 Internet is a networks of network(Global n/w)

 Internet data can be transferred through Cable networks
wired to the user computer.

 Accessing the Internet at 10 megabits per second.

 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.

3

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

 To use a Cable modem.

4

 A Cable modem is a device at the subscriber end of a cable that
allows a computer to be connected to the Internet through an
existing Cable network connection.

 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.

 A Cable Modem sends and receives data to and from the
Internet by using the existing coaxial cable network.

5

 It takes a signal from the computer and converts it for
transmission over the cable network.

 The modem translates cable signals the same way a
telephone modem translates signals from a telephone line.

6

 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,
the other being connected to your Cable Modem, which in
turn is connected to your computer through an Ethernet
connection.

10

 A cable modem is theoretically capable of receiving
data at 30Mbps to 40Mbps which, if it were achieved
in the real world, would be 892 times the throughput
of a standard 56k modem.

13

 The theoretical performance of a Cable Modem is
based upon all other devices being able to work at the
same speed and performance as the Cable Modem.

 However, in a similar way that the actual usable
bandwidth on a 10Mbps Ethernet connection reduces
to a 4Mbps, so too will the performance of a Cable
Modem connection be reduced.

14

 Although performance to services on the cable
network itself can be amazingly fast, access to 'the
outside world will be slowed down by the performance
of other connections on the way.
 As usage on your segment grows ( as more customers
are added ) bandwidth must be shared by more
people.

15

 A Cable Modem can provide the Internet access to
multiple PCs, if they are connected over LAN.

 Using Ethernet hub or Router.

18

 Advanced High-Speed Internet Access
 High bandwidth to low cost
 No new software is required
 Convenient – You are always connected to the Internet
 No reconstruction of cable system is required
 Does not affect your phone line.
 Unlike ADSL, its performance doesn’t depend on distance
from the cable office.

20

 Bandwidth is shared over the same cable line. Hence
connection speed is affected by the number of people using
the internet at the same time in your neighborhood.

 Less secure (personal firewall is needed).

 Always on Connectivity

21

 Cable Internet access is the principal competitor to DSL
and is offered at a range of prices and speeds overlapping
that of DSL.

 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.

 Access of Internet via cable television network offers very
high speed without traffic jam and with less cost.
