TCP vs UDP Difference- Table Form – Tabular Form – Distinguish Between


Here’s a quick difference between the two protocols:

Full form  

Transmission Control Protocol


User Datagram Protocols
2 Order: The destination will receive the packets in the same order it was being sent. There will be no proper order/ arrangement of data.
3 Success Rate: Data must be transmitted WITHOUT FAIL No guarantee that all data will be successfully transmitted. It is used where it is acceptable to lose some data points.
4 Protection: TCP guarantees. UDP provides no guarantee for delivery and no protection from duplication.
5 Overhead: More overhead due to error-checking mechanisms. The simplicity of UDP reduces overhead from the protocol and can be adequate for some applications.
6 Speed: Slower Faster
7 Connection: Connection-based protocol

Connection is first established with recipient, only after that sent.

Connection-less Protocol

A computer may send UDP packets without first establishing a connection to a recipient.

8 Real Time Example: TCP is mailing a letter with a return receipt at the post office, except that the post master will organise the letters in-order-of mailing and only deliver them in-order. UDP is mailing a letter at the post office without making extra care if all mails are received.
9 Usage: Web, SSH, FTP, telnet, IMAP/POP, receiving mail, DNS, DHCP, Media streaming, Tunneling/VPN
10 In short: TCP is for high-reliability data transmissions UDP is for low-overhead transmissions
