What is error encoding?
  1. A form of copy protection that intentionally creates errors to prove authenticity
  2. Code that corrects errors that occur during routine operation
  3. Errors made when writing data to memory
  4. Mistakes made when writing a computer program
Explanation
Answer: A - Error encoding is a form of copy protection. Floppy disks used to be encoded with bad sectors that the program looked for before it would run. Copying floppy disks did not transfer the bad sectors, so the copied program could effectively determine that it was not original and would not run. Since floppies are no longer used, this tactic no longer works, but theoretically similar techniques that are in current use are often referred to as error encoding.
