Lab 3.1.5 Building a Peer-to-Peer Network
Step 1: Diagram the network
· Which kind of cable is required for a direct Ethernet connection between the two PCs is crossover cable
Step 2: Document the PCs
PC1 Name: | Komputer 1 |
PC2 Name: | Komputer 2 |
· important that each PC on a network have a unique name because its making easier for users to connect to shared resources and that help to identify other device and its locations
Step 3: Connect the Ethernet cable
· Use the Ethernet crossover cable provided by the instructor. Plug one end of the cable into the Ethernet NIC of PC1.
· Plug the other end of the cable into the Ethernet NIC of PC2. As you insert the cable you shouldhear a click which indicates that the cable connector is properly inserted into the port.
Step 4: Verify physical connectivity
Step 5: Configure IP settings
1. Configure the logical addresses for the two PCs so that they are able to communicate using TCP/IP.On one of the PCs, go to the Control Panel, double click the Network Connections icon, and then right click the connected Local Area Connection icon. Choose Properties from the pull-down menu.
2. Using the scroll bar in the Local Area Connection Properties window, scroll down to highlight Internet Protocol (TCP/IP). Click the Properties button.
3. Select the Use the following IP address radio button and enter the following information:
IP Address | 192.168.1.1 |
Subnet Mask | 255.255.255.0 |
4. Ok.
Step 6: Verify IP connectivity between the two PCs
.

ü Firewall are enabled (ON)
4. If the firewall settings are enabled, click the Off (not recommended) radio button to disable the firewall. The setting will be re-enabled in a later step. Click OK in this dialog box and the following to apply this setting.
5. Now that the two PCs are physically connected and configured correctly with IP addresses, we need to make sure they communicate with each other. The ping command is a simple way to accomplish this task. The ping command is included with the Windows XP operating system.
6. On PC1, go to Start, then Run. Type cmd, and then click OK. A Windows command prompt window will appear as shown in the figure below.
7. At the > prompt, type ping 192.168.1.2 and press Enter. A successful ping will verify the IP connectivity. It should produce results similar to those shown in here.
Step 7: Verify connectivity using My Network Places
1. Do you see an icon for the other PC in your peer-to-peer network?
· Yes I do.
2. What is the name of the other PC?
· Its name is Komputer 2
3. Is it the same name you recorded in Step 2?
· Yes it is
Lab 3.3.3 Determine the MAC Address of a Host
Step 1: Open a Windows command prompt window
Step 2: Use the ipconfig /all command
Step 3: Locate the MAC (physical) address(es) in the output from the ipconfig /all command
Description = xample: VIA Rhine II Fast Ethernet Adapter
Physical Address = eexample: 00-50-2C-A5-F5-73
Step 4: Reflection
a. Why might a computer have more than one MAC address? Jawab :
A computer might have more than one NIC and each NIC will have a unique MAC address. An
example of this would be a laptop that has both an integrated wireless NIC and an Ethernet NIC
b. The sample output from the ipconfig /all command shown previously had only one MAC address.Suppose the output was from a computer that also had wireless Ethernet capability. How might the output change? Jawab:
The MAC address of the wireless adapter will be shown in addition to the MAC address of any wired NIC such as an Ethernet adapter
c. Try disconnecting the cable(s) to your network adapter(s) and use the ipconfig /all command again. What changes do you see? Does the MAC address still display? Will the MAC address ever change?
Jawab:
The output shows that the media (cable) has been disconnected. The IP address went away, but the MAC address is still shown. The MAC address is designed to be permanent. It is programmed into the NIC and is unique for each card.
d. What are other names for the MAC address? Jawab:
Other names for a MAC address include a physical address, hardware address, Ethernet address, burned-in address, a data-link layer address, and a Layer 2 address
Lab 3.3.6 Determine the IP Address of a Computer
Step 1: Determine the IP address of the computer
Locate the IP address and record the finding.
IP address: 192.168.1.100
Why is it important that a computer get an IP address?
It is important for a computer to obtain an IP address (either statically or dynamically using DHCP) so
that it can communicate with computers on other networks
Lab 3.5.2 IP Addresses and Network Communication
Step 1: Connect the PCs to create a peer-to-peer network
Step 2: Verify physical connectivity
Step 3: Configure IP settings for the two PCs
Step 4: Verify IP connectivity between the two PCs
Step 5: Change IP address for PC2
Change the logical IP address for PC2 from 192.168.1.2 to 192.168.2.2 and leave the subnet mask
set to 255.255.255.0. On what network is PC2 now?
