analysis- Hewlett-Packard Company: Network Printer Design for Universality radical B02: 1. In what way is a Universal power impart a postponement strategy? Ans: The power depict requirements for printers were different in North the States and Europe. For North America a 110-volt add was needed and for Europe it was 220-volt turn in. Due to want lead sequence of manufacturing, HP had to specify the requirements for each subjectwrite at least 14 weeks ahead. This often gave rise to wide demand forecasts which created huge inventories for one location while create lost gross revenue due to stick-outs in a nonher. Eg: Case of Viper where growth was sold out in Europe but was less(prenominal) in demand in North America. Universal tycoon Supply pass on solve this problem as the system of rules design takes care of both types of input supply (110V and 220V). indeed it can be sold in both American and European markets. As such the marketing team does not have to specify the individual forecasts for these markets a long time ahead. On the contrary, only the worldwide product demand has to be made. Individual market demand forecast can be delayed or postponed for two and half months. This will serve well create more accurate forecasts and help prevent hole errors. 2. What are the personifys and benefits of a universal power supply (feel free to make assumptions)? Ans: Costs: The primary cost involved in developing the Universal power supply printer vis-a-vis...

...How has the Growth of the Internet Supported or Hindered Castells Concept of a Network Society? Castells concept of a network society is an interpretation of a ‘new society’, one which has developed from the earlier information society. Within this interpretation, Castells states how society has shifted from ‘vertically organized, rational and structured activities to networking forms of activity’. These networking forms of activity provide greater flexibility and adaptability as networks have the ability to organize resources and activities whilst reacting to the environment, transforming themselves rather than clashing with other structures (Castells, 1996). Castells concept explores the social, political, economic and cultural impact of network technologies and the implications of networking activities. According to Castells, the network society has evolved through a growth in networks, induced by new technologies including microelectronics, digitally processed information and communications technology. These technologies represent a new dimension in society providing a modern infrastructure supporting emerging networks. Whilst Castells explains a growth in social networks, he recognizes that they are not a new form of social organization but a ‘key feature in social morphology’. Therefore, rather than describing existing social networks, the network society highlights the impact of networks which manage information using modern electronic technologies. The...

...N. Justin Bernard Management 6740 Executive Summary “Wireless Networking and How to Keep Yourself Protected” Technology is consistently evolving and changing and wireless networking is no exception. There are constant updates as well as vulnerabilities in wireless networking, and my goal is to inform you of those vulnerabilities to help you stay protected from them. Wired Equivalent Protocol (WEP) was the original wireless security protocol. WEP was flawed in numerous ways and hackers were able to get information in minutes. WPAv1 was then introduced as an interim replacement because WEP was that flawed. WPAv1 was made to improve on the secure wireless networks and also used a newer and more improved algorithm. When WPAv2 was finally released, many devices began to be created to be compatible with the AES algorithm WPAv2 uses. There still have not been any major hacks or attacks on a WPAv2-AES network that would cause the Wi-Fi alliance look into using another algorithm a replacement. WPAv1 is too easy to hack so it is not recommended and WPAv1 is now susceptible to multiple types of attacks. There are several different ways you can help to protect yourself and your information. Verify your spam in your e-mail to make sure a file accidentally was not forwarded to spam. There are also others to improve your security. The length of your passkey is very important in security, as well as keeping an up-to-date anti-virus and staying up-to-date on all the latest hacks, cracks, and...
