No TCP a reliable protocol whereas UDP is unreliable.
TCP and UDP are transport layer protocols; the OSI layer is layer 4 (transport)
DNS does.
FTP uses TCP.Usage of Transport Layer protocol (tcp or udp) depends upon various applications.Such as FTP uses TCP, TFTP uses UDP.
Server Message Block (SMB)( Explanation ) When NetBIOS is disabled, SMB runs over TCP/445. Kerberos runs on TCP/User Datagram Protocol (UDP)/88. RPC runs on TCP/135. HTTPS runs on TCP/443.
TCP
Yes, it does.
UDP is alot faster than TCP. So if its realtime obviously it has to be fast, thus UDP. The only problem is UDP isn't as reliable or as secure as TCP. But it does have the speed advantage.
UDP does not require as much resources as TCP but in the same time, it does not insure delivery of packets.
UDP
No it uses UDP packets.
UDP and TCP both are transport layer protocols. UDP is connection less and TCP is connection oriented. UDP is preferred over TCP when large amount data is to be sent like on skype or video conferencing .
DNS uses both TCP and UDP, also a lot of online chats use UDP. I think even when you want videos on YouTube UDP is used to deliver video and audio.
You can use either TCP or UDP. If you need reliable connection use TCP otherwise UDP.
TCP and UDP are two different layer 4 protocols. TCP reliably sends data with acknowledgments and UDP sends data without checking if the destination received it. Skype uses UDP while email uses TCP.
