...Networking in My Life and Career Angel Salvador Maldonado DeVry University Author Note This paper was prepared for CEIS-100 taught by Professor Reinaldo Fernandez. Course Project Week #: 2 Networking in My Life and Career A network is defined as a group of computers that are connected to share information. An NIC is a Network Interface Card. It is the physical component of a computer that allows a computer to connect to a network. Three types of media used for network connections are cable television coaxial, fiber optic cable and wireless connections. There have often been times when I have had to access my home wireless internet network and have not been able too. I start to troubleshoot by disconnecting and re connecting to the wireless network in the Open Network and Sharing Center. If that does not work, I check my wireless router to see if the lights on the router are green indicating that it is working properly. If there is a red or orange light on the router, I unplug the power source of the router and let it reset. This usually resolves the issue. My career goal is to become a Network System Administrator. That being said, I will be dealing with networks on a daily basis. A Network System Administrator is responsible for designing, installing, maintaining and upgrading networks in businesses of different sizes. I still have not taken any networking classes. I do know that by the time I obtain my Associates in Network Systems Administration I will have gained...

...headquarters. Until now, its networks have relied entirely on wired connections. The company’s CIO (chief information officer) decided long ago that she would wait until wireless technology “settled down” before investing in it. 1. What can you tell her about the wireless standards that might convince her that now is the time to adopt wireless technology? There are many advantages to wireless networks. Some advantages of a wireless network are convenience, mobility, ease of set up, the cheaper cost in the long run, and with the newest 802.11 standards the throughput could be just as good as or even better than some Ethernet connections without the hustle of all the wires. 2. Also, what can you tell her to convince her that wireless networking could improve the company’s productivity? With the implication of a wireless network it opens up more options for employees such as the ability to use laptops and their smartphones to complete work so it can be completed however they would like. 3. Which employees could make best use of wireless connections and how? The production, order fulfillment, and research departments would probably benefit the most from the wireless connections so that they can work while on the go and easily update any data even when outside the office. 4. In what type of situations would all employees benefit from wireless...

...1. List two advantages of wireless networking. User mobility in the workplace, and cost effective networking media for use in areas that are difficult or too costly to wire. 2. What are the three areas defined for the IEEE 802.11 standard? Physical Layer (PHY): The method of transmitting the data, which may be either RF or infrared (although infrared is rarely used.) Medium Access Control (MAC): The reliability of the data service, access control to the shared wireless medium, protecting the privacy of the transmitted data. MAC management protocols and services: Authentication, association, data delivery, and privacy. 3. What is an ad hoc network? In this network, the wireless clients (stations) communicate directly with each other. 4. What is the purpose of an Extended Service Set? By adding multiple access points to the network, the range of mobility of a wireless client in the LAN is extended. 5. What are the four physical layer technologies being used in 802.11 wireless networking? Direct Sequence Spread Spectrum (DSSS), Frequency Hopping Spread Spectrum (FHSS); Infrared, and Orthogonal Frequency Division Multiplexing (OFDM) 6. Describe the frequency spectrum for the DSSS channels in 802.11b wireless networking. It implements 14 channels (each consuming 22 MHz) over approximately 90 MHz of RF spectrum in the 2.4 GHz ISM (industrial, scientific, and medical) band. 7. Define a pseudorandom sequence as it applies to FHSS. Pseudorandom means the sequence...

...I. Computer Dynamics Computer Dynamics is a microcomputer software development company that has a 300-computer network. The company is located in three adjacent five-story buildings in an office park, with about 100 computers in each building. Each building is approximately 90 feet long by 50 feet wide. They are set about 100 feet apart. The current network is poorly design for its current needs and must be completely replaced. Describe the network you would recommend and how it would be configured with the goal of building a new network that will support the company’s needs for the next 3 years with few additional investments. Figure 11.16 provides a list of equipment and costs you can use to build your network. You will need to make some assumptions, so be sure to document your assumptions and explain why you have designed the network in this way. We need 5 switches has 24 ports each in each floor to create the access layer of the network and also we need 100 Cat 5 cables in each floor to connect the computer to the switches. All the switches in the four floors are connected to core layer 3 switch using fiber optic cable to handle this huge number of connection. creating Vlans on each access layer switches to give privileges to each group of users can reduce the process in the core switches. then we can create a link between the core switch and the router. The router have T3 wan interface and connection with ISP pop to provide 44.370 Mbps can be pretty good for 300 users...

Business Networking

...Business networking is a socioeconomic business activity by which groups of like-minded businesspeople recognize, create, or act upon business opportunities. A business network is a type of business social network whose reason for existing is business activity. There are several prominent business networking organizations that create models of business networking activity that, when followed, allow the business person to build new business relationships and generate business opportunities at the same time. A professional network service is an implementation of information technology in support of business networking. Many business people contend business networking is a more cost-effective method of generating new business than advertising or public relations efforts. This is because business networking is a low-cost activity that involves more personal commitment than company money. Country-specific examples of informal networking are guanxi in China, blat in Russia, and Good ol' boy network(US)/Old boy network(UK). In the case of a formal business network, its members may agree to meet weekly or monthly with the purpose of exchanging business leads and referrals with fellow members. To complement this business activity, members often meet outside this circle, on their own time, and build their own one-to-one business relationship with the fellow member. Business networking can be conducted in a local business community, or on a larger scale via the Internet. Business networking...

The Influence of Social Networking Website

...What is Social Networking Website? The definition of social networking is “the relationships that exist between network of people” (Walter & Ribiere, 2004). Today, when we talk about social networking, we think of social networking websites like Facebook, MySpace, and Twitter, which are the top three popular social networking sites in the United States (Alexa.com, 2010). These sites are defined as web-based platforms that allow individuals to build their own profiles and reflect social relations. The users of these sites are able to “articulate a list of other users with whom they share a connection, and view and traverse their list of connections and those made by others within the system” (Boyd &Ellison, 2008). Within the system, the users are able to present themselves, articulate their social networks, and establish or maintain connections with others; moreover, these social networking websites can be oriented toward different fields like work-related, romantic relationship related, interest sharing related, or student community (Ellison, Steinfield & Lampe, 2008). Mostly, users participate in these sites for interaction with their friends or meet new people. With these sites, they provide various features such as profiles, comments, private messaging, photo-sharing, and video-sharing capabilities; moreover, with the improving technology, now users are capable of using mobile phones to achieve online interactions.
