    Intro to Networking (See Chapter 20)

      a. Two general categories for computer networks are _________ and __________.

      b. Linux networks most commonly run on a network architecture called ____________

          (or __________________), which has three popular speeds, __________,

          ________________, and _________________.

       c. To connect computers to the Internet, they must be configured to use the ______ protocol
           to connect them to a server or router provided by an ISP. (in most cases). Common
           systems to connect computers on a local network to routers or servers on a wide area network
           include _________ connections, through a telephone line, faster _________ connections through

           a telephone line, _____________, _____________, and ______________ connections.

       d.  Each computer on the network must have a unique identification. Numerical addresses
            are translated into alphanumeric names called ______________. Single or grouped
            servers are identified by name and accessed over the World Wide Web through

       e. Internet domain names were created to give an easy to use system to find services in something
           other than an IP address.
    The browser, itself, can identify a computer host through either the IP
           address or the domain name.; For instance, see if you can find the numerical address associated
           with ______________________. If you open a web browser and enter
           this IP address in the URL window, you should see the same result as when you enter the www
           domain name.

        f. Under the Domain Name System, there are six top-level domain extensions:

           ____ ____ ____ ____ ____ ____

    for a tabular list and
 for more information about
          the domain name system.

          Internet domain names are also called _____________________________________. These
          should no t be confused with the Microsoft domain terminology developed for Windows NT.
          Simple Microsoft workgroup and domain names are not visible over the Internet. They are
          similar to Linux hostnames, and are defined through a protocol called NETBIOS. With
          Windows 2000 Server, Microsoft added support for true Internet domain names.

       g.  On Ethernet networks, each network adapter card is identified by a unique string called a

            ____________. How can you find this string for the network card in your computer?


        h.   Electronic information is sent from computer to computer
              with these cards through a seven-layer system called ____________. (See Jang, p.610 and
              this section of the MCMCSE Network + Study Guide.)

              OSI stands for ______________________________. Try this OSI practice test.

         i. The TCP/IP model for networking includes ___ layers. (See Jang, p. 613).

             Major protocols that work under the TCP/IP model include ____, _____,

             _____, _____, _____. (See Jang, p. 614 for a more complete list.)

             What are the TCP/IP transport-level protocols? _____ ______

             What are the TCP/IP network-level protocols? _____ ______

             What are the TCP/IP link-level protocols? _____ ______ ______ ______

             (See this link for more information.)

         j.  Define these TCP/IP network services:

             Domain Name System: ____________________________________________


             Dynamic Host Configuration Protocol ________________________________


           Address Resolution Protocol  _______________________________________


        h.   Tp set up a computer on a TCP/IP network, you need ___________

               (manually assigned by an administrator or automatically assigned by ____,

               a ______  address and a ___________.   Additionally, to connect to sites on

               the Internet, you need ___________.

               The current standard in use for IP addressing is called ____.   IP addresses can

                be expressed in two formats ___________   and  __________.

               Addresses under  this standard are expressed in ___ columns with
                numerical values  between __   and ____.

          i.     IP addresses are divided into ___ classes.  (See Jang, p. 618.

                  What class do the addresses on our classroom computers belong to? _____

               Do the classroom computers use public or private addresses?   _______

                   How would you write the IP address of your classroom computer in binary notation?


             j.   Experiment with PING and IFCONFIG commands.   Change your adapter's IP address.  Check
                   the graphic redhat-config-network application and see if the change carries over.

                    Stop and restart the network using the Service [servicename] command.

                    After making sure that your Sendmail server is disabled, change the hostname of
                     your computer, in preparation for the next set of exercises.

                     Review network mask settings (see Jang, p. 629). 

    6. Networking Challenges


    See if you can configure your Linux home directory as a read-only shared folder visible
    from a Windows XP client. (To do this, you may need to change the hostname for
    your computer. )

    7. Linux Practical Application Exercises

    8,  Backing up with Tar and CPIO (See Jang, Chapter 14)


Work on Linux class projects

Read/review Jang, Chapters 21 (Managing Linux on your LAN),
Chapter 14 (Backing Up)
Look over sample Chapter 6 on command-line options from the Hello Linux website.
