This document is exclusive property of Cisco Systems, Inc. Permission is granted to print and copythis document for non-commercial distribution and exclusive use by instructors in the CCNA 1:Networking Basics course as part of an official Cisco Networking Academy Program.Lab 1.1.2 PC HardwareObjective•Become familiar with the basic peripheral components of a PC computer system.•Identify PC connections including network attachment.•Examine the internal PC configuration and identify major components.•Observe the boot process for the Windows operating system.•Use the Control Panel to find out information about the PC.BackgroundKnowing the components of a PC is valuable when troubleshooting.

This knowledge is alsoimportant to success in the networking field.Before beginning, the instructor or lab assistant should have a typical desktop PC available with allperipherals. Peripherals include the keyboard, monitor, mouse, speakers or head phones, a networkinterface card (NIC), and a network cable.

The system unit cover should be removed. If the cover isnot removed, the tools should be provided to remove it. Work individually or in teams. In addition, theinstructor needs to identify the location of the A+ or PC hardware training materials.Step 1 Examine the computer and peripheral componentsExamine the computer and peripheral components both front and back.Note: The components and configuration of the PC may vary.What are the manufacturer and model number of this computer?Manufacturer:Model Number:What are the major external components of the PC including the peripherals?Component NameManufacturer / Description / Characteristics1.2.3.4.5.1-2CCNA 1: Networking Basics v 3.1 - Lab 1.1.2Copyright  2003, Cisco Systems, Inc.Step 2 Remove the PC system unit cover and examine internal componentsList at least 8 major internal components inside the system unit.

Observe the boot process.The computer should boot to the Windows operating system.

If the computer does not boot, contactthe lab assistant.Did the Windows operating system boot correctly? ____________________Did the screen show how much memory there was as the system was booting? _______________Step 4 Gather basic information about the computer CPU and RAMGather basic information about the computer CPU and memory. The instruction to complete this stepmay vary slightly depending on the version of Windows.

Consult with the instructor if lab assistanceif required.Click the Start button. Select Settings then Control Panel. Click on the System icon and then theGeneral tab. View the information about the computer using the operating system.What is the Central Processing Unit? _____________________What is the speed in MHz of the CPU? ____________________How much RAM is installed? ___________________________This concludes the lab. All equipment should be returned to the original state or as directed by theinstructor.2-2CCNA 1: Networking Basics v 3.1 - Lab 1.1.2Copyright  2003, Cisco Systems, Inc.Lab 1.1.6 PC Network TCP/IP ConfigurationObjective•Identify tools used to discover a computer network configuration with various operating systems.•Gather information including connection, host name, Layer 2 MAC address and Layer 3 TCP/IPnetwork address information.•Compare network information to other PCs on the network.BackgroundThis lab assumes the use of any version of Windows.

This is a non-destructive lab and can be doneon any machine without concern of changing the system configuration.Ideally, this lab is performed in a classroom or other LAN environment that connects to the Internet.This lab can be done from a single remote connection via a modem or DSL-type connection. Theinstructor will furnish IP addresses.In the following instructions the lab runs twice.

The two runs reflect the operating system differencesbetween the Windows 95/98/ME systems and Windows NT/2000/XP systems. Students shouldperform the lab on both types of systems if possible.Note: All users complete Step 1Step 1 Connect into the InternetEstablish and verify connectivity to the Internet. This ensures the computer has an IP address.Note: Windows 95/98/Me users complete Steps 2 through 6.Step 2 Gather basic TCP/IP configuration informationUsing the taskbar, choose Start then Run. The following box will appear.

Type winipcfg and pressthe Enter key. Winipcfg spelling is critical while case is not. It is short for Windows IPConfiguration.This first screen shows the Adapter Address, or MAC address of the computer. The first screen alsoshows IP Address, Subnet Mask, and the Default Gateway. The following graphic shows the basic IPConfiguration screen. Select the correct adapter if more than one is listed.1-6CCNA 1: Networking Basics v 3.1 - Lab 1.1.6Copyright  2003, Cisco Systems, Inc.The IP address and the default gateway should be in the same network or subnet. Otherwise, thishost would not be able to communicate outside the network.

