Explain the function and purpose of the Domain Name System.12. Explain how the TCP/IP utilities can be used to troubleshoot problems.STUDENT OUTCOMES1. Use a network connection.2. Identify a computer and its workgroup on a network.3. Share a printer, a folder on a hard drive, and an entire hard drive.4. Use file and folder permissions, if possible.5. Use the net commands to gather information about your computer.6. Map a drive on a network from the command line and GUI.7. Use two TCP/IP Utilities.CHAPTER SUMMARY1. When you connect computers together, you create what is known as a LAN (local area network).2. A server is a computer that provides shared resources. A client is a computer that accesses the shared resources provided by a server. Resources are the parts of the computer you share.3. The standard model for networks with more than 10 users is a server-based network. It is one in which network functions are provided by a computer that is a dedicated server.4. For networks with fewer than 10 users, the model is a peer-to-peer network, in which all computers are equal. Each computer can function as either a client or server.Carolyn Z. Gillay, Bette A.

A WAN (wide area network) consists of computers that use long-range telecommunication links toconnect the networked computers over long distances.6. A network interface card (NIC) is required to set up a network.7. The NIC must match your bus architecture slot as well as the type of cable used to connect your network.8. You must have the proper networking software for your network to work.9. A simple network has three parts: the hardware, the software, and the network administrator.10. All computers on a network must use the same protocol. A protocol is a set of rules that allows computers to connect with one another and exchange information.11. In a peer-to-peer network, you must name your computer as well as your workgroup. The workgroup name must be identical on all computers in the workgroup.12. There are two parts to sharing resources: the client and the server. The server has the resource. The client is the computer that wishes to access the resource.13. When you share devices, any computer on the network can use that device.14. A firewall is a set of programs, located at a network gateway server that protects the resources of a private network from users from other networks.15. A gateway is a network point that acts as an entrance to another network.16. Common shared devices include printers, drives, and folders.17. The computer that has the resource must first share it so that others on the network can access it. You must name your shared resource. Others on the network will access it by its shared name.18. My Network Places is a tool to browse the network.19. A port is a connection. The parallel port on your computer is called LPT1. Normally, if you physically connect a printer, it shows up on the port called LPT1.20. Access control is the process of authorizing users, groups, and computers the ability to access objects files, folders, and devices) on the network.21. If you are using the NTFS file system, you can set permissions and rights on individual files and folders. However, you must first clear the Simple file sharing check box to access these features.22. Permissions determine which users can access which objects (files and folders and devices) and what kinds of access that user will have to those objects.23. An administrative share allows administrators to connect the root directory of a drive over the network. It used syntax of drive letter$, such as D$ or E.24. There is a series of commands that begin with net that deal with network management at the command line.25. Each of these commands use the syntax of net command in which you specify one of the specific net commands substitute the actual command for command.26. The NET VIEW command displays a list of resources being shared on a computer.27. Once a drive has been shared, you may assign a drive letter to it. This act is called mapping a drive.28. The NET USE command is the command line utility that allows you to map drives.29. A drive alias assigned with the NET USE command may or may not be “persistent’. Meaning that the connections created may or may not remain in effect after shutting down the computer.30. You may use the Administrative share to access a drive that is not explicitly shared.Carolyn Z. Gillay, Bette A.

You may map a drive using Windows Explorer or My Computer.32. The Internet is a network of networks. You can use the Internet to use email and access chat lines and forums. You may connect to the World Wide Web.33. The Web is an interconnected collection of Web sites that holds pages of text and graphics in a form recognized by the Web. These pages are linked to one another and to individual files. The Web is a collection of standards and protocols used to access information on the Internet. Using the Web requires a browser.34. The Web uses three standards: URL (uniform resource locator), HTML (hypertext markup language), and a method of access such as HTTP (hypertext transfer protocol).35. URLs are a standard format for
