Which transport protocol is known for its higher overhead but guarantees transmission?

The Transmission Control Protocol (TCP) is known for its higher overhead and guarantees data transmission through various mechanisms. This protocol establishes a connection-oriented communication channel, which ensures that data is reliably transmitted between sender and receiver.

TCP achieves reliability through several key features:

1. Connection Establishment: TCP uses a three-way handshake process to establish a connection before any data transfer begins. This process ensures that both parties are ready for communication.

2. Error Checking and Correction: TCP provides error detection mechanisms through checksums. If an error is detected in the transmitted data, TCP will request the retransmission of the affected segments.

3. Sequencing: TCP assigns sequence numbers to data packets, allowing the receiver to reconstruct the data stream in the correct order even if packets arrive out of order.

4. Flow Control: TCP employs flow control techniques to ensure that the sender does not overwhelm the receiver with too much data at once.

5. Congestion Control: TCP monitors network congestion and adjusts its data transmission rate accordingly, helping maintain an optimal flow of data without causing network overload.

These features make TCP suitable for applications where data integrity and order are critical, such as web browsing, file transfers, and email. Thus, TCP
