Which protocol ensures that data will reach its destination and it will not be corrupted on its way?  STPTCPHTTPSMTP

Protocol Overview

The question refers to different protocols used in networking. Among the options provided—TCP, HTTPS, and SMTP—only one ensures that data reaches its destination reliably and without corruption.

Detailed Analysis of Each Protocol

1. TCP (Transmission Control Protocol):

   • TCP is designed to provide a reliable communication channel over an unreliable network. It ensures that all transmitted data packets are received by the destination and in the correct order. If packets are lost, TCP can retransmit them. It also includes mechanisms for error checking and correction.

2. HTTPS (Hypertext Transfer Protocol Secure):

   • HTTPS is an extension of HTTP that includes security features, primarily encryption through SSL/TLS. While it ensures that data is encrypted for security during transmission, it relies on TCP for the actual delivery of data. Thus, it does not inherently guarantee data integrity by itself.

3. SMTP (Simple Mail Transfer Protocol):

   • SMTP is a protocol for sending email messages between servers. It does not guarantee that the data sent will arrive intact or in order; it primarily focuses on email transmission and delivery.

4. UDP (User Datagram Protocol):

   • While not listed in the options, it is worth mentioning that UDP does not ensure reliable delivery, as it does not have built-in mechanisms for error checking or retransmission.

Conclusion

Among the options given, TCP is the protocol that guarantees data will reach its destination without corruption and in order. Therefore, the correct answer is:

Final Answer

TCP
