What is a mainframe?

What is a mainframe?

• A. A small personal computer used for single tasks
• B. A network router used in data centers
• C. A huge computer that ran one application
• D. A cloud-based storage system

Answer: (C)

Mainframe computers are large, powerful machines built to handle massive workloads, run many applications at once, and support thousands of users simultaneously with high reliability. This description fits the idea of a huge computer that can run multiple applications and manage critical tasks for big organizations. The other options describe devices or services that don’t match that centralized, high-capacity computing role: a small personal computer is for individual use, a network router handles data routing in networks, and cloud-based storage is focused on storing data rather than performing centralized processing.
