Since the students will be viewing the curriculum via a computer on a network, and since the curriculum is focused on networking -- the network interface card (NIC) is introduced. Having novice students install the NICs is a fun, fairly easy, and fulfilling lab activity. Again, if the incoming students are already experts on PC hardware this would not be a necessary lab, but for the majority of Academy students this would be an instructive exercise. Most likely you will want to use the 10 PCs on the "back-of-the-lab", semester 2 network for this lab activity.</p> <p>The lab activity requires approximately 15 minutes. This TI relates to CCNA Certification Exam Objectives #3 and #60.</p> </span></td> </tr> </table> </td> </tr> </table> </td> </tr> </table><p>The NIC allows hosts (a host is an individual computer or device on a network) to connect to the network and is, therefore, considered a key component. From time to time, you may need to install a NIC. Some possible situations that may require you to do so include the following:</p><ul type="disc"><li>Adding a NIC to a PC that does not already have one</li><li>Replacing a bad or damaged NIC</li><li>Upgrading from a 10 Mbps NIC to a 10/100 Mbps NIC</li><li>Altering settings on a NIC using a jumper. A jumper is a metal bridge that closes an electrical circuit. Typically, a jumper consists of a plastic plug that fits over a pair of pins</li></ul><table cellpadding="0" cellspacing="0" width="100%" border="0" xmlns:java="http://xml.apache.org/xslt/java"> <tr> <td width="100%"><img height="10" width="1" border="0" src="../../../../../images/ccna/common/transdot.gif"></td> </tr> <tr> <td width="100%"> <table bgcolor="#000000" bordercolor="#000000" cellspacing="0" bordercolorlight="#000000" width="100%" border="0"> <tr> <td width="100%"> <table bgcolor="#FFFFFF" width="100%" cellspacing="0" cellpadding="0" border="0"> <tr> <td> <table bgcolor="#FFFFFF" cellpadding="2" width="100%" border="0"> <tr> <td valign="top"><img height="22" width="22" border="0" src="../../../../../images/ccna/common/icon4.gif"></td><td valign="middle"><span class="cstitle"><a href="#" onClick="javascript:launchReference('knet-v214aRIO125202', 'null', 'null');void(null);">Lab Activity</a></span></td> </tr> <tr> <td valign="top"> </td><td valign="top"><span class="cstext"> <p>In this lab, you will learn how to properly install a NIC in a PC.</p> </span></td> </tr> </table> </td> </tr> </table> </td> </tr> </table> </td> </tr> </table> <p xmlns:java="http://xml.apache.org/xslt/java"> </p><p>In order to perform the installation, you should have the following resources:</p><ul type="disc"><li>Knowledge of how the network card is configured, including jumpers, plug-and-play software, and erasable programmable read-only memory (EPROM).
