• TCP is a connection oriented Protocol and is suited for applications which use high reliability and where transmission time is relatively less critical for applications than that use UDP.

  • Where as UDP needs applications that need fast,efficient transmission such as games.

  • Its feature of handling small queries from huge number of clients is useful for servers.Hence this is the reason why TCP is the most commonly used application protocol for HTTP,FTP,SMTP,IMAP,POP3.

  • Also Because TCP is more reliable, and HTTP, FTP, SMTP, and POP3cannot be affordable using UDP while UDP cannot transmit packet and guarantee a well order delivery.

  • TCP is a connected-oriented network so packet will be delivered to the destination.
