Which statement best describes CPU vs GPU roles?

• A. CPU handles general-purpose, sequential tasks; GPU handles massively parallel compute tasks such as graphics and data-parallel workloads.
• B. CPU handles only graphics; GPU handles OS scheduling.
• C. GPU is used for sequential, single-thread tasks.
• D. CPU is specialized for graphics processing.

Answer: (B)

The main idea is the division of labor between CPU and GPU. A CPU is a general-purpose processor optimized for sequential execution and fast handling of control flow, OS tasks, and a wide variety of workloads. A GPU, with many simpler cores, is designed to run thousands of threads in parallel, making it ideal for graphics rendering and data-parallel workloads. That’s why OS scheduling and most system tasks happen on the CPU, while the GPU excels at massively parallel compute tasks. So the best description is that the CPU handles general-purpose, sequential tasks; the GPU handles massively parallel compute tasks such as graphics and data-parallel workloads.
