  • Reliability: TCP prioritizes reliable delivery. It checks for errors and retransmits missing packets. This makes it ideal for important data like emails or file transfers. UDP prioritizes speed over reliability. It sends data packets without error checking and doesn't resend lost ones. This is suitable for real-time applications like live streaming where a slight delay is acceptable.
  • Data Transport: TCP guarantees in-order delivery. Packets might arrive rearranged during transfer, but TCP reassembles them correctly. UDP sends data packets independently, making it faster but potentially out of order on arrival.
In essence, TCP offers a secure, reliable mail service, while UDP is a faster but riskier fire-and-forget method.

TCP vs. UDP: Connection Management and Data Delivery

TCP and UDP, both workhorses of the internet, handle data transfer differently:

  • Opening a Connection: TCP establishes a connection before data transfer. It's like making a handshake agreement. This ensures a reliable channel is available. UDP skips this step, sending data like throwing a message in a bottle - faster, but with no guarantee of delivery.
  • Closing a Connection: TCP gracefully closes the connection after data transfer, ensuring all information arrives. UDP simply stops sending data without a formal goodbye.
