hi,

  1. TCP(Transmission Control Protocol). TCP is a connection-oriented protocol, a connection can be made from client to server, and from then on any data can be sent along that connection.
    • Reliable - when you send a message along a TCP socket, you know it will get there unless the connection fails completely. If it gets lost along the way, the server will re-request the lost part. This means complete integrity, things don't get corrupted.
    • Ordered - if you send two messages along a connection, one after the other, you know the first message will get there first. You don't have to worry about data arriving in the wrong order.
    • Heavyweight - when the low level parts of the TCP "stream" arrive in the wrong order, resend requests have to be sent, and all the out of sequence parts have to be put back together, so requires a bit of work to piece together.

  2. UDP(User Datagram Protocol). A simpler message-based connectionless protocol. With UDP you send messages(packets) across the network in chunks.
    • Unreliable - When you send a message, you don't know if it'll get there, it could get lost on the way.
    • Not ordered - If you send two messages out, you don't know what order they'll arrive in.
    • Lightweight - No ordering of messages, no tracking connections, etc. It's just fire and forget! This means it's a lot quicker, and the network card / OS have to do very little work to translate the data back from the packets.

TCP is connection oriented UDP connectionless

TCP creates virtual cicrute between sending and recieving divece

TCP sagments are numbered and sequnced though in recieving divice can place them in the same number

TCP uses ack but UDP not

TCP is a connection oriented protocol found at layer 4 (Transport) layer of the OSI (Open Systems Interconnect) model. TCP is windowing, where the sliding window allows a varying amount of data bits to be transferred to a destination at a time. UDP is a connectionless protocol also found at layer 4 of the OSI model, unlike TCP, there is no sychronisation of transmitting/recieving devices before data is sent- therefore UDP is considered less reliable than TCP.

Well TCP/IP is not a protocol but a protocol stack containg 4 layers. At the 3rd layer ie. transport layer exist TCP protocol or UDP protocol depending upon the application you are using. Exmple if you are using FTP then it uses TCP at Transport layer and if you are using SNMP it uses UDP at Transport layer. The difference between TCP and UDP are mentioned in the above replies like TCP :- connection oriented, reliable nad UDP connectionless, unreliable.

So it is the need of application which decides which protocol to use at transport layer.

TCP/IP is a connection oriented protocol layer whereas UDP is connectionless protocol.

TCP/IP is little bit slow but it is secure where as UDP is very fast but it is not secure.

TCP/IP is a set of connection oriented protocols used to manage data transmission by breaking it upto packets so it is more reliable and slow processing but UDP is connectionless protocol which isnot realible but faster processing.

TCP/IPis a protocol suite . which is similar to a OSI layer which has 5 layers . in which the top 3 layer of OSI i.e application , presentatio and session is combined to gether in TCP/IP as application layer and we have transport,network,datalink and presentation layers . In TCP/IP each layer is indepent of its functions.

whereas UDP is a communication protocol used in transport layer for connectionless,unreliable transmission of datas.

tcp is an  example of connection oreinted  technology where u get an acknowledgement   best example is sms to sms using  mobile phone where u get and acknowledgement.


udp and ip are connection less technology where u dont get an acknowledgement.

TCP is reliable and any data sent, automatically receives an acknowledgment. But UDP does not give acknowledgment.

That is the big difference TCP and UDP

TCP - Transfer Control Protocol.
a.Reliable
b.Connection oriented.
c.Acknowledgement

UDP - User Datagram Protocol.
a.Non Reliable
b.Connectionless
c.No Acknowledgement

TCP is connection oriented protocol of the transport layer
of OSI model,
UDP is connectionless protocol of the transport layer of the
OSI model
TCP is reliable
UDP is nonreliable
TCP uses three way handshake to establish, connection to
other host
no such three way handshake taken by UDP

  Transmission Control Protocol (TCP) User Datagram Protocol (UDP)
1 TCP is a connection oriented protocol. UDP is connectionless protocol.
2 TCP ensures reliable data communication but gives slow throughput. UDP is unreliable but gives fast throughput.
3 TCP supports Virtual Circuits. UDP doesn't supports Virtual Circuits.
4 TCP uses sequencing, acknowledge, error detection, error recovery and  flow control (windowing). UDP doesn't.
