Question

Quizplus · Accepted Answer

Legacy systems are typically older systems or software that are still in use because they perform tasks that are still needed. They are not specifically characterized by holding the middle tier of a multiple-tier system; this attribute does not accurately describe what makes a system a legacy system. Legacy systems can indeed be found on mainframes (A), are systems from the past still in use (B), may require hard-to-use command languages due to their age (D), and often contain detailed information that might be accessed by newer systems (E).
