What is the main disadvantage of backwards compatibility?
  1. Older programs aren’t as good as new ones.
  2. Old programs may run, but they often run badly.
  3. Systems that are backwards compatible must be more complex.
  4. Old programs and new programs often have runtime conflicts.
Explanation
Answer: C - The main disadvantage is that systems that are backwards compatible are more complex. This generally makes them less stable and more vulnerable to attack from hackers. Windows strives for backwards compatibility, while Apple operating systems do to a lesser degree, and many Linux distributions do not attempt to be backwards compatible.
