A home network is a residential local area network connecting multiple devices within the home. The simplest home networks connect two or more microcomputers that share files, a printer, and a single Internet connection. Connecting a server adds functionality.
Some companies such as AT&T offer their version of home networking to furnish data, video, and voice services to residential customers. These services usually operate over the existing home wiring. The companies install and manage the network, all at a price.
While this article presents some of the software found in home networks we also consider the hardware components. Essential home networking components include a high-speed modem for connection to the Internet. Connection choices include a DSL modem for telephone subscribers and a cable modem for cable subscribers. If you choose an old-fashioned traditional modem, the service could be excruciatingly slow. If you want to connect several computers to the Internet simultaneously you’ll need a router, which may be wireless. Other components include a wide variety of toys such as digital audio players, games machines, and TiVo. You may also consider a print server and for large networks, a network attached storage (NAS) device.
When your home network gets complicated you may consider designating one computer as a home server that handles account authentication, backup, file, printer, and program serving, media center serving, web serving, and more. Interestingly enough the server need not be the most powerful computer in your network. It should have a fast hard drive. An uninterruptible power supply is highly recommended. » Read more: What You Need to Know About Popular Software – Home Networking Software
