TCP (Transmission Control Protocol) and UDP (User Datagram Protocol) are core Internet protocols, but they serve different purposes. TCP is connection-oriented, ensuring reliable and ordered delivery of data through error checking and confirmation receipts. It’s perfect for applications like web browsing and email, where data integrity is crucial.
On the other hand, UDP is connectionless, offering a faster but less reliable service. It doesn’t verify whether data is received, making it suitable for applications like live streaming and online gaming, where speed is prioritised over perfect data transmission.
