    TCP is a connection-oriented protocol that provides reliable, ordered delivery of streams of data. It uses acknowledgments and packet retransmission to ensure reliability. TCP connections require a three-way handshake and provide congestion and flow control. UDP is a connectionless protocol that does not provide ordering or reliability, making it faster but also less secure than TCP. It is commonly used for applications like gaming where speed is prioritized over reliability.
