TCP vs UDP

TCP vs UDP

Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) are the major protocols operating at Transport Layer. Transmission Control Protocol (TCP) and User Datagram Protocol (UDP) operate very differently and you can choose Transmission Control Protocol (TCP) or User Datagram Protocol (UDP) depending on your requirement.

TCP (transfer control protocol)	UDP (user data gram protocol)
Transmission Control Protocol (TCP) is a connection oriented protocol, which means the devices should open a connection before transmitting data and should close the connection gracefully after transmitting the data.	User Datagram Protocol (UDP) is Datagram oriented protocol with no overhead for opening, maintaining, and closing a connection.
Transmission Control Protocol (TCP) assure reliable delivery of data to the destination.	User Datagram Protocol (UDP) is efficient for broadcast/multicast transmission.
Transmission Control Protocol (TCP) protocol provides extensive error checking mechanisms such as flow control and acknowledgment of data.	User Datagram protocol (UDP) has only the basic error checking mechanism using checksums.
Sequencing of data is a feature of Transmission Control Protocol (TCP).	There is no sequencing of data in User Datagram protocol (UDP).
Delivery of data is guaranteed if you are using Transmission Control Protocol (TCP).	The delivery of data cannot be guaranteed in User Datagram protocol (UDP).
Transmission Control Protocol (TCP) is comparatively slow because of these extensive error checking mechanisms	User Datagram protocol (UDP) is faster, simpler and more efficient than TCP. However, User Datagram protocol (UDP) it is less robust then TCP
Multiplexing and De multiplexing is possible in Transmission Control Protocol (TCP) using TCP port numbers.	Multiplexing and De multiplexing is possible in User Datagram Protocol (UDP) using UDP port numbers.
Retransmission of lost packets is possible in Transmission Control Protocol (TCP).	8) There is no retransmission of lost packets in User Datagram Protocol (UDP).
