About 4-Bit Checksums

A 4-bit checksum is a simple error detection mechanism that works by:

  1. Adding all the values
  2. Taking only the 4 least significant bits (using modulo 16)
  3. Performing a ones' complement (flipping all bits from 0 to 1 and vice versa)

The checksum can be used to verify data integrity. If all data (including the checksum) is added together, it should result in all 1s if the data is error-free.
