TCP and UDP both are used in networking or packages online. They’re the standards to deliver the data. Both perform the exact same work but the way differs. TCP means “Transmission Control Protocol”. UDP stands for “User Datagram Protocol.” The main difference between them is the fact that the TCP is connection oriented while UDP is link-less mean wireless. Here in this article, we are going to share the basic Difference Between TCP and UDP.
You’ve probably seen references to TCP and UDP when establishing port forwarding on the router or when configuring firewall software. Those two methods are utilized for different types of data. TCP/IP can be a selection of protocols used by devices to communicate over the Internet & most local communities. It’s named after two of it’s original protocols—the Transmission Control Protocol (TCP) as well as the Internet Protocol (IP).
Difference Between TCP and UDP
TCP: TCP means Transmission Control Protocol, reliable and safe but comparatively slower since it keeps the data clean and checks error.
UDP: UDP means User Datagram Protocol, less reliable but is faster in data moving than TCP.
TCP (Transmission Control Protocol) is connection-oriented protocol whereas UDP (User Datagram Protocol) is connectionless protocol.
TCP vs. UDP
TCP: TCP (Transmission Control Protocol) is type of Internet Protocol (IP) traffic. It is connection oriented protocol which means that devices must have established a connection before transferring data and connection must be closed after transmitting data. It offers error checking mechanisms that include flow control and data acknowledgement. It assures data packets’ delivery. Selection of protocol completely depends upon your application’s requirements.
UDP: UDP (User Datagram Protocol) is also one of the types of Internet Protocol (IP) traffic. UDP is connectionless protocol. It does not require any connection to establish a connection for transmission of data. It offers basic error checking mechanisms that are why it has fast speed. The integrity is assured only on the single datagram. UDP is used when you need broadcast packet transmission. For the transmission of video or audio UDP would be the best choice.
|TCP is connection-oriented protocol||UDP is connectionless protocol. There may be corruption while transferring a message.|
|You don’t have to worry about data arriving in the wrong order.||Yyou don’t know what order they’ll arrive in i.e. no ordered|
|There may be multiple packets per read call.||One packet per one read call.|
|World Wide Web (Apache TCP port 80), e-mail||Domain Name System (DNS UDP port 53), Trivial File Transfer Protocol (TFTP)|
Following are the basic differences between TCP and UDP:
- TCP is connection oriented, but UDP is connectionless.
- TCP requires more processing as compared to UDP at network interface level.
- TCP offers extensive error checking mechanisms.
- TCP has slow speed due to extensive error checking mechanisms whereas UDP provides fast speed.
