Cable television definition is - a system of television reception in which signals from distant stations are picked up by a master antenna and sent by cable to the individual receivers of paying subscribers —called also The smallest LAN may only use two computers, while larger LANs can accommodate thousands of computers. Cable operators have also experimented with video compression, digital transmission, and high-definition television (HDTV). It is a network bigger than Local Area Network (LAN), but territorially smaller than Wide Area Network (WAN), its diameter usually ranges from 5 to 50 kilometers. These are people who have had cable television all of their lives (not to mention Internet access, DVRs, DVDs, and so on for a shorter period of time).

Television in the United States: The growth of cable TV. Following figure shows few examples of addresses from both postal system and IP network. Wireless Local Area Network: A LAN based on Wi-Fi wireless network technology. A frequency-conversion device is connected to the television set of the subscriber to accommodate these signals of nonbroadcast frequencies. What is Scrambling in Digital Electronics ? In cable television, cables are used to transmit the broadcasting programmes to the television whereas antenna brings the transmitted programmes to the television set in Network TV. The connectivity can be either physical or virtual. The latter feature is offered by systems called videotex, which were first introduced in Great Britain and West Germany. If the cable line in is already installed in the home — for example, if you already have Internet service through the same provider — then under most circumstances you can install the TVservice yourself. The group of computers and devices are connected together by a switch, or stack of switches, using a private addressing scheme as defined by the TCP/IP protocol.

For example: Maybe for a home theater system you will hide the components in another room right behind the TV or in the basement right under the TV. It covers a large geographical area and may serve as an ISP (Internet Service Provider).
