difference between Tcp and udp

Answer Posted / jyotish kumar naik

TCP connection

1- Reliable
2- Reliable because connect() present at the client side.
3- TCP work on data stream
4- 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.

5-heavy n/w overhead
6- Three way handshake is performed.
7- Acknowledgement facility

UDP connection
--------------
1- Not reliable
2- Not reliable because connect() is not present at client
side.
3- UDP work on data block
4- Not ordered - If you send two messages out you don't
know what order they'll arrive in.
5-Low n/w overhead
6- No three way hand shaking
7- No acknowledgement facility
