TCP vs UDP #technology #networking #education #shortsvideo #shorts #short

TCP and UDP are two core communication protocols used in networking, but they behave very differently depending on the use case.
TCP (Transmission Control Protocol) is a connection-oriented protocol. This means it establishes a reliable connection between sender and receiver before sending data. It ensures:
Data arrives in order
No data is lost or duplicated
Errors are checked and corrected
Because of this reliability, TCP is used in applications where accuracy matters, such as:
Web browsing (HTTP/HTTPS)
Email (SMTP, IMAP)
File transfers (FTP)
However, this reliability comes with more overhead and slower speed.
UDP (User Datagram Protocol) is a connectionless protocol. It sends data without establishing a connection and does not guarantee delivery, order, or error correction. It simply sends packets as fast as possible.
UDP is used in applications where speed is more important than reliability, such as:
Video streaming
Online gaming
VoIP (calls)
It has low latency and minimal overhead, but packets can be lost or arrive out of order.
In short:
TCP = Reliable, slower, ordered (secure delivery)
UDP = Fast, lightweight, no guarantee (real-time use) #technology #networking #education
