To establishing local area network(LAN) for the lab in windows systems.

A switch is used in a wired network to connect Ethernet cables from a number of devices together. The switch allows each device to talk to the others. Switches aren't used in networks with only wireless connections, since network devices such as routers and adapters communicate directly with one another, with nothing in between.

Follow the below steps to configure a lan:

Step 1 : Open my network places.

Step 2 : Right click on the "Local Area Connection " icon, click on properties.

Step 3 : Select internet protocol and click on properties.

Step 4 : Select “use the following IP address” option and fill the IP address.


        Ip Address : (your system IP)

	Subnet mask :

	Default Gateway : 192.168.*.* ( your preffered gateway )

	DNS server : server ip.

Note :  Ask these details to your service provider, if you dont know.

Step 5 : Fill the subnet mask ,default gateway and prefered DNS server.

Step 6 : To check the network connection, go to start, click on run and enter ping command followed other system's IP address. eg. ping (Your ip address that yu have configured)

Step 7 : You will see the command prompt with the following details.

              64 bytes from icmp_seq=2 ttl=128 time=0.668 ms

	      64 bytes from icmp_seq=3 ttl=128 time=0.704 ms
