What is the Difference between TCP and UDP

TCP/IP:

TCP/IP stands for Transmission Control Protocol and Internet Protocol. In TCP/IP, IP deal with the packets only while TCP establishes a connection between 2 hosts and responsible for data transfer.

Difference Between TCP and UDP:

TCP and UDP work on Transport Layer (Layer-4). Both transmitting data from one host to another host-

	TCP	UDP
Stand For	Transmission Control Protocol	User Datagram Protocol
Connection	Connection-Oriented Protocol	Connection-Less Protocol
Reliability and Acknowledgement	More Reliable and ACK with 3 way-handshake	Unreliable and No ACK
Data Transfer	Slower than UDP	UDP is faster because there is no error checking
Header Size	20 Bytes	8 Bytes
Error Checking	Yes	No
Flow Control	Yes	No
Handshake	SYN, SYN-Ack, ACK	No Handshake
Use by protocols	Http, Https, FTP, telnet,	DNS, DHCP, TFTP, SNMP, RIP, VoIP

 

Connection Oriented– This is giving guarantee for error free and sequencing and flow.

Connection Less– This is not giving error-free data guarantee.
