Cabling comes in several varieties, including coax, twisted pair, and optical fiber. The most common types of cabling for smaller networks are coax and twisted pair. Coax cable resembles cable TV wire. If you have coax cabling installed and want to upgrade to a twisted pair cabling solution, look for networking products that support both technologies simultaneously. Twisted pair cabling resembles the wire that connects your telephone to the wall jack.
Fast ethernet is ideal for sending large, complex files such as databases and graphics.
Fast ethernet devices like hubs are typically less common and more expensive than ethernet devices. Twisted pair cabling also allows a combination of ethernet and fast ethernet in one network. The network operating system is required for every network. It allows computers and other connected devices descended receive information. Network operating system software can range from simple to robust.
