The standard cable used in the U.S. is RG-6, which has a 75 ohm impedance, and connects with a type F connector. 1 Press the MENU button. Network Diagram Example Modern homes usually have a network of interconnected devices of different kinds and with various types of connections and communication protocols. In the most common system, multiple television channels (as many as 500, although this varies depending on the provider's available channel capacity) are distributed to subscriber residences through a coaxial cable, which comes from a trunkline supported on utility poles originating at the cable company's local distribution facility, called the "headend". Traditional cable television providers and traditional telecommunication companies increasingly compete in providing voice, video and data services to residences. The combination of television, telephone and Internet access is commonly called "triple play", regardless of whether CATV or telcos offer it.

A bus network topology relies on a common foundation (which may take the form of a main cable or backbone for the system) to connect all devices on the network. By giving each channel a different frequency "slot" on the cable, the separate television signals do not interfere with each other. During the 1990s, the pressure to accommodate the growing array of offerings resulted in digital transmission that made more efficient use of the VHF signal capacity; fibre optics was common to carry signals into areas near the home, where coax could carry higher frequencies over the short remaining distance. Additional local channels, such as local broadcast television stations, educational channels from local colleges, and community access channels devoted to local governments (PEG channels) are usually included on the cable service. Typically, a LAN encompasses computers and peripherals connected to a server within a distinct geographic area such as an office or a commercial establishment. Public Network A cafe creates a public wifi network that allows customers to connect to the internet. This main cable or bus forms a common medium of communication which any device may tap into or attach itself to via an interface connector.

The fiber trunkline goes to several distribution hubs, from which multiple fibers fan out to carry the signal to boxes called optical nodes in local communities. When the broadcast failed in regions where the reception of signals was limited, large community antennas were built and cables were run from it to the houses. not scrambled as standard TV sets of the period could not pick up the signal nor could the average consumer `de-tune' the normal stations to be able to receive it. a)Metropolitan Area b)Campus Area c)Wide Area 2 See answers priyadarshianuj78 priyadarshianuj78 Answer: Metropolitan Area Network.

Many home network layouts work fine, but most are variations on a basic set of common designs. FM radio programming, high-speed Internet, telephone services, and similar non-television services may also be provided through these cables. Most systems use hybrid fiber-coaxial (HFC) distribution; this means the trunklines that carry the signal from the headend to local neighborhoods are optical fiber to provide greater bandwidth and also extra capacity for future expansion. The early systems simply received weak (broadcast) channels, amplified them, and sent them over unshielded wires to the subscribers, limited to a community or to adjacent communities. Rarely, as in the college town of Alfred, New York, U.S. cable systems retransmitted Canadian channels. (There were frequency gaps between 4 and 5, and between 6 and 7, which allowed both to be used in the same city). Broadband internet access is achieved over coaxial cable by using cable modems to convert the network data into a type of digital signal that can be transferred over coaxial cable.
