The simplest checksum algorithm is the so-called longitudinal parity check, which breaks the data into "words" with a fixed number n of bits, and then computes the exclusive or (XOR) of all those words. The result is appended to the message as an extra word. In simpler terms, this means adding a bit to the end of the word to guarantee that there is an even number of '1's. To check the integrity of a message, the receiver computes the exclusive or of all its words, including the che… Web这样做，我无意中发现了以下信息： Header checksum: 0x0000 [incorrect, should be 0xac15 (may be caused by "IP checksum offload"?)] 这条消息的原因是什么 还有什么后果吗 我很 … microchip material crossword https://mmservices-consulting.com
