Modern computer system depends on networking for sharing and transferring of data. Basically networking is a collection of different computers and its peripherals that are interconnected by communication channels, which allows us to share information and resources. Networking can be achieved by using networking cables or by wireless technology. The greatest advantage of networking is the unlimited sharing of information and resources between the computers that are included in the network. Below processes demonstrates various steps in customizing an Ethernet cable and interconnecting two laptops using this network cable. Here we use a cross over Ethernet cable for setting up this network. By using a customized Ethernet cable, users can obtain cables of appropriate length that suites their needs.


  1. Collect the necessary components as shown in the “Things you will need” section.
  2. Determine your cable length. Measure the length of the cable that is appropriate for this task and cut the wire by using a wire cutter tool. Make sure your cable is the correct length before cutting.
  3. Remove out shielding and untwist the pairs. Remove carefully one or two inches out shielding of cable at each end with a wire stripping tool. Then untwist the wires from each other so you can work with them. Don’t untwist them beyond what you have exposed; the more untwisted wire you have the worse the problems you can run into.
  4. Arrange in order.
  5. Align the colored wires according to the given diagram and picture.
  6. Trim the wires. Trim all the colored wires the same length, about ½” to ¾” left exposed from the sheath.
  7. Insert rubber boot and RJ45 clip. Insert the rubber boot on both end of the cable.
  8. Then insert the wires into the RJ45 clip. Make sure each wire is fully inserted into the front of the clip.
  9. Crimp the RJ45 clip with Crimper tool.
  10. Make sure that the wires are ended up with right order and make good contact with metal parts in the RJ45 end.
  11. Finish the same process on both ends.
  12. Connect cable to the laptops. Connect the two computers together with the cable to the Ethernet card in your laptop.
  13. Configure the computers. To start the connection, you will have to assign IP address for both computers. To change the IP address you should make changes in both computers.
    • Open control panel from the start menu and click on ‘network and internet’ and click on ‘networking and sharing center’.
    • From the left side bar, click on ‘change adapter settings’.
    • Select the icon ‘Local area connection’ and right click on it, then choose properties.
    • From the Local Area Connection properties select Internet Protocol Version 4(TCP/IPv4) and click on properties button.
  14. Change IP address. Set the IP address on each laptop.
    • From the Internet Protocol Version 4(TCP/IPv4) properties select the option “use the following IP address”
    • Then
    • Laptop 1:
    •  IP address:
    •  Click on Subnet Mask space then it shows like:
    •  Default gateway:
    • Laptop 2:
    •  IP address:
    •  Click on Subnet Mask space then it shows like:
    •  Default gateway:
    • Then click OK.
  15. Change sharing settings. To share the information and resources we need to change some settings.
    • Select computer from the start menu and select properties of folder that you want to share by right clicking.
    • Then choose Share with -> Advanced sharing. Then select the button advanced sharing and choose the option share folder and select the name of folder. Then click OK.
  16. Now you can access shared files.


  • Users can access different computer peripherals, eg. printers, via the network (provided said peripherals are connected to the network as well).
  • Use color diagram of wires when attempting to arrange the wires. It will help to arrange in right order.
  • The crimping tool is a multipurpose tool; it can be used for both crimping and trimming of the wires.


  • End to End connection should not extend more than 100m. Try to keep cables short; the longer cable will affect the performance.
  • Avoid the sharing of folders and files that are contained important data and personal information.
  • The process of networking describe based on the windows 7 operating system. The process and steps will be varying according to the operating system.

Things You'll Need

  • Wire Cutters or Wire Strippers
  • RJ45 Data Plugs
  • RJ45 Cable Crimping Tool
  • An Ordinary Cat5, Cat5e, or Cat6 cable
  • Rubber boots
  • Two laptops(network card installed in both computers)
