Which of the following is NOT listed as an aspect that can cause errors in computer systems?

• A. Bad Programming
• B. Poor Training
• C. Poor Procedures
• D. Outdated Hardware

Answer: (D)

When a question focuses on factors that can cause errors in computer systems, it often points to human and procedural issues. Bad programming directly introduces defects in software, which can cause errors when the program runs. Poor training leads to operator mistakes or wrong handling of systems, producing errors in use. Poor procedures create inconsistent steps and practices, which open the door to mistakes and faulty outcomes.

Outdated hardware, while it can cause performance slowdowns or compatibility problems, isn’t considered one of these human- and process-related error factors in this framing. It’s a hardware condition rather than a flaw in programming, training, or procedures, so it’s the item that doesn’t fit with the others.
