LOCAL AREA NETWORK (LAN)

With this connection we can share document, internet connection, printer and every facilities that the computer system has. Many advantages we can get with this LAN. We dont have to buy many printer, only one printer for all computer we have. we only need one internet connection for all computer we have. we can communicate with other computer with this system. 

For computer network installation, please dont use unqualified supplier. Because this computer network is very sensitive to other cable installation such as power cable. it need special cable that can protect the data transmission from power cable electromagnetic field. The cable must use is Shielded Twisted Pair (STP) Cat 5. Why it must be Twisted? cause the twisted pair strenghten the data signal. for normal use we can use Un Twisted Pair (UTP) Cat 5. Why it must be CAT 5? cause the copper contains of each cable is different. for Cat 5 copper contains almost 95%. and data is a very low voltage. The bigger copper contain the better transmission.
