TCP and UDP are the way of transmitting data over the network. They have many similarities but there are also some difference between TCP and UDP which we will discuss later.
At the transport layer, there are two common protocol types. The user datagram protocol is udp, while the transmission control protocol is tcp. Connection-oriented and connectionless protocols, or dependable and unreliable protocols, are terms used to describe them.

What is Protocol?
In the networking world, a protocol is a set rule that every computer on a network follows. Protocol is useful for moving data from one place to another on a network.
TCP and UDP full form
The full form of TCP is Transmission Control Protocol and the full for of UDP is User Datagram Protocol.
What is TCP or TCP/IP Protocol?
TCP/IP stands for Transmission Control Protocol/Internet Protocol. This is the standard protocol model that a network uses.
TCP/IP model has the 5 layers which are as follow:
- Application Layer
- Data Link Layer
- Physical Layer
The TCP/IP takes care of number of bits sent and whether all the bits are received by the destination computer or not.
What is TCP? TCP protocols provide proper handshaking, we can say TCP protocols are reliable and connection-oriented. Because this ensures that data gets at the destination in the proper sequence.
The sequencing of each message shows that two devices are in constant contact. We can assumed it as a phone conversation in that both parties are always in communication.
What is UDP?
UDP transfers data in a connection less and unreliable manner. It does not check whether all the bits have reached the destination computer and may result in loss of data during transmission.
The best part of UDP is, even if some bits are lost, the image and audio file are composed with slight changes that will not disturb the original image or audio.
TCP Vs UDP | What is the main difference between tcp and udp?
In our digital world these protocols have their advantages and specific uses. Let’s see the tcp and udp difference.
|1.||It is a connection-oriented protocol.||It is a connection-less protocol.|
|2.||Data units of TCP are known as packets.||Data units of UDP are known as datagrams (It is also called packets).|
|3.||To establish a reliable connection, TCP uses a three-way handshake.||But UDP does not use a handshake process.|
|4.||TCP is slower than UDP.||It is simpler, faster, and more efficient than TCP.|
|5.||TCP does not support Broadcasting||UDP support Broadcasting|
|6.||TCP protocol is used by HTTPS, HTTP, SMTP, POP, FTP, etc||UDP protocol is used by Video conferencing, streaming, DNS, VoIP service etc|
|7.||It is reliable and it guarantees the delivery of data||It does not guarantee the delivery of data.|
