Simple LAN Computer Network

When my friend at home has more than one computer, and each computer you want to connect with each other woods in order to share data, printers, internet connection sharing, etc., we could do with making a computer network LAN (Local Area Network) is simple ..
If the last post used wireless adhoc connection, in this post we use the wired connection using a data cable UTP (unshielded twisted pair), which is the standard cable for LAN network connection.Computers are used today are already equipped with a LAN card or also known as NIC (Network Interface Controller), or Ethernet Card.




• If the number of computers that will connect only two pieces, we just simply providing a single UTP cable length according to the distance between the computers on either end of the cable has been fitted with an RJ-45 (standard connector for wired LAN UTP) configuration with Cross / cross.

• If the number of computers that will connect more than 2 pieces, then we need to add a tool called Switch or Hub. At the current price of a switch to standard housing is very affordable.Of each - each computer connected to the switch using UTP cable with RJ-45 connectors at both ends with a configuration Straight / straight.

• Installation of connectors on UTP cable can be made, but to ease margin, just go to the computer store that also provides network equipment, and just say to buy all pair UTP cable connector configuration with cross / cross to connect the computer to a computer (two computers ), or straight / straight for connection of more than 2 computers / using a switch.



Configure an IP address (Internet Protocol TCP / IP)To be able to communicate with each other, respectively - each computer must be alamai IP
• Go to Network Connections (Start -> Control Panel -> Network Connection)• Select / double-click Local Area Connection• Double click on the Internet Protocol (TCP / IP)• Click Use the following IP address and fill in the IP address and subnet maskFor example,komputer1 IP Address: 192.168.0.1komputer2 IP Address: 192.168.0.2komputer3 IP Address: 192.168.0.3komputer4 IP Address: 192.168.0.4etc. ..Subnet Mask must be the same: 255.255.255.0


To determine the success or failure of the connection did the ping command from one computer to another computerExamples of komputer1 to komputer2:• In Komputer1: Click Start -> Click Run -> type CMD -> click OK, it will show the Command Prompt• Type in ping 192.168.0.2 press enterReply from komputer2 there must• Perform the same command to find a connection to another computer.
