This article explains why you may want a home network and how to set one up.
What is a Local Area Network?
First of all, what is a local area network (LAN)? A network is simply two or more computers set up to communicate with each other. The Internet is a network of millions of computers. In your home, you can set up your computers to communicate with each other and that is a local or home network.
Why Would I Want a Home Network?
A network is useful for several reasons. The most common use is to share an Internet connection. One PC connects to the Internet and the other PCs in your home connect to that PC to access the Internet. Other reasons include the sharing of resources, such as a printer. One printer can be used by all of your PCs if they are joined by a network. You can also transfer files (useful for backing up data) or play head-to-head games with linked PCs.
What Do I Need to Build a LAN?
Each PC needs a Network Interface Card (aka NIC). Most PCs now come equiped with a NIC, however, you can purchase one for $10 to $20 and install it yourself. If you are connecting only two PCs, you can connect them directly with an ethernet crossover cable. Otherwise, you will need a hub, switch or a router (which acts as a sort of automatic switchboard) to connect two or more PCs together. You will need an ethernet cable to connect each PC to the hub or router.
How Do I Set-up the LAN?
You can use the Windows Network Configuration Wizard or you can configure it manually. Click on your operating system below for instructions specific to your PC. If you don't have the same operating system on each of your PCs, start with the PC with the most current operating system.
