INTRODUCTION
 Internet is a networks of network(Global
  n/w)
 A cable modem connects to a PC using
  the same coaxial cable that brings all
  channels to your television.

   India has a cable penetration of 80 million
    homes, offering a vast network for control
    the internet access.
How access the Internet using the
Cable Network

   Use the dial-up telephone services
    provided by your Cable Company in
    conjunction with a modem.

   To use a Cable modem.
Cable Modem
   A "Cable Modem" is a device that allows
    high-speed access to the Internet via a
    cable TV (CATV) network.

   The cable modem attaches to computer
    through an Ethernet Network Interface
    Card.

   It takes a signal from the computer and
    converts it for transmission over the cable
    network.
How does it connect
   Ethernet 10BaseT is emerging as the most
    predominant method.
How Cable Modem Is Work
   Your Cable Company supplies you with a
    connection to your home which in turn is
    connected to a splitter box.

   One spur from the splitter box is connected to
    your TV through a TV Adapter, the other being
    connected to your Cable Modem, which in turn
    is connected to your computer through an
    Ethernet connection.

   Cable modems can be part modem, part tuner,
    part encryption / decryption device, part bridge,
    part router, part NIC card and part Ethernet
    hub.
Splitter Box and TV Adapter
   Hybrid Adapter :-
Support For Multiple PCs
   A Cable Modem can provide the
    Internet access to multiple PCs, if they
    are connected via LAN.

   Using Ethernet hub or Router.
Advantages
 High-Speed Internet Access
 High Availability
 High bandwidth to low cost
 No new software is required
 Always on Connectivity
 No reconstruction of cable system is
  required
Limitations
 Traffic congestion on the net
 Higher security risk than dialup
  connections
 Always on Connectivity
 Usually tied with cable TV subscription
Conclusion

   Cable TV has a strong reach to the homes and
    therefore offering the Internet through cable be
    a scope for furthering the growth of internet
    usage in the homes.

   In future this technology will implemented
    by india.