In the previous figure the subnet masktells us that the first three octets must be the same to be in the same network. IP addressing will bediscussed in Module 9.Note: If this computer is on a LAN, the default gateway might not be seen if it is running behinda Proxy Server. Record the following information for this computer:IP address: _________________________________________Subnet Mask: _______________________________________Default Gateway: _____________________________________Step 3 Compare the TCP/IP configurationIf this computer is on a LAN, compare the information on several machines.Are there any similarities? ______________________________________________________What is similar about the IP addresses? ____________________________________________What is similar about the default gateways? _________________________________________What is similar about the MAC addresses? ___________________________________The IP addresses should share the same network portion.

All machines in the LAN should share thesame default gateway. While not a requirement, most LAN administrators try to standardizecomponents like NICs. Therefore, all machines may share the first three Hex pairs in the adapteraddress. These three pairs identify the manufacturer of the adapter.Record a couple of the IP Addresses__________________________________________________________________________Step 4 Verify selection of network adapterThe adapter model of this computer should be displayed in the box at the top of the screen. Use thedrop-down arrow in that box to see if there are any other configurations for this adapter, such asPPP.

This could be true for a modem if this computer connects to the Internet with a dial-up account.On a server, it is possible to find another NIC or a machine with both a NIC and a modem. Thefollowing figure shows an AOL modem IP configuration screen. Notice that there is no IP address inthe figure. This is what a home system could look like if the user did not log on to the Internetconnection.2-6CCNA 1: Networking Basics v 3.1 - Lab 1.1.6Copyright  2003, Cisco Systems, Inc.Be sure to return to the adapter that displays the NIC or modem data with an IP addressStep 5 Check additional TCP/IP configuration informationClick on the More Info >> button. The next figure shows the detailed IP Configuration screen.The More Info button displays the Host Name, which includes the computer name and NetBIOSname. It also displays the DHCP server address, if used, and the date the IP lease starts and ends.Look over the remaining information.

Entries for DNS and WINS servers may also be displayed.These entries are used in name resolution.3-6CCNA 1: Networking Basics v 3.1 - Lab 1.1.6Copyright  2003, Cisco Systems, Inc.Write down the IP addresses of any servers listed: _____________________________________________________________________________________________________________Write down the computer Host Name: _____________________________________________Write down the Host Names of a couple of other computers: _____________________________Do all of the servers and workstations share the same network portion of the IP address as thestudent workstation? _____________________Note: It would not be unusual for some or all of the servers and workstations to be in anothernetwork.

It means that the default gateway of this computer is going to forward requests to theother network.Step 6 Close the screen when finished examining network settingsRepeat the previous steps as necessary to make sure that there are no problems in returning to, andinterpreting, this screen.Note: Windows NT/2000/XP users complete Steps 7 through 11.Step 7 Gather TCP/IP configuration informationUse the Start menu to open the Command Prompt, an MS-DOS-like window. Press Start >Programs > Accessories > Command Prompt or Start > Programs > Command Prompt.The following figure shows the Command screen.

Type ipconfig and press the Enter key. Thespelling of ipconfig is critical while case is not. It is short for IP Configuration.This first screen shows the IP address, subnet mask, and default gateway. The IP address and thedefault gateway should be in the same network or subnet, otherwise this host would not be able tocommunicate outside the network. In the figure the subnet mask tells us that the first three octetsmust be the same to be in the same network.Note: If this computer is on a LAN, the default gateway might not be seen if it is runningbehind a Proxy Server.Step 8 Record the following TCP/IP information for this computerIP address: _________________________________________________________________Subnet Mask: _______________________________________________________________Default Gateway: _____________________________________________________________4-6CCNA 1: Networking Basics v 3.1 - Lab 1.1.6Copyright  2003, Cisco Systems, Inc.Step 9 Compare the TCP/IP configuration of this computer to others on the LANIf this computer is on a LAN, compare the information of several machines.Are there any similarities? ______________________________________________________What is similar about the IP addresses? ____________________________________________What is similar about the default gateways? _________________________________________The IP addresses should share the same network portion.
