Answer / fackrudheen

TCP/IP is a two-way communication between the client and
the server and it is a reliable and there is a confirmation
regarding reaching the message to the destination. It is
like a phone call.

UDP is a one-way communication only between the client and
the server and it is not a reliable and there is no
confirmation regarding reaching the message to the
destination. It is like a postal mail.

Answer / saranya

TCP/IP IS THE DELIVERY REPORT LIKR IN MOBILE PHONES. IT
GIVING US THE INFORMATION WHETHER OUR MESSAGE HAS RECIEVED
BY THE RECIPIENT OR NOT.
IP, GIVING ADDRESS WHERE THE PACKETS SHOULD GO...

Answer / phalak

tcp is connection-oriented and is responsible for end to
end delivery which seems to be reliable ,on the other hand
ip is responsible for logical addresing.

Answer / rajeev kumar

TCP/IP provide two-way data transmission in which TCP is
reaponsible for the data arrive complete and intact(perfect
form)or it check the error of data while UDP just send out
data packets
on the other hand IP contain the sddress of
sending station(where the packets is to be sent)
VOIP is used in telephone

Answer / joseph

Hi all,

TCP(Transmission control Protocol) so the rules and regulation s to be followed for(control of data transmission) packet delivery from one end to the other one(includes from when data shold be break how to build at other end).

IP(Internet Protocol) Rules and Regulations followed to deliver a packet to the destination.

Most of the time IP and the TCP works together cause IP knows where data to be delivered and TCP knows how to deliver.....

Answer / govardhan mattela

TCP
• connection based
• reliable
• byte stream
used in: FTP, telnet, http, SMTP
IP
point to point
m between machines
m addressed using IP address
message (packet) based
unreliable
m network failures
m router buffers fill up
dynamic routing
Þ order may be lost
heterogeneous intermediate networks
fragmentation

Answer / kumar gaurav singh

IP would handle datagram routing while TCP would be
responsible for high level functions like
segmentation,reassembly and error detection.

Answer / mohan kumar ,webstrange techno

TCP - Transmission Control Protocol

TCP is used for transmission of data from an application to the network.

TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.
IP - Internet Protocol

IP takes care of the communication with other computers.

IP is responsible for the sending and receiving data packets over the Internet.

Answer / prashant gupta

TCP & IP is both the protocol used for different pupose.
For internal comunication like printer TCP protocol is used
where as for Data transmission to another network like
EMails are the IP Protocol

Answer / manu g

TCP/IP is a protocol that create a connection between system
and transfer data to them. Internet Protocol(IP) is a
protocol that holed the address of systems. Internet
Protocol(IP) provide that address to TCP/IP to find out and
select the root.
TCP/IP is responsible for data transfer because it have
controls to transfer data.
