Procedure to create a network (LAN) using at least 6 computers.

First of all In order to connect a computer to an Ethernet cable, the computer must have an interface. In a desktop this is usually a Network Interface Card (NIC) or USB adapter. 

In a laptop, it is usually a PC card, a module that plugs into the laptop. The Ethernet jack may also be built into the laptop itself.

Procedure

1. Take the computer for which you are making server, insert the second LAN in that computer.
2. Connect your internet connection into the first LAN (inbuilt) on that computer.
3. Enter the IP address which you got from your ISP and check whether you can able to use internet on that system.
4. Now make sure that the second LAN is detected and is showing Unplugged.
5. Open properties of the first LAN (inbuilt LAN) and then go to "Advanced" option which is available on the top, then check both the boxes and say ok. and close everything.
6. Now take an Internet cable which is crimped on both the sides with same colors of wires.
7. Connect one end to the second LAN and the other end to the switch.
8. Now open your second LAN properties and go to the TCP/IP properties and there enter IP address as (192.168.0.1) or anything you wish Subnet Mask (255.255.255.0) and the gateway as (192.168.0.1).
9. Now open click on the switch and you will get a notification on your server saying that "Local Area Connection 2" is connected.
10. Now take an another Internet cable and one end of that cable should be in any one port of the Switch and the other should be in the second computer.
11. Now you will get a notification that you are connected to internet, open the LAN properties and enter the IP address as (192.168.0.2) subnet mask and gateway should be same as server. say ok
12. You will now be able to browse Internet on that particular system now.
13. Do the same with the rest of the systems.
14. And one more thing should be kept in mind that is you wont be able to browse internet Unless or Until your Server Pc is turned ON.

NOTE :- THE GATEWAY SHOULD BE SAME AS THE IP ADDRESS ONLY FOR THE SERVER.

NOTE :- THE IP ADDRESSES SHOULD NOT BE USED SAME FOR TWO SYSTEMS. SO BETTER GO WITH 192.168.0.1 (FOR SERVER) 192.168.0.2 (1ST CLIENT) 192.168.0.3(SECOND CLIENT) AND SO ON.......BUT THE SUBNET MASK AND GATEWAYS SHOULD BE SAME FOR ALL THE CLIENT AND SERVER SYSTEM.
