Generally Ethernet switch and router are required to connect multiple computers but it cost should be approx Rs 1,200 to Rs 1,500, and it only make sense if you want connect more than two computer. If you want to connect only two computers to each other, you may use a simple cross over cat5 cable and for this you will need to spend only approx Rs 100 only. Here we show you how to connect two computers by using a simple cross over Ethernet cable.

First of all you, you have required a crossover Ethernet cable to connect two computers but if you don’t have cross over cable no need to worry about it. We can make a new crossover cable; the basic requirement for making a cross over cable is minimum two RJ45 connector, Crimping tool and Ethernet cable. The length of the cable depends on the distance between both computers.

Making a Cross cable

Cut the required length of cat 5 cable, peel out the cable and separate four pair, now straighten all the pair, connect all the wire as shown in following picture.

As shown in picture first connector’s PIN-1, PIN-2, PIN-3 andPIN-6 will be connected with the second connector’s PIN-3, PIN-6, PIN-1, and PIN-2 respectively and rest pins will remain unchanged.

Now insert the wire in RJ45 connector with carefully and gently crimp it with the crimping tools. Same process applies at the both end.

Insert the wire carefully in RJ45 connector in the following manner-WHITE GREEN- GREEN-WHITE ORANGE-BLUE-WHITE BLUE-ORANGE-WHITE BROWN-BROWN.

Insert the wire carefully in RJ45 connector.

At the other end same process will be apply, but the only diffrence now wiil be the order of the cable colors. Follow the order of the color as WHITE ORANGE-ORANGE- WHITE GREEN- BLUE-WHITE BLUE- GREEN-WHITE BROWN-BROWN.

Networking the computer

In order to network two computer few settings need to be altered in each computer ‘s netwok card properties section.

First of all asign a unique name and similar work group name of each computer. To change the computer name and work group you will need follow the some steps.

Step-1. Right click onthe my computer icon and click on properties.

Step-2 Select the computer name tab(in windows vista and windows 7 click on the advance settings) and then click on the “change button”

Step-3 Enter the unique name of the both computers and similar work group. Click on the apply button and your will prompt you for restart the system yoy may choose the restart later.

Step-4  Now open the network section.

1.   For windows Xp Click on the start button >> Setting >> Network Connection.
2.       For windows Xp Cick onthe start button >> Control Pnael >> Network and Internet >>Network Connection  and right click on the Ethernet card.
3.  Select properties and double click on the internet protocol. Now click “use the following IP adress” and enter a unique Ip address for example 192.168.0.3 for first computer  and 192.168.0.4 for second computer and subnet mask “255.255.255.0” and leave blank DNS and Gateway field.
4.  Click on the OK button twice and hence your computers are networked.

Now you may share some file,folder or drive in both computer in order to change data.

And now your computers are ready to use.
