Difference between TCP and UDP with details

TCP and UDP is an important part of protocol system. You can get here the difference between TCP and UDP with examples details. Basically, TCP is called Transmission Control Protocol and UDP means User Datagram Protocol.

You may have listened of TCP and UDP when it’s setting a router or configuring farewell software. But, you don’t know that what are the differences between them? Now, see details about TCP VS UDP with examples

What is TCP?

TCP is known as Transmission Control Protocol. It is a connection-oriented protocol program that used to communicate over the internet. It’s provides error-checking and delivery of any types data. In fact, it is one of the best TCP/IP network protocol.

What is UDP?

UDP is known as User Datagram protocol. It is a cheap connectionless protocol that performs just such TCP network. It’s for checking error, and is not required delivery service. Continuously, UDP is a process that sends datagrams to the recipient whether they accept them.

Types of differentTCPUDP
DefinitionIt is a connection-oriented internet protocol. Actually, it means the communicating devices before transmitting data should establish a connection and close. is a cheap connectionless protocol that performs just such TCP network. It’s for checking error, and is not required delivery service. In fact, there is no overhead for starting a connection, and terminating a connection.
Full nameTransmission Control ProtocolUser Datagram Protocol or also it's called Universal Datagram Protocol.
ConnectivityTCP is an connection-orientedIt is a connection less control protocol.
FunctionIt's way across the internet as a message from one PC to another. based on connection. It is used in a message transport. This is not based connection that means one work or program can send a load of packets to other PC.
Header sizeIt is 20 bytesIt's 8 bytes
Data transfer speedIn fact, TCP is slower speed than UDPUDP is faster than TCP because, error recovery isn't attempted and it is best effort protocol.
Uses by other protocolsHTTPS, FTP, HTTP, SMTP, Telnet and etc.DHCP, DNS, SNMP, TFTP, RIP, and VOIP
Data PacketsTCP reorganizes data packets in the specified orderAs all packets are independent of each other UDP has no characteristic order. If ordering is required, it has to be managed by the layer.
Header fieldsDestination port, Check Sum and Source PortDestination port, Check Sum and Source Port that's same both.
AcknowledgementAcknowledgement segments of DataNo Acknowledgment of Data
HandshakeSYN-AcK, SYN, ACKNo handshake because, connectionless

TCP VS UDP Data Flow control

TCP does Flow Control and its required three packets to set up a connection, earlier any user data can be sent. TCP handles reliability.

On the other hand, UDP does not have a flow control system.

Data fields

TCP is accept that’s like

  1. AcK number
  2. Sequence Number
  3. Reserved
  4. Data offset
  5. Control bit
  6. Urgent Pointer
  7. Window
  8. Padding
  9. Options
  10. Source and
  11. Destination Port

UDP is required for

  1. Source port
  2. Destination port
  3. Length and
  4. Check Sum

Error Checking for TCP and UDP

TCP does testing error recovery and packets are re transmitted from the source.

UDP does testing error but, discards simply erroneous packets.

Usage of TCP and UDP

In fact, TCP is greatest to be used for applications that get high reliability where timing is less of an apprehension.

  • For World Wide Web (HTTP (Hyper Text Transfer Protocol), HTTPS (Hyper Text Transfer Protocol security)
  • File Transfer Protocol (FTP)
  • Secure Shell (SSH)
  • For Emailing (SMTP (Simple Mail Transfer Protocol), IMAP/POP(Internet Message Access Protocol/Point of Presence)

UDP is best suited for applications that need speed and efficiency.

  • Online video and Audio games
  • Live broadcasting
  • Trivial File Transfer Protocol (TFTP)
  • Domain Name System (DNS)
  • VPN tunneling
  • Streaming videos
  • Voice over Internet Protocol (VoIP)

Anyway, I think after getting this all everything about TCP and UDP you have cleared about the difference between TCP and UDP. Hope you are capable now to understand the difference. If you have any query then comment us.
