WebApr 6, 2001 · A checksum is determined in one of two ways. Let's say the checksum of a packet is 1 byte long. A byte is made up of 8 bits, and each bit can be in one of two states, leading to a total of 256 (2 8) possible combinations. Since the first combination equals zero, a byte can have a maximum value of 255. WebThe resulting checksum is 210. You can use the calculator above to check this result. In this example we have used a one byte long checksum which gives us 256 different values. Using a two byte checksum will result in 65,536 possible different checksum values and when a four byte value is used there are more than four billion possible values.
