How LAN Line works: A simple example

Let’s see a simple LAN(Local Area Network) works in which way. Let’s see this virtually. We use a network simulator which name is Cisco Packet Tracer. Cisco Packet Tracer is a powerful network simulation tool and you can do almost all networking simulation works in it. It has all the networking elements which is required to set up a network. You can found the download link of version 5.3.3 and 6.0.1 in this blog. Here I can mention that version 5.3.3 supports ip v 4 only and version 6.0.1 supports both ip v 4 and ip v 6.
Now let’s start a simple LAN connection. We’ll use this LAN connection.

First open Cisco Packet Tracer. Then draw the network in the way I have done. There are two switches. Use cross-over connection for switch to switch connection. And use straight through connection for switch and pc.

So we have set up our desired network. Now we have to give ip address to each pc. As switch has no functional port we need not give any ip address to switch. Let’s start with computer 1. Click the computer 1. You can see this type of picture.

Click on ip configuration. Here you can see the three place to give ip address, subnet mask and default gate way. Please be careful the information that in same network there is ip address and default gate way are same.
Let us our network address is
So for the each pc we’ll use the ip address as,,,
As it is a same network so subnet mask and default gate way be same for each pc. So let’s enjoy that.

After having successful ip implementation, let’s use message to examine if we have establish our network clearly or not. On the right sight of packet tracer you can see a close envelop, click there. You can see a close envelop in your mouse courser. Now with this message sign click the computer 4 then computer 3.

There is a status bar in the right low side. If the packet sent was successful then you can get the successful message as shown in the picture.

If you want to know how this work are doing in the network, then press shift+s. A new window will open, then click auto capture/play button.

That’s all for today. Enjoy
