Your neighbor started a new construction business. He would like to hire you to set up his computers. His business will use Internet to communicate with clients via email, store backups of data, and access cloud-based accounting software. The office will include two networked computers, which will share a printer and an Internet connection. In addition, he will use a tablet so that he can access the cloud-based accounting software using Wi-Fi. Because of security concerns with using the Internet, he first would like you to install a program(s) designed to protect his computers from various security threats.
a) What types of security measures he should use and why?
b) What are two ways that provide a comprehensive security solution that provides the above security measures?
As a computer and networking consultant to small businesses, you are frequently asked to find solutions to increasing demands for network and Internet access at a business. One business rents offices in a historical building that has strict rules for wiring. They have come to you asking for a solution for providing Wi-Fi access to their guests in the lobby of the building. Research options for a solution and answer the following questions:
Print or save webpages showing two options for a Wi-Fi wireless access point that can mount on the wall or ceiling. For one option, select a device that can receive its power by PoE from the network cable run to the device. For the other option, select a device that requires an electrical cable to the device as well as a network cable.
Print or save two webpages for a splitter that can be mounted near the second wireless access point and that splits the power from data on the network cable. Make sure the power connectors for the splitter and the…

- Specifically, which high-availability DHCP solutions do you believe you would use at your firm, and why? So what is it that improves it so much? Do you know of any drawbacks? Which other possibilities did you consider, and why did you ultimately decide on this one? Would you be able to tell if DHCP was down on your network? How soon would you know if DHCP was down in your house?arrow_forwardQ1 You have temporarily moved to a new area and you would like to use your cell phone.

- Why would home users and especially business users want to use Home Plug instead of WiFi for premises networking? Home Plug has a higher capacity than WiFi. O Home Plug is better for tablets and other portable devices. Home Plug cannot cause interference to other RF devices in the premises. Wi-Fi is vulnerable to snooping and intrusion from outside the premises, while Home Plug runs only over the premises wiring. Submit Response v Question 47 Select the appropriate response Of all of the access technologies listed here, which of these has the greatest speed or bandwidth? DOCSIS over HFC RFOG Google Fiber O Metro Ethernet Submit Response Question 48 Select the appropriate response An cable installer has just finished installing a new 10/100/1000 switch, but receives reports from the customer that servers connected to the new switch seem to be experiencing slow LAN connections. The network administrator checks the port connecting the new switch to the core switch and sees the following…arrow_forwardQuestion 16 A Wireless Wide Area Network (WWAN) is: Question 16 options: A network that Interconnects devices in a short span, generally within a person's reach. A network that connects smaller networks within the same city or town to form a larger network. A network that allows users in a local area to form a network and gain access to the Internet. A network that covers large areas such as neighboring towns and citiesarrow_forwardTanner has paid extra to his cable company for the highest speed of Internet connectivity, but browsing speeds seem slow.

- Which high availability DHCP solutions do you believe would be most suited for usage in your company, and why do you hold these beliefs? What makes it better? Exist any potential drawbacks to this? Why do you prefer this option over the others that are available? When do you think you would first become aware if DHCP was not functioning properly in your network? How quickly would you notice if the DHCP server in your house stopped working?arrow_forwardBecause a river divides the administration and student services buildings, the network in the administration building is linked to the network in the student services building only through five obsolete dial-up modem connections in an access server. This region does not have access to DSL or cable modems. What wifi options are available to the institution for connecting these buildings? Which of the above solutions do you prefer? You're doing projects for two different clients: Thomas Jefferson Community College in Virginia and the Tasty Pelican restaurant in Montreal. You will assist the community college in designing a wireless network for the financial resources team members located in the administration building, as well as determining the best method of connecting the administration building to the student services building. You will assist with the creation of a small private wireless network for the Tasty Pelican restaurant and a public network for the adjacent coffee shop.arrow_forwardExplain the following in your own words: “Which network topology is the best for a school? Also, which means of transmission should be used?” Note: This question has 2 parts. In first part you have to define which topology you will use to connect all departments or buildings of school and why. In second part you will define that through which medium you will connect all departments or buildings of school either wire or wireless and why you are using this why not other one. The best advice I can give regarding network topology is that you should be deeply familiar with the needs and usage requirements. The total number of nodes on the network is one of the primary considerations to account for, as this will dictate whether it’s feasible to use a simpler topology. You may consider different buildings of school campus or different departments of school campus. As I mentioned earlier, no one topology is “best.” Each offers its own set of perks and drawbacks, depending on the…arrow_forward

However, if you exceed the 240 minutes mark, you will have to pay 8 cents for every additional minute The third plan offers you up to 510 minutes of calls between Canada & India for aa fixed monthly fee of 22$ and 5 cents per minute if you exceed the 510 minutes mark In order to choose the package that best suits your needs, you decide to plot a graph…arrow_forward1. Write at least three sentences discussing your experience with LANs, whether wired or wireless. 2. Next, go to the discussion board. If you have a home network, list the similarities and differences between your network and the one described in the article. Mention any ideas you might have gotten from the article about how to improve your home network. This is the article Building a Home Network The two most popular home network types are wireless and Ethernet networks. In both of these types, the router does most of the work by directing the traffic between the connected devices. By connecting a router to your dial-up, DSL or cable modem, you can also allow multiple computers to share one connection to the Internet. If you're going to connect your network to the Internet, you'll need a firewall. A firewall is simply a hardware device or software program that protects your network from malicious users and offensive Web sites, keeping hackers from accessing or destroying your…arrow_forward