Jawab: PC2 is now on the 192.168.2.0 network
Refer back to Step 3c. On what network is PC1? Jawab: PC1 is still on the 192.168.1.0 network
The two PCs are still on the same physical Ethernet network. Are they on the same logical IP
network? jawaban : tidak
Step 6: Test network connectivity between the 2 PCs
At the > prompt, type ping 192.168.2.2 and press Enter. Was it successful? No Why or why not? Jawab: The PCs are now on different networks
What type of networking device would allow the PCs to communicate? Jawab : A router, if placed between the 2 PCs using proper cabling
Step 7: Change IP address for PC1
a. Using the procedure previously described, change the logical IP address for PC1 from 192.168.1.1 to
192.168.2.99 and leave the subnet mask set to 255.255.255.0. On what network is PC1 now? Jawab:
PC1 is now on the 192.168.2.0 network
b. Click OK, which will close the Internet Protocol (TCP/IP) Properties window. Click the Close
button to exit the Local Area Connection Properties window.
c. The two PCs are still on the same physical Ethernet network. Are they on the same logical IP network
now? Jawab: Yes, 192.168.2.0
Step 8: Test network connectivity between the 2 PCs
a. On PC2, go to Start, then Run. Type cmd, and then click OK. A Window command prompt window
will appear.
b. At the > prompt, type ping 192.168.2.99 and press Enter. Was it successful? Jawab :Yes
Why or why not? Jawab : The PCs are now on the same network again – 192.168.2.0
Step 9: (Optional – Use only if the Firewall was originally ENABLED) Re-enable the firewall
Lab 3.6.4 Connect and Configure Hosts
Step 1: Identify Ethernet ports
Step 2: Connect the cable between the PC and the router
Step 3: Assign the PCs an IP address and default gateway
Why do you think the IP addresses are different, but the subnet masks and default gateways are the
same? Jawab:
Each device on the network must have a unique identifier. The IP address is one way of uniquely identifying each network host or device. The default gateway represents the way of communicating with devices that are NOT on your own network
Step 4: Verify the IP address configuration
Are the IP address, subnet mask, and default gateway correct for the second PC? Jawab: Yes
Step 5: Test connectivity between the two PCs
Step 6: Configure the NetBIOS name
How many drive letters are shown in the window that appears? Jawab: The answer depends on the hardware installed, but there will be at least one and most likely two
(hard drive and CD/DVD drive)
Which drive letters are shown? Jawab :
The answer depends on the hardware installed, but normally there is at least a C: drive for the hard
drive and a D: drive for the CD/DVD drive
Step 7: Verify configuration
What command would be used from the command prompt on PC2 to view information about PC1? Jawab: nbtstat –a PC1
Write the command that would be typed on PC2 to view information about PC1, using the IP address
of PC1 instead of the NetBIOS name. jawab: nbtstat –A 192.168.10.3
Does the ping succeed using lower case letters? Jawab : ya
Step 8: (Optional – Use only if the Firewall was originally ENABLED) Re-enable the firewall
Step 9: Return IP Address and NetBIOS Name to original values
Step 10: Reflection
a. Check two or three computers in your lab at school. Complete the following table:
Computer Name = pc2
IP Address & Subnet Mask= 192.168.28.100/ 255.255.255.0
Default Gateway = 192.168.28.0
Either with a classmate assigned to you or by choosing one yourself, share this information with them.
In your opinion, are the names descriptive? LAN
Are all of the computers in the classroom part of the same local network? How could you prove that? jawab: All computers have the same default gateway and they all have similar network addresses
Lab 3.6.5 Sharing Resources
Step 1: Share a folder
Step 2: Map network drives to provide quick and easy access to shared folders
Question: What drive letter did you choose? Folder Elvira
Question: What message is displayed? Why do you think this happened? Jawab : Cannot access this file. Check Security Privileges. The second question is the student’s own opinion
Step 3: Verify work
Step 4: Reflection
a. What are some of the benefits of mapped drives and shared folders in a home or small office
network? untuk menghemat biaya dan sumber daya
b. Which folders cannot be shared? Can you think of reasons why an operating system might not allow
certain types of folders to be shared?
c. A mapped drive provides a pointer to a network resource, but mapped drive letters are said to be
locally significant only. What do you think is meant by locally significant?
