Difference between TCP and UDP Protocol || TCP IP Model |

                        TCP VS UDP

#Summary - In today's video we will discuss about what is the key difference between TCP and UDP.

#TCP (Transmission Control Protocol) - TCP divides data into segments each having a sequence number. These sequence numbers are useful at the receiving end to rearrange the segments into original order.


* TCP is a connection oriented Protocol.
* TCP is a Reliable data Transfer Protocol.
*TCP has more payload
*TCP is slow as compared to UDP
* TCP sends data sequentially 
*Heavy Weight Protocol
*Flow Control
*TCP examples - SMTP, HTTP and FTP

#UDP (User Datagram Protocol) - UDP adds port addresses and error control information to the data and delivers the data.


*UDP is connection less Protocol
*UDP is a unreliable data transfer Protocol 
*UDP has less Payload
*UDP is a fast Protocol as compared to TCP
*UDP sends data Randomly
*Light Weight Protocol
*No option for flow control
*UDP examples - DNS, TFTP and VolP
