## Part A ## Networking and OSI Model Based on your understanding of the topics covered during the week, answer the following, citing relevant examples wherever possible: * Describe how error checking is handled in the data link layer. Define a check sum and describe how Transport layer protocols implement them to ensure data integrity. Define and describe sequencing. * Describe a network address including its addressing scheme, formats, and alternate names. Define and describe the two parts of a MAC address. Compare Ethernet and Token Ring frames in terms of their operation on a network. * Describe a drawback of analog signals. Describe two benefits of digital signaling that make it worthwhile even though extra signaling pulses are involved. Explain how half-duplex transmissions work. * Describe what frequency division multiplexing (FDM) is and how it works. * Describe variables that may influence the final cost of implementing a certain type of media. Explain the makeup of coaxial cable. Explain the makeup of twisted pair wire and describe the advantages of twisted pair wiring. Explain the makeup of fiber-optic cable and describe the benefits of fiberoptic cabling over copper cabling. * Describe the advantages and disadvantages of using traditional peer-to-peer networks. Describe the advantages client/server networks offer over peer-to-peer networks. Define a network operating system (NOS) and describe the tasks it performs. Describe license tracking in networks. ## Part B ## Project – Network Design ### Network Design Your task is to draft a top-level design of an enterprise-wide telecommunications network for a fictitious company, including LAN topology and WAN infrastructure that will handle a constant stream of traffic between the company offices. The company specifications are as follows: * Locations: Five metropolitan geographic urban location; each location has 120 users over three floors; each Floor dimensions are as follows: Length = 210 feet ft), Height = 8 Ft, and Width = 80 ft * Platforms: Multiple (Windows, Mac, Linux, and Mobile Os) * Topology: Ethernet (Copper, Fiber, and Wi-Fi) * Bandwidth: To be determine by you, the network designer, for inbound and outbound * Servers: To be determined by you, the network designer * Intranet access: IP addresses are 172.17. y.x/24, where y is each location IP segment (use any octet that you wish for each location) and x = 1 to 254 * Internet access: One access using T1 Link at each location; the public IP address is 96.68.111.x, where x = 1 to 5 * Remote virtual private network access for users to telecommute You should budget your time wisely and work on your project throughout the course. If you complete your course activities and use the feedback provided by the instructor, you will be on the right track to complete your project successfully. Hint: Feel free to use any drawing that will depict the physical layout. In this week, create a 4- to 5-page Microsoft Word document in response to the following: * Describe the LAN topology design that will be used at each office. * Provide a checklist of cabling specifications for a cabling contractor. * Include a minimum of two scholarly references to support your cabling and LAN topology choices. * Use the project template to compile your project.
