Metropolitan Area Network: A network spanning a physical area larger than a LAN but smaller than a WAN, such as a city. This cable was used as the backbone-cable in the bus topology. One of the standards available for digital cable telephony, PacketCable, seems to be the most promising and able to work with the quality of service (QOS) demands of traditional analog plain old telephone service (POTS) service. Perhaps you already useing wireless networking in your local coffee shop, at the airport, or in hotel lobbies, and you want to set up a small office or home network. In Ethernet standards, this cable is documented as the 10base5 Thicknet cable. Digital television set-top boxes are used for satellite, cable, and terrestrial DTV services. Many large cable systems have upgraded or are upgrading their equipment to allow for bi-directional signals, thus allowing for greater upload speed and always-on convenience, though these upgrades are expensive. To connect two or more network devices are used the network cables. By the 1990s, tiers became common, with customers able to subscribe to different tiers to obtain different selections of additional channels above the basic selection. [Cable television headend. Cable television is an example of..... network. In Ethernet standards, this cable is documented as the 10base5 Thicknet cable. Ethernet cabling connects computers in wired networks, with the RJ45 Ethernet port resembling a standard … One problem with some cable systems is the older amplifiers placed along the cable routes are unidirectional thus in order to allow for uploading of data the customer would need to use an analog telephone modem to provide for the upstream connection. Network Diagram Example Modern homes usually have a network of interconnected devices of different kinds and with various types of connections and communication protocols. Broadcast networks and cable networks are both networks. But broadcast networks are more truly defined by that term, since they are a network of differently-owned and -operated stations networked together to achieve national reach. This evolved into today's many cable-only broadcasts of diverse programming, including cable-only produced television movies and miniseries.
