This article on ‘What Is Checksum?’ will look into multiple steps involved in working the network checksum model. Click here to know more.

If the received checksum value matches the sent value, the transmission is considered to be successful and error-free. Advertisements A checksum may also be known as a hash sum. Techopedia Explains Checksum A mismatched checksum shows that the entire message has not been transmitted. TCP/IP ...

If the data packet is lost across the network, then the TCP will resend the lost packets. It provides a flow control mechanism using a sliding window protocol. It provides error detection by using checksum and error control by using Go Back or ARP protocol. It eliminates the congestion by ...
Error detection and correction in TCP is achieved through the use of three simple tools: checksum, acknowledgment, and time-out. Checksum: Each segment includes a checksum field which is used to check for a corrupted segment. ... Acknowledgment: ... ...
Error checking TCP performs error checking by using a checksum. When the data is corrected, then the data is retransmitted to the receiver. It does not perform any error checking, and also does not resend the lost data packets. Applications This protocol is mainly used where a secure and rel...
Window size TCP checksum– The sender generates a checksum and transmits it in every packet header. The receiving device can use the checksum to check for errors in the received header and payload. Urgent pointer– If URG control flag is set, this value indicates an offset from the sequence...
Error-checking mechanisms.TCP provides extensive error-detection procedures, such as determining the connection timeout period, providing a checksum field, and receiving and sending acknowledgments. On the other hand, UDP only performs basic problem-checking using checksums. ...
