ip number is a data transfer and without 
ip number not any handle data and  without 
tcp not transfer the data. and not reached 
the it data will not transffer .

tcp-6

There is no such port number of TCp/IP.
Port number is assigned to a specified protocol not to 
complete protocol suite.TCP/IP is a complete protocol 
package.Actully when the data is transferred from oone host 
to another hos it requires 3 types of address ...1st is the 
hardware or MAC ddress which is managed in data-link layer 
for the link of sorce and destnation segment.2nd is the ip 
address managed in network layer to identify the source and 
destination host.3rd is the socket address managed in 
transport layer....your question is related to socket 
address....Socket adddress is managed to link source 
application process to destintion application proicess.A 
socket address consists of a ip address +_port number.
Each protocol is assigned with a specified port 
number...through the port number the destination host can 
find which protocol is used to encapsulate ,encrypt and 
transfer the data.


The simple answer to ur question is that ....each protocol 
is identified on a network by its port number and served 
according to its port number not by its name.
