Q

ENUMERATE: Limitations of Computers

A
  1. The computer functions only when input and the necessary
    instructions to process the information have been provided
    by a human being.
  2. It can detect but generally cannot correct inaccurate entry
    by itself.
  3. It is subject to occasional breakdown or computer
    malfunction because of power failures, computer failure,
    humidity, temperature and maintenance time.
