WebThe table addressed by a hash function is known as a hash table.2If the hash function is chosen well, and the data are cooperative, the likelihood that two distinct keys will map to the same address is small. In the event that such collisions do occur, various methods are available to resolve them, at little added expense.

WebCRC24 Hash extends the basic CRC algorithm by using a polynomial function with a degree of 24. The polynomial function is used to generate a binary sequence that represents the input data. The binary sequence is then divided into equal-length chunks, and the CRC algorithm is applied to each chunk to generate a 24-bit output.
