Error detection method used by the TCP/IP protocol is called __________.
- A.
Checksum
- B.
Error resolving
- C.
Debugging
- D.
Trobleshooting
Correct Answer
A. ChecksumExplanation
The error detection method used by the TCP/IP protocol is called checksum. This method involves calculating a numerical value based on the data being transmitted and appending it to the data. When the data is received, the receiver recalculates the checksum and compares it to the transmitted value. If they match, it indicates that the data was received without errors. If they don't match, it suggests that errors may have occurred during transmission. Therefore, the checksum is an important mechanism for ensuring data integrity in TCP/IP communication.Rate this question:
