Which type of network protocol ensures error-free transmission of data over a network?

The transmission of data over a network can be subject to various types of errors, such as lost packets or corrupted data. The Transmission Control Protocol (TCP) is designed to provide reliable, ordered, and error-checked delivery of a stream of data between applications. It achieves this through several mechanisms:

1. Error Detection: TCP uses checksums for error detection, allowing the receiver to verify the integrity of the data received. If an error is detected in a segment, TCP can discard the segment.

2. Retransmission: If a segment is lost or an error is detected, TCP will request the retransmission of that segment, ensuring that all data is received correctly and in the correct order.

3. Ordered Delivery: TCP maintains the order of packets, so even if packets arrive out of order, they will be reassembled in the correct sequence at the receiving end.

These features together ensure that data is transmitted accurately and reliably, making TCP the go-to protocol for applications where the correctness of the data is crucial, such as web browsing, email, and file transfers.

In contrast, User Datagram Protocol (UDP) does not include these error-checking and retransmission capabilities, making it faster but less reliable. HTTP
