FTP; HTTP; DNS (uses both TCP and UDP); several e-mail protocols including POP3, SMTP, IMAP4.
Transmission Control Protocol, or TCP, is one of the main protocols of the internet Protocol. Three network applications that use TCP are HTTP, HTTPS and SMTP.
TCP is used to ensure a reliable communication over a network that is basically unreliable. It is used by many higher-level protocols, including FTP, TFTP, POP3, SMTP, HTTP, and many others.

SCTP is a protocol that has the ability to deliver functionality that is similar to TCP. Like TCP, an SCTP session can be configured to offer ordered, guaranteed, delivery with congestion control and a notion of a session. It differs in that it offers other features and has an implementation that is not directly compatible with TCP; both peers' network stacks and applications will also need to support SCTP.
Data travels in packets. In a TCP connection, every packet must reach the destination before the transmission will be complete. This means that it goes back to resend packets should any be dropped. UDP does not do this. This makes it ideal for real time applications that cannot viably stop. These include VoIP and video streaming. [Above answer is right, UDP is used in the situations where partial or little data loss is bearable such as VoIP, Video Streaming, you might have experienced it many times when browsing youtube videos. Many of peer to peer applications use this service. It doesn't guarantee the loss-free transmission of data, as TCP does. It does use to provide the current user facility to push as much data as he can on the link, without caring about others. Most of today's applications which used to use UDP has now been transferring to TCP. A good example of it is bit-torrent ]
