- A
telephone network is a connection oriented circuit switched network. This
means that a connection must be established between the two endpoints.
Bandwidth is reserved for this circuit.
The Internet is a connectionless packet
switched network. This means that packets can be sent without following an
established connection and bandwidth can be shared with other users.
- In a
telephone network, there is a dedicated connection established between the
two end users and it is a fixed line also the it has got a fixed monthly
rental for the connection but call charges are extra based on the duration
of the call and region(local or STD).
In case of Internet
there is no dedicated connection but the all authorized users are connected to
the network using a unique IP and the cost will be dependent on the data
downloads being made.
- Telephone
network can only give one to one connection only using a dedicated channel
in the network.
Internet can have
one-to-many connections through any channel which is free at that point of
time.
- In
case of Telephone networks the billing is done based on the duration of
the call and area of calling.
In case of internet
the billing will be mainly on the usage of the data in bits per second.
- The
telephone network will be able to connect to internet network using a dial
up connection and a dial up modem, but the data rate will be very low.
But in case of
internet the connection is made to the network using a broadband modem and
hence the data rate will be very high.
